The works under this project from part of the works under the scheme for effective utilisation of water supply from Sg. Selangor Phase 3 Bukit Badong source works and strategies for relieving the Sg. Semenyih and Sg. Langat supplies.

Prior to year 2004, demand areas in Pudu Ulu, Cheras Indah, Pandan, Shamelin Perkasa, Dato Keramat AU3 etc. received water supply from Sg. Langat source works. Treated water from Sg. Langat Treatment Plant was pumped to Langat Balancing Reservoir and subsequently gravitated to New Pudu Ulu Reservoir in Cheras area. This New Pudu Ulu Reservoir serves as the storage reservoir supplying the demand areas mentioned above.

Due to the increase in water demand exerted by new housing and commercial developments and commitment of Sg. Langat Treatment Plant to satisfy the consumers located upstream of these areas, a new alternative water supply source is therefore required as the Sg. Langat source works had been stretched to the limit.

Meanwhile, the Sg. Selangor Phase 3 Bukit Badong source works had been completed and surplus water was available for supply to other demand areas. However, the capacity of the existing trunk supply network could only convey the surplus water up to Wangsa Maju area. Therefore, new pumping facility was required to boost the pressure in the system for supplying the surplus water to New Pudu Ulu Reservoir, which is located more than 20 km away from Wangsa Maju. In order to achieve this objective, this project was implemented by Perbadanan Urus Air Selangor Berhad (PUAS), now SYABAS on fast-track basis through invited tender. The contract was awarded to Lebar Daun Construction Sdn Bhd, i.e. the tenderer who submitted the lowest bid. The whole Contract was in turn sub-contracted to Asia Baru Construction Sdn. Bhd.

Briefly, the scope of works for this Contract Package comprises the following major components:
