Expert Septic Tank Installation Across Devon
NADC accredited specialists for compliant & reliable off-mains drainage.

Installing a septic tank or a wastewater treatment plant is a significant undertaking that requires careful planning and execution. Our experienced engineers begin with a thorough site assessment, including critical soakaway percolation tests to determine the soil's suitability for drainage. We then help you choose the right type and size of tank or plant for your property's needs, considering factors like the number of occupants and daily water usage. The process typically involves excavation, precise positioning of the tank, connecting the incoming drainage pipes, installing the outflow to a drainage field (soakaway) or a watercourse, and ensuring the entire system complies with current building regulations and environmental standards. We manage the whole project, providing a high-quality, long-lasting solution.

You might need a new system if your existing septic tank is old, failing, or no longer compliant with current regulations, particularly the 2020 General Binding Rules. Signs of a failing system include foul odours, waterlogging in your garden, slow-draining toilets or sinks, or sewage backing up. For new builds or properties without mains drainage, a new installation is essential. We can help you decide between a traditional septic tank (which discharges to a drainage field) and a modern wastewater treatment plant (which produces cleaner water suitable for direct discharge to a watercourse if permitted), explaining the environmental benefits and maintenance requirements of each.

The main regulations governing septic tanks and small sewage treatment plants are the General Binding Rules, which came into force in 2020. These rules state that septic tanks cannot discharge directly to a ditch or watercourse. If your existing septic tank discharges directly to a watercourse, you must upgrade or replace it with a sewage treatment plant or connect to a drainage field. These rules aim to protect water quality and the environment. Our team of drainage engineers are experts in these regulations and will ensure any new installation we undertake in Devon is fully compliant, providing you with peace of mind for years to come.

The cost of installing a new septic tank or wastewater treatment plant varies significantly. Factors influencing the price include the size and type of the system, the complexity of the groundworks and excavation, whether a percolation test is needed, and the specific site conditions. We provide a free, no-obligation site visit and a detailed, transparent quotation before any work begins. Our goal is to offer a cost-effective, high-quality service, avoiding any hidden charges, so you know exactly what to expect for your domestic or commercial installation project across Devon.

While modern septic tanks and treatment plants are designed for efficiency, regular maintenance is key to their longevity and proper function. This typically involves annual emptying of the tank to remove accumulated solids. Wastewater treatment plants may also require periodic servicing to check mechanical components like air blowers. We can advise on recommended maintenance schedules for your specific system. Proper maintenance prevents blockages, costly repairs, and ensures the system continues to operate effectively and environmentally. We can also provide details for local emptying services.
