Expert sewage treatment plant installation in Blandford Forum

Living in the beautiful Dorset countryside, especially around Blandford Forum and the surrounding villages, often means you're tucked away from the main sewer lines. While the peace is lovely, managing your own waste water can be a bit of a headache if your system isn't up to scratch. At Drainage South Ltd, we've spent years helping local homeowners and businesses navigate the complexities of off-mains drainage. Whether you're building a new home near the River Stour or your old septic tank has finally seen better days, we're here to provide a stress-free, turnkey solution that keeps you on the right side of the law.

Why Choose Us?

Is your current septic tank legal?

Many property owners in Dorset aren't aware that the rules changed significantly in 2020. Under the Environment Agency's General Binding Rules, it's now a criminal offence to discharge raw effluent from a septic tank directly into a watercourse, such as a ditch or stream. If your system is old, it likely needs an upgrade to a modern sewage treatment plant. We specialise in septic tank replacement, swapping out failing, non-compliant systems for high-efficiency plants that produce much cleaner effluent. Not only does this protect our local environment and the Dorset Area of Outstanding Natural Beauty, but it also 'future-proofs' your property for when you eventually decide to sell.

Who We Are

Cleaner waste water for a greener Dorset

A modern sewage treatment plant is a massive leap forward from a traditional septic tank. These systems use mechanical components to aerate the waste, encouraging 'friendly' bacteria to break down the organic matter (measured as BOD or Biochemical Oxygen Demand). The result? The liquid leaving the tank is significantly cleaner. Our team installs durable, high-quality GRP (Glass Reinforced Plastic) tanks from industry-leading manufacturers. These plants are designed to be discreet, odour-free, and incredibly reliable, ensuring your home functions exactly like it's on the main grid, even when you're miles from the nearest sewer pipe.

Our start-to-finish installation process

We don't just turn up and start digging; a successful sewage treatment plant installation requires careful planning. We handle the entire journey for you. It starts with a free, no-obligation site survey where we assess your property's specific needs. From there, we perform a mandatory percolation test to check how well your soil can handle treated effluent. This is vital in areas around Blandford Forum where clay soil can sometimes make drainage tricky. Once we've designed a bespoke system—including the drainage field or infiltration system—our local engineers carry out a seamless installation. We even take care of the final commissioning, making sure everything is powered up and running perfectly before we leave.
