Why Choose Us?

Is Your Current System Meeting The 2020 General Binding Rules?

Many homeowners we chat with aren't aware that the rules changed significantly in 2020. Under the Environment Agency's General Binding Rules, it's now illegal for a standard septic tank to discharge directly into a watercourse, such as a ditch, stream, or river. If your property is near the River Stour or the Avon, this is particularly important. Failing to upgrade can lead to heavy fines and will almost certainly stall the sale of your home. We're here to help you future-proof your property by replacing outdated tanks with modern, high-efficiency sewage treatment plants that meet every legal requirement.

Who We Are

Benefits of Switching to a Modern Treatment Plant

Why choose a treatment plant over a traditional septic tank? The main difference is the quality of the effluent. Modern plants use mechanical components to treat the waste, resulting in much cleaner water that can often be discharged safely into a drainage field or, with the right permits, a watercourse. These systems are incredibly durable, often made from high-quality GRP (Glass Reinforced Plastic), and they're designed to be discreet and odour-free. It's a cleaner, more environmentally conscious way to manage your home's waste, especially in sensitive areas like the New Forest border or the Purbecks.

From Percolation Tests to Final Commissioning

We don't believe in a 'one size fits all' approach. Every property in Bournemouth and Poole has different soil conditions—from the sandy stretches near the coast to the heavier clay further inland. Our process starts with a detailed site survey and a percolation test. This is essential for determining how well your ground can soak up treated water. Once we've got the data, we'll design a system tailored to your household's size and the local geography. We handle everything: the excavation, the pipework, the electrical connection, and the final commissioning to ensure your plant is running perfectly from day one.
