At First Choice modern sewage treatment plants are rapidly replacing septic tanks as a much more environmentally responsible and long-term solution. That’s because sewage treatment plants actively harness natural processes, such as aerobic bacterial digestion, to help break down and neutralise sewage.
Understanding Sewage Treatment Plants
A – Wastewater and sewage from the property is fed through to the treatment plant.
B – The treatment plant allows the solids to settle out and actively treats the sewage via an aerobic (oxygen-dependent) process, breaking it down.
C – The resulting effluent, which is typically 95% clean, can be discharged into a nearby ditch, stream, river, lake or land drain system, subject to appropriate approvals.

Key elements of a sewage treatment plant
The compact, below-ground sewage treatment plant depicted in this cutaway illustration is a watertight enclosure designed to allow solids in the sewage to settle and decompose via an aerobic (oxygen-assisted) biological action.
- Coarse solids are screened out and retained for gradual breakdown
- The screened ‘liquor’ is continuously distributed over plastic media by an airlift pump operated by an electric blower sited a little distance away. This maximises the natural aerobic process
- Subject to relevant official consents, the resulting effluent, which is remarkably clean, can be dispersed into a watercourse or suitable ground soak away
Sewage treatment plants are typically of GRP (glass-reinforced plastic) construction. We use fully certified systems from Titan and Klargester — the UK’s leading suppliers of wastewater treatment systems
