MMC Pembetungan Langat Sdn Bhd (MMC PLSB), was awarded by the Ministry of Energy, Green Technology and Water (KeTTHA) to embark on a project called the Langat Sewerage Project which consist Centralised Sewage Treatment Plant and Sewerage Conveyance System.
Design and build based on the experience and success of Tokyo Metropolitan Sewerage Service in Japan, the innovative and modern facility will be equipped with green technology initiatives and public facilities and it can accommodate sewage inflow of 207,000m3/day or 920,000 population equivalent (PE), covering a total of 60.9 sq km catchment area starting from Cheras Batu 11 to Kajang. It is designed to achieve the Class 1 water quality, specifically in the ammonia removal.
This project will rationalise 164 local sewage treatment plant in the area of Cheras Batu 11, Desa Baiduri, Cheras Jaya, Kajang 1 & Kajang 3. It will also involve the construction of approximately 105km new sewerage piping network, building six new pumping stations and upgrade four existing pumping stations that will link directly into one centralised location.
The Langat Sewerage Project provides its communities with range of public recreation and amenities such as community hall, landscaped park, badminton and futsal court built above the plant. The project is scheduled to complete in October 2020 and expected to improve the quality of effluent while reducing one of the point sources for the ammonia pollution into the Langat River.
