INNOVATIVE TECHNOLOGY IN WASTE WATER TREATMENT FOR ENVIRONMENTAL EFFICIENCIES

Langat Sewerage Project is one of the “Sewerage Non River” projects under Greater Kuala Lumpur.  Anchored under the Ministry of Water, Land, and Natural Resources (KATS). Fully implemented by Jabatan Perkhidmatan Pembetungan (JPP), the high-impact project involves building a centralized sewage treatment plant with 920,000 P.E equivalent to 207,000m3/day and laying sewage piping network of approximately 105km in total.
 
 
This project will cover the catchment area of 60.9km2 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, including of Kajang Prison and link it directly into one centralized location that will immediately reduce multipoint of pollutant discharge into the Langat River.

Once completed, sewage within the Langat Catchment will be treated to Category 1 Standard A as per stipulated in the Environmental Quality Act (Sewerage) 2009.

 
The innovative and modern facility will be equipped with green technology initiatives and public facilities which can accommodate sewage inflow of 207,000 m3/day or 920,000 population equivalent (PE), covering a total of 60.9 sq km catchment area starting from Cheras Batu 11 to Kajang.

LANGAT SEWERAGE PROJECT is aware that the construction of the SEWERAGE NETWORK may result in some unintended consequences such as traffic disruption and environmental impacts like noise pollution.

An extensive traffic and environment management programme has been put in place to ensure that the construction will only cause minimal amount of disruption.

 

A number of safeguards will be put in place near the construction site to ensure the safety of site workers and the general public, as well as to minimise inconvenience during construction. At some of these locations, traffic may be diverted or the roads being closed to ensure general safety in the area.
