Ministry of Environment and Water

2018 – After 14th Malaysia General Election, the component of Ministry of Natural Resources and Environment (NRE) was restructured to form Ministry of Environment and Water


Jabatan Perkhidmatan Pembetungan (JPP) was established on March 1, 1994 to focus on projects implementation and provide technical advices to Ministry of Environment and Water in sewerage-related issues. Under the provision of RMK-9 for Sabah and Sarawak, JPP has been appointed to give advice on sewerage technical matters, to conduct technical audits, and to verify the loan payments from the Federal Goverment to the states.  As one of the government's technical agencies,  JPP has strengthened its management and system administration by making comprehensive rearrangements and restructuring to improve its ability to manage more sewerage projects in the future.


Innovative Plant, Equipped with Green Technologies & Public Facilities MMC Pembetungan Langat Sdn Bhd (MMC PLSB), was awarded by the Ministry of Environment and Water to embark on a project called the Langat Sewerage Project which consists of Centralised Sewerage Treatment Plant and Sewerage Conveyance System.

Designed and built 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 that can accommodate sewerage 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 Standard A water quality, specifically in the ammonia removal.

This project will rationalise 164 local sewerage treatment plant in the area of Cheras Batu 11, Desa Baiduri, Cheras Jaya, Kajang 1 and Kajang 3. It will also involve the construction of approximately 105km new sewerage piping network, building of six new pumping stations and upgrade of four existing pumping stations that directly be linked 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 courts built above the plant. The project is scheduled to complete in October 2021 and expected to improve the quality of effluent while reducing one of the point sources of ammonia pollution into the Langat River.


Gabungan AJP - MFA is the Project Management Consultant, assisting JPP in managing the project by reviewing the contractor's proposal and monitoring the construction of the project to comply to the Government Needs Statements and Specifications.
