The Puchong sewerage catchment is located under 3 local authorities, Dewan Bandaraya Kuala Lumpur (DBKL), Masjis Bandaraya Petaling Jaya and Majlis Perbandaran Subang Jaya. The total area for Puchong Sewerage Catchment is about approximately 3900 hectare. The catchment is drained by number of relatively small rivers which discharge into Sungai Kelang. The terrain within the study area varies in different location with some area rolling to undulating and some area generally flat. The projected ultimate Population Equivalent (P.E) of this catchment is about 800,000 P.E until year 2035.
In Puchong sewerage catchment, there are two (2) regional plants which are KLR 142 and KLR 336 located at Taman Mawar, Puchong. The KLR 142 is the old plant taken over from DBKL and will be upgraded to additional design capacity 300,000 PE under Package B31.
This project under Package D52 forms part of the works proposed under the Greater KL initiatives to be implemented by Jabatan Perkhidmatan Pembetungan, Kementerian Tenaga, Teknologi Hijau dan Air (KETTHA).
The works for this package is design & build of sewerage rationalization works at Puchong catchment area including rationalization of 32 multi point sewerage treatment plant including 14 government premises, decommission the rationalised sewerage treatment plants, construct of 38KM sewerage pipeline by trenchless and open cut method .
The aim of this project are:
• To establish a new and effective sewage rationalization works at Puchong which will reduces the polution loading into the receiving water courses.
• To reduce the bad odour and buffer issue faced by residence.
• Establishing green areas through the rationalization of the old treatment plants.
• To establish a new sewerage system which is cost effective in terms of operational and maintenance wise.
