The Langat Sewerage Project is one of the Greater Kuala Lumpur anchored projects under the Ministry of Energy, Technology and Water, implemented by Jabatan Perkhidmatan Pembetungan (JPP). The project involves building a centralized sewage treatment with 920.000 population equivalent (PE).
The project includes laying approximately 105 km of a sewer network having different pipe sizes. I.CO.P. Construction (M) Sdn. Bhd. (I.CO.P.) – appointed as Tunnelling Specialist by MMC PLSB – is building part of the sewerage system by microtunnelling in the project area no. 7 (the entire project amounts to RM1.5b).
The works include the underground installation of sewers with sizes ranging from 225 mm to 1800 mm diameter, in challenging ground conditions.
I.CO.P. has completed a ND1800 mm curved microtunnel, for a total length of 726 m: a record for the country, which is inscribed in the Malaysia Book of Records (MBR). I.CO.P. is currently attempting another record for the longest ND1800 mm sewer laid by microtunnelling in rock, a 515-m long, s-curved ND1800 drive crossing a granite formation having a UCS up to 160 MPa.
