Septic Tanks

Septic Tanks

Owls Hall have a wide range of septic tanks suited for both residential and commercial properties. Browse our full range of products and purchase online today.

A Septic Tank is a system designed to treat wastewater where no mains sewer connection is available. The treated water is suitable to discharge through the ground via a suitably sized drainage field. A septic tank must be tested in accordance with EN12566/1 and sized correctly, you can use our free septic tank sizing calculator to help, or call us and we can advise you.

Septic tanks are made from GRP, or more modern versions from polyethylene, which like the Premier tech Septic tank often have fine particle filters to help reduce suspended solids from the water and increase the lifespan of the drainage field.

If you are discharging to a ditch you will need to use a Sewage treatment plant.
