Managing a marina requires a careful balance of providing exceptional customer service, maintaining high-quality infrastructure, adopting eco-friendly practices, and ensuring the safety and security of the facility. As the number of people within the boating community continues to grow, marina operators must focus on delivering an excellent experience that caters to the developing needs of potential customers. This guide outlines the best practices for marina management, with a focus on customer-centric services, facility upgrades, digital integration, environmental stewardship, and safety measures that boost boater experiences. Customer-Centric Marina Services A successful marina starts with a focus on delivering exceptional customer service. For boaters, marinas are not just docking points; they are often part of their leisure experience, and a welcoming, helpful environment is essential for retaining customers and encouraging repeat visits. Marina staff should be trained to greet boaters with a friendly attitude, offering assistance with docking, answering questions, and providing local knowledge. A marina that feels accessible and inviting will foster a sense of community among customers. Key Practices for Marinas: Staff members should be knowledgeable, approachable, and trained to respond to various boating-related questions. Having clear signage and directions ensures boaters can navigate the marina easily. A dedicated customer service desk can help address specific concerns or requests, ensuring a streamlined experience from check-in to check-out. Marinas that go the extra mile to offer personalised services stand out to boaters, with the following being great services to consider: Valet Docking: Offering valet docking can help boaters, especially those who are less experienced, dock safely and without stress. Concierge Support: Concierge services can include everything from arranging refuelling to booking local tours or providing boat cleaning services. Flexible Check-In/Check-Out: Marinas should provide flexible docking schedules that allow boaters to adjust their check-in and check-out times based on their travel plans, providing added convenience. In addition, boaters are more likely to return to a marina if they feel their feedback is valued. Regularly seeking feedback through reviews or direct surveys can provide valuable insights into what services are working and where improvements can be made. We recommend making it easy for them to provide feedback through digital platforms or in-person surveys, and always act on feedback by making changes or adjustments to services and communicating improvements with customers. Another great incentive is to reward loyalty by offering discounts or special services to repeat customers who provide feedback. Facility Upgrades and Maintenance The infrastructure of a marina is critical to the overall boater experience. Well-maintained facilities contribute to safety, comfort, and convenience, which are key elements in attracting and retaining boaters. For example, regular maintenance of docks, mooring lines, and utility connections (electricity, water, and Wi-Fi) should be essential checks, as worn-out mooring lines or damaged docks can pose safety hazards, while unreliable utilities can diminish the overall experience for boaters. Modern boaters expect a high standard of comfort when docking at a marina. Investing in clean, well-maintained amenities, such as the following can help to boost appeal: Restrooms and Showers: Keep restrooms and showers clean and stocked with essentials. Regular maintenance and deep cleaning schedules should be implemented. Laundry Services: On-site laundry facilities allow boaters who are on longer journeys to refresh their clothing without leaving the marina. Lounges and Common Areas: Creating a space where boaters can relax, socialise, and access free Wi-Fi can add significant value to the marina experience. Digital Integration and Convenience In the age of digital convenience, marinas must incorporate modern technology to improve customer interactions and streamline operations. Offering digital solutions not only enhances convenience for boaters but also improves the efficiency of marina management. Modern marinas can take advantage of digital tools to offer boaters a seamless experience from booking to check-out. Online booking platforms, mobile apps, and automated payment systems create convenience for boaters while reducing administrative workloads. Online Reservations: Allow boaters to reserve berths online, giving them the ability to book ahead, choose their preferred dock, and check availability in real-time. Mobile Apps: Implementing a marina-specific app can streamline communication, provide real-time updates on services, and give customers access to marina maps and local information. Contactless Payments: Offering secure online payment options or mobile payment methods can make transactions quicker and easier for customers. Keeping boaters informed is another crucial part of delivering an excellent marina experience. Offering real-time updates on weather conditions, tide schedules, and local events through digital platforms ensures that boaters have the information they need for a safe and enjoyable stay. Read next: A Guide to Marina Maintenance and Management Environmental Focuses for Marinas Modern boaters are increasingly aware of environmental issues, and many are looking for marinas that demonstrate a commitment to sustainability. Adopting eco-friendly practices not only helps protect waterways but also appeals to environmentally conscious customers. These eco-friendly practices can range from waste management programs to water conservation initiatives. Waste Management: Establish proper waste disposal and recycling facilities to reduce littering and promote responsible waste disposal among boaters. Water Conservation: Encourage the use of biodegradable cleaning products and provide clear instructions on how to minimise water pollution from boat maintenance. Energy Efficiency: Invest in energy-efficient lighting and heating solutions and encourage the use of solar power for boats docked at the marina. Part of being an eco-friendly marina is educating customers about sustainable boating. This may include promoting responsible fuel use, providing guidance on proper waste disposal, or offering training on best environmental practices. In addition, gaining environmental certifications, such as from the Clean Marina Program, provides official recognition of a marina’s commitment to eco-friendly practices. These certifications can attract environmentally conscious boaters and help improve the marina’s reputation. Steps to Achieving Certification Implement Best Practices: Begin by adopting the best practices outlined in environmental guidelines, focusing on areas such as water quality management, waste reduction, and energy efficiency. Audit and Assessment: Undergo an external audit or self-assessment to identify areas for improvement and ensure compliance with environmental standards. Marketing Your Certification: Once certified, promote your status to potential customers by displaying the certification logo on signage, websites, and promotional materials. Safety and Security Measures Boaters expect marinas to be not only comfortable but also secure. Ensuring that strong safety and security measures are in place is vital for the peace of mind of your customers. A secure marina includes physical barriers, surveillance, and secure access points. Installing advanced security measures ensures that both boats and their owners are protected, deterring potential theft or vandalism. 24/7 Surveillance: Install high-definition security cameras throughout the marina to monitor activity and record any suspicious behaviour. Secure Access Points: Controlled access, such as keycard systems or electric gates, ensures that only authorised individuals can enter marina premises. Patrol Services: Having security personnel or night guards patrol the marina can further enhance security and give boaters additional peace of mind. In addition to security, marinas must ensure that adequate safety measures are in place to handle potential emergencies. For example, ensuring that life jackets, fire extinguishers, and first aid kits are readily available and in good condition. It is also important to develop a comprehensive emergency response plan for situations such as fires, medical emergencies, or severe weather events is crucial. Marina staff should be trained in first aid, CPR, and basic rescue operations, with prominently display safety rules and guidelines to inform boaters about emergency protocols.

Maritime civil engineering is a highly specialised field that requires extensive experience and a unique set of skills, with engineers responsible for the planning, designing, construction, and maintenance of structures in or around the water, including ports, harbours, docks, bridges, and inland waterways. In the UK, maritime civil engineering plays a crucial role in facilitating trade, transport, and tourism, as the country has a long history of maritime engineering that dates back to the Roman Empire. Today, the UK is home to some of the busiest ports and harbours in the world, including the Port of London, the Port of Southampton, and the Port of Liverpool, and the inland waterways of canals, rivers and lakes that extend to a network of more than 2,000 miles. In this blog post we take a closer look at the maritime civil engineering profession, its history, challenges, and the advancements which are shaping the industry today. What does a maritime civil engineer do? Maritime civil engineers are highly skilled professionals who undertake several years of education and workplace training, their studies include everything from fluid mechanics and geotechnical engineering through to environmental science and the legal frameworks which govern our waterways. Engineers are able to train via a variety of apprenticeships, college programs and university courses, and once qualified they work alongside professionals within shipping, logistics, tourism, construction and environmental services to design and maintain maritime infrastructure. The history of maritime civil engineering in the UK The long history of maritime civil engineering dates back to the Roman Empire, when Romans built ports and harbours as a way to facilitate trade and transport. Moving into the Middle Ages, the engineers developed a maritime infrastructure which included docks and wharves; however, it wasn’t until the Industrial Revolution that maritime civil engineering really became vital to the economy we know today. With the growth of international trade and the invention of steam powered machines, there was a sudden demand for larger and more sophisticated ports, harbours, canals, and rivers. The maritime engineers of the time responded by creating innovative new designs which used the latest construction techniques. Although we no longer rely upon the network of canals for transportation of goods, UK engineers are still some of the most qualified professionals in the world. The maritime civil engineering industry today From the canals built during the industrial revolution to the construction of the first purpose-built container port in the UK in Felixstowe in 1967, the UK has always led the way for maritime civil engineering. The industry today is thriving and here at The Rothen Group, we are proud of our engineers who work on some of the most important projects in the UK. Although times have changed since the Industrial Revolution, the UK waterways still support the movement of goods and people, whilst providing recreational opportunities and enhancing the country’s natural beauty. The importance of the maritime network in the UK is exciting, and there are a range of important projects and developments on the horizon. A great example is the government’s commitment to zero-emission transport, which will create a need for the development of electric and hydrogen-powered boats, and maritime civil engineers will be heavily involved in the design of the infrastructure needed to support these modern vessels. In addition, the waterways themselves will need to become more efficient and sustainable, with engineers tasked with creating solutions that use the flow of water to generate electricity as a renewable source of energy. What challenges does the industry face? Despite the exciting developments within the industry, there are some challenges. For example, it is important that the infrastructure within the UK waterways is modernised and upgraded to keep up with evolving demands. Many of the rivers and canals in the UK were built in the 18th and 19th centuries, and urgent ongoing maintenance is needed to ensure they remain operation. The government has invested more than £4 billion into the development of these waterways, and through our vast range of services we are proud to be a leading supplier of maritime engineering solutions.

A marina might look calm on the surface, but behind the scenes there is always something to manage. From berth allocation and customer safety to dredging, repairs, and maintaining access, marinas are complex waterfront facilities that require constant attention. One of the biggest ongoing tasks is maintenance. A marina must remain safe, accessible, and usable for both customers and boats. Below, we explore what marina management involves, why regular maintenance matters, and the equipment and expertise needed to keep a marina operating effectively. In this article we'll discuss: What is a Marina? Why Does a Marina Require Maintenance? Who Maintains and Manages Marinas? How to Carry Out Marina Maintenance What Workboats are Required for Marina Maintenance? Marina Maintenance with The Rothen Group What is a Marina? A marina is a place to moor boats and yachts. Once there, people can carry out repairs, restocking, or other maintenance tasks. Often, boats are stored in marinas for long periods. Due to size constraints, many inland marinas are limited to smaller boats. Traditionally, a marina referred to an area along a coastline. However, today, the term is also commonly used for inland facilities where canal boats or other small vessels are moored. What Purpose Does a Marina Serve? Marina design and construction involve providing security and useful facilities while ensuring moorings aren’t disturbed by passing boats. Every marina is different, with some offering only basic facilities. More complex waterfront developments, however, can include cafés, barbecues, boater storage, and more than 500 berths. Marina construction commonly involves installing jetties and facilities such as toilets, waste disposal points, showers, and car parking. Some waterfront developments also include both dry and wet dock facilities. Why Does a Marina Require Maintenance? Marina infrastructure is broadly made up of bankside protection, such as sheet piling or soft bank protection, alongside jetties and other waterside structures. Over time, these can deteriorate as boats repeatedly force water against the banks while manoeuvring into berths. Common maintenance requirements include: Bank protection: Sheet piling and softer forms of bank protection can fail over time, increasing the risk of banks eroding or collapsing into the marina. Jetties and walkways: Jetties are often constructed using sheet piles and timber walkways, which can degrade as the timber ages and rots, creating hazardous walking conditions. Silt, debris, and weeds: These can build up within the marina and may need to be removed through maintenance methods such as dredging. If left unmanaged, these issues can restrict access, create safety risks, and make it harder for boats to move around the marina. No matter its design or construction, active maintenance is therefore essential. What Happens If You Don't Maintain a Marina? Water is the enemy of most infrastructure. If left, banks and bank protection will gradually fail. Jetties and walkways can become hazardous. The gradual accumulation of silt can reduce navigable depth, increasing the risk that a boat grounds. Marinas are almost always businesses. Poor conditions can affect the experience of customers, forcing them to relocate. That can negatively impact the survival and financial viability of the marina. Moreover, by ignoring regular maintenance, problems become more expensive and difficult to repair. But with the right maintenance, it’s relatively easy to stay on top of most maintenance tasks. Who Maintains and Manages Marinas? Marinas are usually maintained by a marina manager or operator. Routine jobs are handled onsite. That could include weed removal, some minor jetty repairs, or testing silt levels. However, marinas often rely on contractors like The Rothen Group for specialist work such as dredging, piling, bank stabilisation, and jetty installation/repair. Marina managers therefore need to identify problems and coordinate specialist work. Using Marina Management Software Marina management software keeps the marina working smoothly. It helps allocate berths and plan bookings weeks or months in advance. The system then logs customers and vessels, providing a reliable record. The best software can even bill customers or send automatic reminders for maintenance. Overall, it helps manage operations, making the life of a marina manager much easier, but it doesn’t replace actual physical inspections. How to Carry Out Marina Maintenance Marina maintenance should mostly be routine. That could be removing weeds or inspecting the marina. A thorough inspection evaluates the jetty condition, bank stability, and silt levels. Based on the findings, the marina may require piling, bank stabilisation, dredging, or jetty repair and installation. Most marinas aren’t equipped to handle this kind of work themselves. It’s best to speak to an experienced contractor who specialises in marina maintenance. This involves obtaining a quote to see if further labour and expertise are required to carry out the project. Following Regulations when Maintaining Marinas Marinas are subject to numerous regulations when it comes to maintenance. Health and safety requirements will apply universally. For dredging, bank work, or other maintenance needs, marinas will need to obtain environmental permissions from the relevant authorities. This can vary depending on the site, water quality, and surrounding habitats. If you hire contractors, ensure they follow the appropriate regulations and working practices. As the site owner or manager, you will be responsible for any issues. What Workboats are Required for Marina Maintenance? The Rothen Group supplies a broad range of adaptable marina engineering equipment, allowing maintenance to be carried out from either the bank or the water. Suitable craft include: Crane boats for lifting and moving heavy materials. Digger pontoons for dredging and excavation work. Weed cutting boats for vegetation clearance. Pusher tugs for manoeuvring floating plant. Hoppers for transporting dredged material and debris. Because many marinas were originally constructed in dry conditions, marina contractors do not always own specialist floating plant. However, these vessels can be invaluable when carrying out repairs and maintenance within an operational marina.

Canals can collapse extremely quickly, sometimes in a matter of hours. Sections of canal bed or embankment disappear, leaving boats stricken. In one alarming case at a Shropshire canal in 2025, an “embankment failure” caused water to rush into a nearby field. Locals saw two narrowboats sinking into a hole during the early hours of the morning. Canal sink holes are often behind these events. Water leakage, erosion, unstable geology, and historical underground workings combine to cause rapid water loss. The effects aren’t just immediate. They can ripple through the canal networks, triggering delays that can last weeks or even months. Not every failure is technically a sinkhole. Canal embankments can also fail, as in the case in Shropshire. Either way, understanding how canals collapse can help specialists investigate, stabilise, and repair damaged sections. In this article we'll discuss: The Difference Between a Canal Sinkhole and an Embankment Breach Top Causes of Canal Sinkholes and Bed Collapses How Engineers Detect and Prevent Canal Cavities How Waterways Specialists Fix a Collapsed Canal Section How The Rothen Group Can Help Frequently Asked Questions The Difference Between a Canal Sinkhole and an Embankment Breach Canals are prone to several different kinds of damage. The most catastrophic examples include: Canal sinkhole: A collapse in the canal bed or surrounding ground caused by an underground cavity or weakened material, often allowing water to drain rapidly into the ground. Embankment breach: A failure of the canal bank or embankment that allows water to escape sideways, potentially causing flooding, erosion, and further structural damage. They aren’t wholly unrelated. For example, a leak can create underground voids as the water moves beneath the surface. Eventually, it can produce a collapse or embankment failure. That’s why it’s critical to inspect, repair, and maintain canals. Top Causes of Canal Sinkholes and Bed Collapses 1. Dissolution of Underlying Bedrock (Karst Processes) We think of the ground beneath our feet as solid. It is, at least until water gradually dissolves soluble rocks like limestone, gypsum, or salt-bearing geology. If the dissolution and erosion are extensive enough, entire cavities can form below the surface. Eventually, the material above the cavity can no longer be adequately supported. The cavity collapses, leaving behind the characteristic sinkhole. Geological surveys and ground investigations can identify vulnerable areas. 2. Puddle Clay Lining Degradation and Leaks Most British canals were first built in the 19th century or earlier. Even with repairs, they still rely on traditional waterproofing using compacted puddle clay. This lining can deteriorate over time, becoming cracked, disturbed, or damaged. Water can then seep through the clay, washing fine soil particles out of the ground beneath the canal and creating cavities. 3. Historical Mining Shafts and Underground Voids Canals often pass through areas with historical mine shafts, tunnels, culverts, or other buried structures. In fact, that’s why the canal might have been built: to ferry coal or minerals from one site to another. The problem in the modern day is that these structures can remain below or close to waterways. Given that historical records are not always complete or accurate, water can gradually erode the ground before reaching the void. The resultant collapse can be very dramatic. 4. Burrowing Animals and Structural Soil Erosion Perhaps the strangest reason for canal sinkholes is animal burrowing. Burrows don’t have to be big; they simply have to penetrate into the canal. They then offer a pathway for water to exit structures that would otherwise remain relatively watertight. The flow of water enlarges the channels in a process known as piping, where progressively more material is carried out of the embankment. Alongside burrowing animals, vegetation, roots, and damaged banks may create additional weaknesses. The Rothen Group offers habitat restoration services, planning carefully around existing waterways to avoid these outcomes. 5. High Water Pressure and Extreme Weather Heavy rainfall can temporarily saturate canal embankments and surrounding ground. The flooding increases hydraulic pressure and erosion, potentially overwhelming already weakened ground. Drought has the reverse effect. It can dry and crack clay-based structures. When water returns, the cracks offer a way for the water to escape. Embankment maintenance How Engineers Detect and Prevent Canal Cavities Prevention begins with inspection. Instead of waiting for visible collapse, canals should be properly surveyed for warning signs. Engineers look for: unexpected drops in water level; wet ground or seepage around embankments; cracking or subsidence; unusual vegetation changes; erosion; deformation of banks or towpaths. Even if the evidence isn’t obvious, boreholes, trial pits, ground-penetrating radar, and geophysical surveys can help see what’s hidden below the surface. To prevent canal collapse, preventative work is carried out, including lining repairs, grouting cavities, drainage improvements, embankment strengthening, vegetation management, and erosion control. How Waterways Specialists Fix a Collapsed Canal Section A sudden canal breach poses an immense problem. First, the aim is to make the area safe, restricting navigation and access. The affected section of canal is isolated with planks and temporary dams, using pumps to control the water where necessary. Next, the site is investigated to identify the cavity and underlying cause. Any unstable material is removed, and underground voids can be filled. The canal bed and embankment are reconstructed, reinstating waterproof lining. Once the canal itself is functioning, adjacent infrastructure like towpaths, banks, and drainage systems can be repaired. How The Rothen Group Can Help Canal sinkholes and breaches can develop for many reasons, from leaking canal linings and underground voids to erosion, unstable ground, and extreme weather. While the final collapse may appear sudden, the underlying damage has often been developing for much longer. Preventing sudden collapse requires regular inspection and maintenance. They can identify weaknesses before they develop into major structural failures. Contact The Rothen Group to discuss canal damage, bank erosion, collapsed sections, or wider waterway maintenance requirements. Their specialist team provides canal repair and maintenance services across the UK, including work on failed linings, eroded banks, and structurally damaged sections. Frequently Asked Questions Why do old historic canals collapse so suddenly? Historical canals simply have more time for the damage to occur. It can progress unnoticed for long periods, gradually leaking water into the soil and creating significant cavities. Where in the UK have canals had a sinkhole or breach? Examples include the Llangollen Canal at Whitchurch, the Middlewich Branch of the Shropshire Union Canal, the Ashby Canal, and the Macclesfield Canal. These incidents have involved both embankment breaches and collapses associated with underground voids or damaged structures. How long does it take to repair a canal? There is no standard timeframe. It depends on the size of the leak. Major collapses can take weeks or months to repair, especially if there are deep cavities and unstable geology.

Walk near your local river or canal, and you might see signs warning about blue-green algae in the water. As the weather gets warmer, canals, rivers, and reservoirs can become breeding grounds for this microscopic creature. This can be dangerous for both people and animals. Unfortunately, most people don’t know what blue-green algae looks like, why it’s harmful, or what they can do to safeguard themselves and their pets. Below, we explain everything you need to know about blue-green algae, so you’re ready during the next bloom period. In this article we'll explore: What is Blue-Green Algae What Causes Blue-Green Algae How to Identify a Harmful Algal Bloom (HAB) Why Cyanotoxins are Dangerous Current Treatment and Prevention Methods What to Do if You Spot a Bloom The Impact of Climate Change on Algae Protecting Waterways from Blue-Green Algae Frequently Asked Questions What is Blue-Green Algae? Blue-green algae, or BGA, is not actually algae. It’s a cyanobacteria (literally blue bacteria) that looks and acts a lot like algae, hence the confusion. Under the right conditions, the BGA will “bloom,” rapidly proliferating. You can easily spot it as green mats on the surface of the water. What Causes Blue-Green Algae? Blue-green algae are naturally found in most water bodies. In small numbers, they’re not harmful. However, when the water is shallow, warm, and undisturbed, it can become a breeding ground for the microscopic creatures, especially if there’s a steady supply of nutrients. That’s what makes canals, rivers, and reservoirs such a problem. They often have all three conditions during the summer months. When Does it Appear? Under favourable conditions, blue-green algae can multiply rapidly, allowing blooms to develop over days or weeks. Usually, numbers start to increase in the spring and summer due to the run-off fertiliser from surrounding fields or upstream. That fertiliser acts as a sudden rush of nutrients, creating the conditions for runaway growth. You may notice a particular river or section of canal gradually accumulates this green matting or becomes discoloured at the same time every year, reaching its peak in July-August. Then, during the autumn and winter weather, the lack of light causes the algae to die and decompose. How to Identify a Harmful Algal Bloom (HAB) The "Spilled Paint" and "Pea Soup" Visual Cues The most obvious sign is the colour of the water. The water becomes less clear, often with a green, blue-green, or greenish-brown tint. If the algae bloom is especially bad, it may form green mats on the surface of the water. Dead Fish and Foaming Shorelines When the cyanobacteria form mats, they block out light from entering the water. It also consumes a lot of oxygen. That can kill off any fish living in the section of water. You may also notice foaming on the shore. Why Cyanotoxins are Dangerous The main danger of blue-green algae comes from the toxins some cyanobacteria produce. Known as cyanotoxins, these chemicals can affect the liver, nervous system, and skin. Not every bloom is toxic, but it is impossible to tell just by looking at the water, which is why all blooms should be treated with caution. Symptoms in Humans Most people only experience mild symptoms after contact with contaminated water. These can include: Skin irritation or rashes Red, sore eyes Nausea, vomiting, or diarrhoea Headaches Flu-like symptoms Anyone who feels unwell after exposure should seek medical advice. Why Dogs are Most at Risk Dogs are particularly vulnerable because they often swim in affected water, drink from rivers and canals, or lick contaminated fur after leaving the water. Symptoms can appear quickly and may include: Excessive drooling Vomiting and diarrhoea Weakness or collapse Tremors or seizures Blue-green algae poisoning can be fatal in dogs, so immediate veterinary attention is essential if exposure is suspected. Current Treatment and Prevention Methods There is no single solution for blue-algae blooms. Often, local authorities or private owners will put up a sign warning visitors and will allow the algae to naturally die off during the cooler months. Biochar Filtration and Nutrient Stripping Biochar is a charcoal-like material produced from organic matter. If placed into ponds, reservoirs, and treatment systems, it absorbs nutrients (particularly phosphorus), depriving cyanobacteria of a vital ingredient for growth. It’s best used as a preventative measure rather than a cure once a major bloom has developed. You’ll often find it used in sustainable water treatment programmes. Ultrasound and Algaecide Solutions Ultrasound waves can disrupt cyanobacteria cells. It helps prevent the algae from floating to the surface and forming dense mats. While it won’t get rid of the algae entirely, it can stop the algae from killing off other species. Algaecides are chemicals designed to kill algae. It’s generally considered a last option for severe blooms, as the algae can release toxins into the water when they die. What to Do if You Spot a Bloom If you think you’ve identified an algae bloom, the most important thing is to keep yourself and your pets away from the water. You might also want to contact your local authority about the bloom to help warn other people. The Impact of Climate Change on Algae Climate change can lead to rising summer temperatures and heavier rainfall incidents. More rain means more land run-off, providing extra nutrients for the algae. Together, these effects of climate change can make algae blooms more severe, especially during the summer and autumn months. Protecting Waterways from Blue-Green Algae Blue-green algae can pose a serious risk to people, pets, and wildlife. Fortunately, by recognising the signs of a bloom and acting quickly, you can reduce the risk of exposure and limit its impact. Need support managing water quality?

Frequently Asked Questions Can I tell if blue-green algae are toxic just by looking at them? No. There’s no way to tell toxic from non-toxic BGA at a glance. That's why it's important to be cautious around any water with high levels of BGA. What are the symptoms of blue-green algae poisoning in dogs? If your dog is exposed to BGA, you may notice excessive drooling, vomiting and diarrhoea, weakness or collapse, or tremors or seizures. Blue-green algae can be fatal in dogs, so immediate veterinary care is advised. How do I treat a pond with blue-green algae? Depending on whether there are any fish in the pond, you can consider either biochar, ultrasound, or algaecide. Algaecide is the quickest solution, but it can harm fish species. Alternatively, identify the source of excess nutrients to prevent future blooms.

Droughts are becoming a normal part of British summers. As of August 2026, almost three-quarters of England is in an official drought due to a combination of very low rainfall and higher temperatures. Much of the news focuses on hosepipe bans, wildfire concerns, and the impacts on agriculture. However, in early August, the Environment Agency reported 26 canal navigation closures and 19 restrictions caused by water shortages. The previous year points to a recurring problem. At the peak of the 2025 drought, around 20% of the canal network temporarily closed, and seven in ten surveyed boaters said they could not navigate as planned. In this article we'll explore: How Drought Impacts the UK’s Canal Network How Drought Affects Boating and Canal Holidays Ecological and Environmental Consequences Structural Risks to 200-Year-Old Infrastructure The Economic Ripple Effect on Tourism and Local Businesses How Canals Can Support National Water Resources Protecting the Canal Network Through Hotter, Drier Summers Frequently Asked Questions How Drought Impacts the UK’s Canal Network Canals continuously lose water, even when few boats are moving. Rainfall is needed throughout the year to replenish the reservoirs, streams, and other sources feeding the network. When rainfall stops or slows, the canal network starts to drain. Dropping Water Levels and Reservoir Supplies Prolonged periods of low rainfall reduce the amount of water entering canal-feeding reservoirs. Unlike rivers, water isn’t constantly moving in a canal. But it does move downhill via locks; heavily locked routes require especially large and reliable supplies. Usually, canal managers can replace lost water by releasing it from reservoirs, but when reservoir levels fall critically low, they have few options. In summer 2026, England’s reservoir storage fell by 16% during July, the largest July reduction in raw water storage for at least 30 years. How Evaporation on Hot Summer Days Contributes It’s not just water lost to locks. Continually hot days cause direct evaporation from the water surface alongside transpiration from bankside plants. The Canal & River Trust estimates that canals can lose as much as one inch of water through these processes on a hot summer day. Considering that by mid-July 2026, the UK had already experienced more days above 30°C than during the whole of 1976, it’s not hard to see how it can exacerbate an already fierce drought. How Drought Affects Boating and Canal Holidays Reduced Lock Hours and Water-Saving Measures Lock usage is one of the most common sources of water loss in canals. Authorities may, therefore, limit lock operation to certain hours, group boats together, or introduce supervised passages to minimise overall water loss throughout the system. Other measures can include pumping water back uphill, lowering canal pounds to their minimum navigable level, and suspending non-essential movements. Canal Closures and Shallow-Water Hazards If water levels get critically low, authorities may close locks, flights, or entire canal sections. Shallow water increases the likelihood of boats grounding, striking submerged objects, or becoming trapped in pounds between locks. Ecological and Environmental Consequences Threats to Aquatic Life Canals are home to fish, insects, and aquatic plants. Warmer water holds less dissolved oxygen, while shallow water heats more quickly. Together, these factors can stress fish and other species. In the worst cases, nutrient-rich, slow-moving water creates favourable conditions for algal blooms, which block sunlight and cause oxygen levels to fall further when algae die and decompose. In severe cases, this can kill fish and other aquatic life across a section of the canal. Canals as Refuges for Wildlife Canals thread their way through cities, farmland, and fragmented habitats, often functioning as wildlife corridors. During a drought, they can be one of the last remaining aquatic habitats when ponds, ditches, and smaller streams have dried out. That means canal managers must balance human needs with wildlife concerns. Even so, the concentration of wildlife in shrinking areas of water can increase competition, disease risk, and vulnerability to low oxygen. Structural Risks to 200-Year-Old Infrastructure Many British canals were built more than two centuries ago using clay-lined beds, earth banks, masonry locks, and other materials that were never intended for a warming world. All of these structures come under immense stress and respond badly to repeated drying and rewetting. Drying Canal Beds, Bank Cracking, and Seepage Leaks Clay-lined canals aren’t watertight even at the best of times. Excessive drying can shrink and crack the clay. When water returns, it may escape through newly formed gaps. Falling levels may also reveal erosion, voids, damaged bank protection, or leakage around locks and other structures. For The Rothen Group, it means professionally inspecting canals, performing targeted repairs, installing piles, and strengthening the existing canal banks. The Economic Ripple Effect on Tourism and Local Businesses Like any thoroughfare, canals support numerous businesses: pubs, cafes, marinas, boat-hire companies, and waterside accommodation, to name a few. Route closures can lead to cancellations, refunds, reduced bookings, and additional costs for repositioning boats. Entire hubs can struggle, and some businesses will not survive. How Canals Can Support National Water Resources Canals are not simply recreational waterways. They serve a vital purpose, supplying water to third parties and acting as established routes for moving raw water between regions. There are even options to expand this role. The Grand Union Canal Transfer would use sections of the canal network to help move raw water towards areas facing future supply shortages. It could be a major drought mitigation strategy. Protecting the Canal Network Through Hotter, Drier Summers Droughts place immense stress on the canal network. Reduced supply and greater evaporation can lead to disrupted navigation, ecological stress, and even closures of stretches of a canal. With England experiencing drought in both 2025 and 2026, investing in regular maintenance and long-term climate resilience has never been more important. The Rothen Group provides specialist canal maintenance, bank protection, piling, grouting, dredging, and habitat restoration services. Whether you need to repair an existing problem or make a waterway more resilient to future extremes, contact our team to discuss the right solution. Frequently Asked Questions Why do canals lose so much water during dry weather? Most water is lost through seepage from ageing canal beds and banks. Evaporation, transpiration, lock use, and leaking gates also contribute. How do authorities manage canal water during a drought? Authorities monitor reservoir levels, restrict lock hours, group boats together, pump water between sections, and repair major leaks. Severely affected stretches may be temporarily closed. Does drought harm wildlife in UK waterways? Yes. Shallow water warms quickly and holds less oxygen, placing fish and other aquatic life under stress. Drought can also encourage harmful algal blooms. How do canals avoid running out of water? Canals are replenished from reservoirs, rivers, streams, groundwater, and pumped transfers. Water levels are carefully managed, although severe drought can still cause shortages. Do canals ever dry up? Yes. Individual sections can become extremely shallow or partially dry during severe drought. Authorities try to retain enough water to protect wildlife and prevent damage to canal beds and locks. Where does the water come from to fill canals? Canal water comes from rainfall-fed reservoirs, rivers, streams, springs, boreholes, and surface runoff. Pumps and transfer systems are also used to move water around the network.

Here at The Rothen Group, we have significant experience in the design and installation of all forms of marine piling, whether the project is situated in a land-based environment, tidal or intertidal location. Types of marine piling works Marine piling, often referred to as aqua piling, involves the use of posts which are driven into the ground underwater to provide support to building works, such as building retaining walls and marine structures. There are many types of marine piling options, with a common form being sheet piling. These are steel sheets which interlock along a river or canal bank to protect it from collapsing, so they are commonly used along towpaths and to create a waterside feature. The sheet piles can often stabilise banks for more than 20 years and are a key method used by our team to prevent floods and to ensure the waterways across the UK remain clear, safe, and navigable. Here at The Rothen Group, we are pleased to offer a comprehensive range of marine piling services including the following examples: Quay walls Dock wall stabilisation Jetties Slipways Mooring dolphins Tubular piles Pontoons River walls Whatever the scale of your project, our skilled team take pride in delivering projects efficiently, safely, on time and within budget. Steps involved in marine piling projects The process always begins with a feasibility assessment, where our experienced team of engineers will consider all aspects of the project including ecological factors, the water depth, health & safety, access, ground conditions and your budget. We will then present our proposal which will include details of the materials we recommend using, which in many situations is marine grade steel. As piles are submerged in water it is important to choose materials which guarantee longevity and excellent load-bearing capabilities, and steel offers excellent corrosion resistance especially when it is galvanised for extra protection in the water. Depending on the site, we may also recommend a concrete pile system which is known for its strength, alternatively wood piles are an attractive option for areas with low oxygen water levels. We will also outline the machinery we plan on using, which will usually involve our specialist floating crane barges and digger boats. Every marine piling project is unique, but we have the experience, equipment, and capabilities to complete projects across the UK waterways, rivers, and canals. Whether the project is situated on a river, lake, marina or waterway, our operatives have extensive knowledge of piling within marine environment and we can effectively overcome all challenges with our extensive fleet.

There are many types of sheet pile driving equipment, and there are many sheet pile driving methods. In fact, we have previously looked into what types of pile driving equipment would be best for your project. Here, we will explore the pile driving equipment itself. So, to find out more about air, vibratory and hydraulic piling hammers, and the range of piles and elements they are used with, read on. Air Pile Hammers The term ‘air pile hammer’ can refer to many types of pile driving equipment, with a common similarity – they all use compressed air to drive piles into the ground. These sheet pile hammers are well-suited to driving light pile sections, and for trench sheeting. Alongside plastic piling and timber piles and posts, they can also be used to drive multiple other items depending on their configuration and design. The performance of air pile driving hammers has made them a popular choice of equipment. The Rothen Group (TRG) offers a variety of pile driving equipment for different surfaces and applications, such as the ones listed below. ARG The ARG pile driving hammer is favoured by waterway contractors, and for restoring canals and rivers, due to their ease-of-use, robustness and versatility. They can be used for H-section columns, barrier posts, jetty and mooring scaffolding, fencing posts and steel tubes. BSP 200 A lightweight sheet pile hammer that provides an 80kg weight saving, the BSP 200 boasts driving power equalling that of an ARG No. 2. BSP 300 The BSP 300 sheet pile driving machine is best-suited to sites with hard ground, and more specifically, to driving in L8 and M7 piles in these soil conditions. BSP No. 5 BSP No. 5 hammers allow for efficient pile installation by delivering a high-speed series of impact blows. Due to its periodic clamp gripping the sheet after each strike, this type of sheet pile hammer can be used effectively without damaging sheeting materials around it. It is effective as a pile driving hammer for medium-weight sheet steel, tubular, timber piles and H-Beams. The sheet pile driver can also be used with light concrete piles in soft soil and driving Larrsen piles, further highlighting its versatility. Atlas Copco 400 The largest pile hammer to use a 125cfm compressor, this piece of sheet pile driving equipment is also among the quietest in TRG’s range. This is due to the Atlas Copco’s impact being largely centred internally, and its wider leg guide option means it can be used for H-Sections, as well as posts and tubes. McKiernan-Terry Hammer This type of sheet pile driver is suitable for driving light-to-medium sheet piles. When it comes to driving power, the McKieran-Terry Hammer sits between the Atlas Copco and BSP No. 5. Hydraulic Pile Hammers Hydraulic pile hammers differ from air pile hammers in that they do not need a compressor to run. Instead, this equipment is powered by a hydraulic system, either within the machine or via a standalone hydraulic power pack. Hydraulic sheet pile drivers stand out among pile driving equipment as they offer less vibration and are highly versatile. They are compatible with multiple inserts depending on what items need to be driven in, including piles, posts and rolled steel joists. Hydraulic impact hammers also require no gas and use a biodegradable hydraulic oil, while remaining highly efficient, easy to maintain and use, as well as enjoying a low operating cost. The Rothen Group Equipment Available TRG offers two types of hydraulic piling hammer, the TR1 and TR2. Both are free-hanging pile hammers that come in three sizes to fit cranes and excavators from 2.5 tonnes upwards. The TR1 is best-suited to driving L8 sheets up to a length of 2.4 metres, with the TR2 used for the same application, but on harder ground. Each sheet pile driving machine’s hammer stroke and frequency can be adjusted, making them both flexible to specific application requirements and highly efficient. Vibratory Pile Hammer A vibratory pile hammer, otherwise known as a vibro hammer, uses vibration to loosen soil, making it easier to drive items into the surface, or remove them. These vibratory pile drivers can be simply and quickly attached to an excavator or hung off a crane, and are designed so vibration is kept to extremely low levels. They also consist of no electrics and are robust, reliable and compact. With a slim design to drive single sheet piles and minimal height, the pile length is maximised. Additionally, vibro hammers for sheet pile driving have an excellent power-to-weight ratio and are flexible over multiple applications. Thanks to the automatic operation of the hydraulic clamp, they can be used without damaging sheeting materials. Furthermore, its flow regulator prevents excessive oil supply to the vibrator. TRG stock multiple vibratory pile hammers for use in varying circumstances. These Dawson Construction Excavator Mounted Vibrators (EMVs) are used for pile driving and extraction, replacing an excavator bucket. Because they work around a standard excavator, vibro hammers of this kind are considered highly productive and cost-effective, and the different kinds are listed below. EMV70 A vibratory pile hammer suited to driving tubes, wooden posts, steel and plastic piles. The EM70 is compatible with 5-12-tonne excavators. EMV220 A mid-range vibratory pile driver, the EMV220 is 5kg heavier than the EMV70 and is often recommended in applications limited by the size of the excavator, and for piles that are heavier than trench sheets. EMV300 The largest vibratory hammer in TRG’s offering, the EMV300 is powered by 13-25-tonne excavators, and are ideal for use with mid-heavy-duty piles, such as those from Larsen.

Why Marina Design Matters As the popularity of recreational boating and waterfront developments continues to grow, the demand for well-designed marinas has never been higher. Whether catering to leisure boaters, luxury yacht owners, or commercial vessels, marinas play a vital role in supporting water-based activities. However, creating a functional and appealing marina requires careful planning, innovative design, and a deep understanding of both engineering and environmental considerations. A marina is much more than a place to dock boats. It’s a hub of activity that blends engineering, aesthetics, and functionality to serve the needs of boaters while preserving the surrounding environment. With increasing interest in water recreation and the expansion of waterfront developments, marinas must meet modern standards for safety, sustainability, and user experience. From strategic site analysis to infrastructure planning, a well-designed marina balances practicality with innovation, creating spaces that are safe, welcoming, and environmentally responsible. This comprehensive guide walks through the key steps involved in marina design and development, offering insights into the essential components of effective marina construction and operation. Step-by-step guide to designing an effective marina Step 1: Site Analysis The foundation of any successful marina design begins with a thorough site analysis. Understanding the geographic, hydrological, and environmental characteristics of the proposed location ensures that the marina will be both functional and sustainable. Key Considerations: Geographic Factors: The marina’s location must account for proximity to boating traffic, accessibility by land, and local climate conditions. Hydrological Factors: Assessing water depth, tidal ranges, and current patterns is crucial for determining vessel accommodation and safety. Environmental Factors: Evaluating the impact on surrounding ecosystems helps minimise disruption to marine habitats and ensures regulatory compliance. A site with shallow water depth may require dredging, while a location with strong tidal currents might need specialised mooring systems to secure boats safely. Analysing wind patterns also informs the orientation of docks and breakwaters to provide shelter from prevailing winds. Step 2: Marina Layout and Dock Design The layout and design of a marina are critical for maximising functionality and user experience. Effective marina layouts optimise space, provide easy navigation, and ensure safety for vessels and users. Types of Marina Layouts: Linear: Straight-line arrangements suitable for narrow water channels. Circular or Basin: Compact designs that maximise dock space in enclosed areas. Floating: Flexible configurations ideal for areas with fluctuating water levels. Dock Types and Materials: Fixed Docks: Anchored to the seabed, these are sturdy and suitable for areas with minimal tidal variation. Floating Docks: Adapt to changing water levels, making them ideal for tidal regions. Material Selection: Durable materials like reinforced concrete, aluminium, or treated wood ensure resilience against weather, saltwater corrosion, and heavy usage. Vessel Accommodation: Marinas must account for various vessel sizes, from small recreational boats to large yachts. This requires adequate berth spacing, robust mooring systems, and navigational ease within the marina. Step 3: Infrastructure and Amenities A well-equipped marina offers essential infrastructure and amenities that cater to boaters’ needs and enhance their overall experience. Essential Infrastructure: Utilities: Reliable access to electricity, freshwater, and sewage disposal is critical. Fuel Docks: Strategically located fuel stations with spill containment systems. Storage Facilities: Secure storage for boat maintenance equipment and supplies. Boater Amenities: As detailed in our article ‘Best Practices to Boost Boater Experiences’, an excellent marina should offer a balanced focus on customer satisfaction, facility maintenance, digital integration, environmental responsibility, and safety, with amenities including: Parking and Accessibility: Ample parking and easy access for visitors. Restrooms and Showers: Clean and modern facilities for boater comfort. Retail and Dining Spaces: Shops and restaurants that create a vibrant, community-friendly atmosphere. For example, marinas along the south coast of the UK are increasingly incorporating eco-friendly amenities such as solar-powered lighting and water-efficient restrooms to enhance user experience while promoting sustainability. Step 4: Environmental and Regulatory Compliance Sustainable marina development requires adherence to strict environmental regulations and proactive strategies to minimise ecological impact. Environmental Impact Assessments: Conducting comprehensive studies ensures that construction and operation activities do not harm marine ecosystems. Water Quality Preservation: Implementing filtration systems and minimising sediment disruption during construction. Habitat Protection: Designing around sensitive areas such as coral reefs or fish spawning grounds. Sustainability in Design: Using permeable paving materials for pathways to reduce runoff. Incorporating renewable energy sources, such as solar panels and wind turbines, into marina infrastructure. Promoting eco-friendly boating practices, including waste recycling and greywater disposal systems. Many UK marinas, including those operated by The Rothen Group, prioritise sustainability by creating buffer zones of native vegetation to filter runoff and protect adjacent water bodies. Step 5: Safety and Security Measures Safety and security are non-negotiable elements of marina design. A well-designed marina provides a safe environment for users and their vessels, mitigating risks through strategic features and policies. Safety Features: Lighting: Proper illumination of docks, pathways, and parking areas ensures visibility and reduces accidents. Emergency Stations: Lifebuoys, fire extinguishers, and first aid kits should be strategically placed and easily accessible. Navigational Signage: Clear signage aids boaters in safely navigating the marina and adhering to speed limits. Security Considerations: Surveillance Systems: CCTV cameras provide 24/7 monitoring to deter theft and vandalism. Access Control: Secure gates and keycard entry systems restrict unauthorised access. On-Site Personnel: Staff trained in emergency response and marina operations ensure that issues are resolved quickly and effectively. Step 6: Financial Planning Effective financial planning is essential to balance the costs of marina construction with long-term revenue-generating potential. Budgeting Factors: Construction Costs: Dredging, dock installation, and utility setup represent significant initial expenses. Maintenance Costs: Regular inspections, repairs, and upgrades must be accounted for in the operating budget. Operational Costs: Staffing, utility bills, and marketing expenses ensure the marina remains functional and appealing. Revenue Opportunities: Leasing berths to boat owners. Offering premium services, such as concierge support or storage facilities. Hosting events or partnering with local businesses to generate additional income. Step 7: Final Steps – Construction, Testing, and Launch The final phase of marina development involves executing the construction plan, testing operational readiness, and preparing for the grand opening. Construction Phase: Collaborate with experienced contractors and project managers to ensure the marina is built to specification. Maintain regular communication with stakeholders to address challenges promptly and keep the project on schedule. Testing and Trial Runs: Before opening to the public, conduct comprehensive testing of all systems, including utilities, mooring infrastructure, and safety features. Trial runs with a limited number of boats can help identify and resolve potential issues. Preparing for Launch: Marketing the Marina: Use targeted campaigns to attract boaters and local visitors. Highlight unique features such as eco-friendly designs or premium amenities. Community Engagement: Host open days or events to introduce the marina to the local community and boating enthusiasts. Leasing and Partnerships: Finalise berth leasing agreements and explore partnerships with local businesses, such as restaurants and marine supply shops, to enhance the marina’s appeal. Designing and developing a marina is a complex yet rewarding process that blends engineering, environmental stewardship, and user-focused amenities. By following a step-by-step approach—from site analysis and layout planning to sustainability and financial considerations—developers can create marinas that meet the needs of modern boaters while preserving the natural beauty of their surroundings. Whether it’s a luxury marina in a bustling urban area or a community-focused marina in a quiet coastal town, effective marina design ensures these spaces remain functional, inviting, and environmentally responsible for years to come. The Rothen Group, with our expertise in marina design and construction, is at the forefront of creating innovative solutions tailored to the unique challenges and opportunities of the UK’s waterways.

Dredging a lake, dredging a river, or canal dredging requires a set of specialist equipment like drag heads and suction pipes. These are used to remove organic sediment from lakes and ponds or other bodies of water that require dredging work. Litter and other debris is removed in the same process. Dredging projects improve water quality and prevent buildups of toxic gases that can occur on the bottom of ponds, canals and rivers. Dredging is not only important for maintaining waterways, lakes and ponds, but it also has eco-friendly benefits. As silt and sediment wash downstream, they can build up to levels unsafe for fish and other animals. Plants can find it difficult to thrive in water that has too high levels of sediment. The problem is made even worse if dredging has been neglected for several years, or if the sediment is contaminated or filled with pollutants. Without regular maintenance, including dredging, ecosystems can struggle. The quality of water is reduced and bacteria can spread making the area unsafe and unpleasant. Dredging is a necessary task to be carried out regularly to ensure that all who use the water can enjoy doing so with fewer risks. When deposits build up, it can become a flood hazard as well. Enough of a buildup can grow into an obstruction that will cause water to spill over its banks. During periods of heavy rainfall, this can lead to flooding which can be extremely dangerous and cause extensive property damage that is costly to repair. The action of dredging is similar to scooping. Unlike a trailing suction hopper dredger (TSHD) which works like a vacuum cleaner, most mechanical dredging involves physically scooping material deposits. Water is allowed to run off so excess fluid is not needlessly transported to the discharge site. A hopper is a container for loose material. In the case of hopper dredgers, the hopper contains the silt, litter, and plant matter removed when dredging a pond. Once the dredging is complete, the hopper is transported to an appropriate location for emptying. There might be special safety or environmental considerations to take into account when emptying a hopper. This depends on what has been dredged up during the project. Hoppers are emptied at discharge sites. Assuming the silt is uncontaminated, it can be dried and transported via lorries to farms. It can then be reused as a healthy natural fertiliser. The Canal & River Trust and other environment agencies work with contractors like The Rothen Group (TRG) to carry out dredging activities. This may include hydraulic dredging, mechanical dredging, or even land reclamation. A hopper dredger is most often used in maintenance dredging. Dredging a canal is not as simple as dragging up deposited material and placing it in a hopper to be removed. Canals are lined with a special clay called puddling clay. This is a vital part of a canal’s ability to function as it prevents leaks into the surrounding earth. If a dredger, digger, or long reach excavator were to break the puddling clay, it could cause a very expensive leak. Because of this, it is important that dredgers are operated by highly trained experts. Depending on the site, dredging equipment may be able to be placed on the river or lake bank. At other times, where access to the site is more difficult, TRG uses its fleet of workboats to transport machinery. Cities that have canals running through often need to be accessed via the water, as walkways and towpaths are not suited to transporting heavy machinery. Once in the right place, hydraulic powerpacks extend four stability legs into the riverbed or lakebed, keeping the equipment level and safe to work with. From waterways maintenance to towpath construction, it is vital to consult with experts on every type of marine engineering, including hopper dredging. TRG, for example, can provide expert guidance on equipment rental and give specialist advice on bespoke marine projects.
