What is a Sewage Treatment System?

A sewage treatment system for private properties processes wastewater from homes and businesses that are not connected to mains drainage. It removes solids, organic matter, and harmful bacteria through physical, chemical, and biological treatments, ensuring that the treated effluent meets environmental standards. Typically housed in a sewage treatment plant, these systems allow safe discharge into natural water sources, helping to prevent water pollution and comply with regulations for off-mains drainage solutions.

How do Sewage Treatment Systems work?

Sewage treatment systems use a combination of mechanical and biological processes to remove contaminants, solid waste, organic matter, pathogens, grease, and oil from sewage water and industrial wastewater. Once treated, the resulting effluent meets the required quality standards for safe discharge into natural watercourses. Common treatment methods include rotating biological contactors (RBC), aeration, sedimentation, and filtration.


There are many treatment system designs, but we only supply BS EN-certified systems that comply with industry regulations and come from trusted manufacturers known for reliable performance and excellent customer service.
