Project Need :
The site required overflow screening to 6mm and retention of storm flows to maximize storage capacity of the sewerage network and prevent flooding of the down stream sewage treatment works.
Description of Works;
Manor Wood is an existing CSO, situated in a wooded area, and remote from any power supply. The cost to supply a power source was considerable. The site required overflow screening to 6mm and retention of storm flows to maximize storage capacity of the sewerage network and prevent flooding of the down stream sewage treatment works.
This location predominantly suffers from frequent spills. The flow rate of the overflow had to be designed to screen 400l/s to 6mm in two dimensions. Given this information Copa were able to achieve the discharge consent utilising Steinhardts non-powered Hydroclean Brush Screen.
Flow control was achieved with Steinhardts Constant Flow Regulator designed to pass forward a flow rate of 160l/s.
