The residents of Bandar Rinching including its surrounding vicinities and the commercial/industrial areas of Beranang in the District of Hulu Langat had been experiencing shortages of water supply. This had been the case for quite some times due to insufficient water pressure and partly because of its faraway locations where they are at the tail end of the existing supply line from Sg. Langat and Sg. Cheras Water Treatment Plant.

The prolong water shortages were so bad that temporary storage tanks were put up by Perbadanan Urus Air Selangor Berhad (PUAS) and supplies were brought in by tankers as temporary relief. These measures too proved rather irregular which caused untold inconveniences to the users/residents. Their woes and plights were highlighted by the print media in October 2003 and PUAS on its part promised swift action.

In the light of the above, Asia Baru Construction Sdn. Bhd (ABC) submitted a proposal to PUAS entitled “Proposed Laying of 450mm Fid MSCL Pipe from Bangi Lama Reservoir to Pekan Semenyih” in late October 2003. In the said proposal, ABC proposes to utilise the water supply from Semenyih Water Treatment Plant by way of interconnecting the existing 1100mm dia. and 600mm dia. pipe already supplying to Bangi Lama Reservoir and Bandar Makota Bangi respectively. In addition to this interconnecting work, a new 450mm dia. pipe of approximately 10.7 km was proposed to be laid along the old Bangi-Semeyih Road and connect to the existing 700mm diameter pipe at Semenyih Town, which in turn will augment the supply to the demand centres in Rinching/Beranang and Tasik Kesuma areas.

The technical and financial proposal by ABC was duly discussed by the PUAS’s Committee in early November 2003 and the Letter of Acceptance was issued to ABC on 10th November 2003. The date of possession of Site was stipulated to be on 24th November 2003 and completion date on 23rd January 2004 i.e. a completion period of 2 months.

Briefly, the Scope of Works for this project comprises the following major components:

  1. Carrying out engineering survey and the design of the proposed 450mm dia. MSCL pipe.
  2. Laying, testing and commissioning of the proposed 450mm dia. MSCL pipeline from Bangi Lama Reservoir to Pekan Semenyih of approximately 10.7 km.
  3. Interconnection of existing 1100mm dia. and 600mm dia. pipe with the proposed 450mm dia. pipe at Bangi Lama Reservoir using hot tapping method.
  4. Connection work of existing 700mm dia. pipe with the proposed 450mm dia. pipe using hot tapping method at Semenyih Town including incorporating a 700mm dia. isolating BV upstream of the connection works.
  5. Supply of related materials and construction of associated civil works.
