This project will cover the catchment area of 60.9 sq km stretching from Cheras Batu 11 to Kajang. The 105km sewage pipe network will connect 1174 manholes that integrates 164 small inefficient multipoint sewage treatment plants in various housing area such as Cheras Batu 11, Desa Baiduri, Cheras Jaya, Kajang 1 & Kajang 3, inclusive of Kajang Prison and link it directly into one centralized location that will immediately reduce multipoint of pollutant discharge into the Langat River.
