The massive ongoing sewerage project in Langat, Selangor, has achieved yet another record.
In its most recent feat, the Langat centralised sewage treatment plant (CSTP) has set a new benchmark for the nation’s sewerage industry for tunnelling curvature.
The Langat CSTP project now has the longest micro tunnelling curvature, one of the many important segments that support a total of 105km gravity sewer networks.
It recently saw the successful breakthrough of the micro tunnelling DN1800 curvature sewerage pipeline totalling 725m.
The engineering feat is captured in the Malaysia Book of Records in an event attended by Water, Land and Natural Resources Minister Dr Xavier Jayakumar.
In mid-January, the same project achieved the nine million man-hours without loss time injury mark.
The project, which is an initiative of the ministry, is implemented by the Sewerage Services Department.
MMC Pembentungan Langat Sdn Bhd (MMC PLSB), via a collaboration with the Tokyo Metropolitan Government, is the main contractor entrusted to complete the project.
MMC PLSB is a wholly owned subsidiary of MMC Corp Bhd.
The project, which is expected to reach its full completion in March 2022, is in support of the government’s aspiration to ensure the preservation of Langat River’s water quality, as well as to reduce the burden of contamination on the nearby water treatment plant.
Elaborating on the project, a statement from the Ministry of Water, Land and Natural Resources said the construction methodology is entirely different from the conventional open trench method.
It said the new record was a result of the collaboration between MMC PLSB and its technical partner MMC Engineering Sdn Bhd and tunnelling specialist ICOP Construction (M) Sdn Bhd.
“This approach is the most feasible solution to minimise inconvenience to the public and it was the right decision to resolve problems associated with pipe-laying in urbanised areas. It expedited the construction activities,” it said.
The project is expected to benefit 920,000 populations equivalent to covering approximately 77.6 sq km of catchment area in Cheras and Kajang.
Upon completion, the Langat CSTP, located on a piece of 7.3ha land in Kampung Sungai Balak, will be able to treat raw sewage to Category 1 Standard A effluent as stipulated in the Environmental Quality (Sewerage) Regulation 2009.
