Septic Tanks

Our range of modern and efficient septic tanks

Traditionally, most homeowners used a septic tank to treat domestic wastewater as that was the most popular and economical solution available especially where mains drainage was not available. They are designed to provide only basic treatment of wastewater which is not ideal. While they are a cost effective solution, they are poor performing and ultimately cause huge mental and financial stress to the homeowners apart from pollution to the watercourses.
The Environment Agency has therefore banned the discharge of wastewater treated by septic tanks directly to a watercourse such a river or a stream. Any septic tank that discharges directly to a watercourse such as a river or a stream will need to be replaced or upgraded to a sewage treatment plant or a package treatment plant. Wastewater discharged from a sewage treatment plant is absolutely safe and clean enough to be discharged into a watercourse. Our range of septic tanks have now been replaced with more modern Sewage Treatment Plants.
