Sewage Treatment Plant – an FAQ


What is sewage treatment plant?

A sewage treatment plant (STP) is a facility designed to treat wastewater from residential, commercial, and industrial sources. Its primary function is to remove contaminants and pollutants from sewage before it is discharged back into the environment. STPs play a crucial role in protecting public health and environments around Cranleigh, Horsham, Midhurst, Petworth and Pulborough by treating wastewater to a level safe for release into rivers, lakes, or oceans.


How does STP work?

Sewage treatment plant typically employs a series of physical, chemical, and biological processes to treat wastewater. These processes include screening to remove large debris, primary sedimentation to settle out solids, biological treatment to break down organic matter, and finally, secondary sedimentation to separate treated water from remaining solids. Advanced STPs may also incorporate additional treatment stages such as disinfection to remove pathogens before discharge.


How is sewage treatment plant installation conducted?

Installation of an STP involves several steps, including site assessment, design, obtaining necessary permits from local authorities around Cranleigh, Horsham, Midhurst, Petworth and Pulborough, excavation, equipment installation, and commissioning. The process begins with evaluating site conditions, determining the appropriate size and type of plant, and obtaining approvals.

Once approved, the construction phase begins, which includes excavation for tanks, installation of piping, pumps, and other equipment, and connecting the plant to the existing sewer system. Finally, the plant is tested, and adjustments are made to ensure it operates efficiently.
