We install safe and efficient sewage treatment solutions

A Sewage Treatment Plant (STP) operates similarly to a septic tank but includes additional biological treatment stages to break down waste. This results in a significantly cleaner and more environmentally friendly discharge.

Wastewater and sewage are collected in a primary chamber where solids settle and lighter substances, such as grease and oil, float to the top. Once these components are separated, the remaining liquid undergoes secondary treatment to further purify the effluent.

Our installation process is comprehensive, covering ground preparation, site inspections, and excavation before the plant is carefully positioned. Domestic STPs are a safe, reliable solution for homes not connected to mains drainage; they promote natural bacterial growth to treat sewage effectively without polluting the local environment.

West Country Drainage Services provides expert advice, guidance, and support for both new installations and ongoing maintenance.

Sewage Treatment Plants Installed

Why are you suffering from one of these issues?

Smells

Bad smells can mean a few different issues, from product use to a problem with the plant.

High water level

This could indicate a problem with the discharge location or your plant, which would require investigation. This could mean your STP is now non-functional and options will need to be looked at.

Blockage

Sometimes the pipes to and from the plant can become blocked. Check out our drain unblocking page. In most circumstances, we can jet these lines clear to save on costly repairs.

Why choose a Sewage Treatment Plant or a Septic Tank?

Self-contained and low maintenance

Once installed, septic tanks operate autonomously without needing constant attention. They require periodic pumping (usually annually, depending on usage and size) to remove solids, but beyond that, their maintenance demands are minimal compared to more complex systems.

Cost-effective for rural homes

For homes located in rural areas where connection to a centralised sewer system may be cost-prohibitive or unavailable, septic tanks provide a cost-effective solution for wastewater treatment and disposal.

Protects public health and the environment

Properly designed and maintained STPs help in reducing the release of pollutants into the environment. By treating the sewage, these plants reduce the risks of waterborne diseases, protect aquatic ecosystems, and ensure that groundwater and surface water sources remain protected.
