Why Choose Us?

Is Your Old Septic Tank Breaking the Law?

Many homeowners in the New Milton area are unaware that the rules regarding off-mains drainage changed significantly in 2020. Under the General Binding Rules, it is now illegal to discharge raw effluent from a septic tank directly into a watercourse, ditch, or stream. If your system is still doing this, you could face heavy fines from the Environment Agency. A septic tank replacement with a modern wastewater treatment plant is the most effective way to stay compliant. These systems use power to treat the waste to a much higher standard, resulting in a clear, odourless liquid that is safe for the environment. Not only does this protect our beautiful local rivers and the New Forest ecosystem, but it also adds significant value and 'sellability' to your property.

Who We Are

Why Choose a Modern Treatment Plant Over a Septic Tank?

While an old septic tank simply settles waste, a modern sewage treatment plant actively treats it. This means the effluent leaving the tank has a much lower BOD (Biochemical Oxygen Demand), making it far kinder to the Dorset and Hampshire countryside. These units are typically made from durable GRP (Glass Reinforced Plastic), meaning they are built to last for decades. When you choose Drainage South Ltd, you aren't just getting a tank; you're getting a future-proof solution. Modern plants are incredibly quiet, produce minimal odour, and require much less frequent emptying than older systems. It's a 'fit and forget' solution that gives you complete peace of mind.

Our Professional Turnkey Installation Process

We believe in a 'turnkey' approach, meaning we handle every single detail so you don't have to. The journey begins with a free, no-obligation site survey in New Milton. Our drainage engineers will perform a percolation test to check how well your soil absorbs water, which is vital for designing a successful soakaway installation or infiltration field. We then design a system tailored to your property's size and usage, manage all the necessary paperwork with the Environment Agency or local building control, and carry out the physical installation with minimal disruption to your garden. Finally, we perform a full commissioning of the plant to ensure everything is running at peak efficiency before we hand it over to you.
