Prior to this Project, the water supply to the Kuala Lumpur International Airport (KLIA) which was supplied from the Semenyih Water Treatment Plant had been found to be at risk of disruption. In recognition of this vulnerability, the Federal Government of Malaysia has initiated an alternative water supply scheme to support the existing and future water demands at KLIA and the surrounding areas.

An open tender was called for Construction of Sg. Labu Dam by Jabatan Bekalan Air of Kementerian Tenaga, Teknologi Hijau Dan Air Malaysia and Asia Baru Construction Sdn Bhd was successful in its bid and was awarded the Contract. Briefly, the scope of works under the Contract comprised the following major components:

River gate, river intake pumping station and associated ancillary works located about 1.6km downstream of the Sg. Chinchang and Sg. Labu confluence. The nominal pumping capacity is 140 Mld with 4 nos. duty and 2 nos. standby pumpsets.
A 30m high earth fill dam and associated ancillary structures including 3 saddle dams. The total volume of the dam embankment is about 2.0 MCM. The gross reservoir storage capacity is about 9 MCM and cover a lake area of about 70ha.
Approximately 1.0km long 1200mm diameter raw water pumping main from river intake to the dam, which serves as an off-river storage.

The Contract was to construct all the civil and structural works as well as design, fabrication, supply, installation, testing and commissioning of the pumping system and all associated mechanical, electrical, instrumentation and control system under the Contract. Upon completion of all the works, the Contractor continue to operate the pumping system to fill the storage reservoir until the top water level.
