For rural or off-grid properties in Kent not connected to the mains drainage system, a sewage treatment plant installation Kent offers an efficient, eco-friendly, and fully compliant solution for managing wastewater. These systems treat waste to a much higher standard than traditional septic tanks, producing cleaner effluent that’s safe for discharge into the environment.
At CJ Groundworks, we provide professional sewage treatment plant installation Kent, ensuring every project meets strict UK environmental and building regulations. This guide explains how sewage treatment plants work, the installation process, costs, and key legal requirements.
1. What Is a Sewage Treatment Plant?
A sewage treatment plant is a self-contained system that biologically and mechanically treats wastewater from homes or commercial premises. Using aeration and filtration, it removes contaminants before safely discharging the treated water into the ground or a watercourse (where permitted).
Main Components:
- Primary settlement chamber: Separates solids from liquids.
- Aeration chamber: Introduces oxygen to support bacteria that break down waste.
- Final settlement chamber: Allows clean effluent to clarify before release.
A properly installed sewage treatment plant in Kent ensures that wastewater treatment complies with Environment Agency standards, protecting your property and the local ecosystem.
