PROJECTS > Design And Construction Of 11.4MLD Capacity Clear Water Tank

Project Background
Planning for water supply to Cyberjaya, Putrajaya and KLIA had been made on the basis that the initial and future ultimate demands will be served by the nearest major source works i.e. Sungai Semenyih Treatment Plant, via the balancing reservoir located within the said treatment plant. Owing to the need to ensure that the water supply to these prime development areas was maintained without disruption under any foreseeable circumstances, an alternative water supply system from different source was required. Towards this end, Sungai Selangor Water Supply Scheme, being the largest scheme serving the Klang Valley was studied and found to be able to supply water to these developments as an alternative source. The study also revealed that standby power generating plant shall be provided to the existing Sungai Semenyih Treatment Plant to enable continuous plant operation and production in the event of power failure.

The scope of works of the project comprised of the following:

> Construction of a Generator Building to house one (1) no. 2.5 MW Diesel Driven Generator Set at the existing Sg. Semenyih Raw Water Intake site.

> Construction of a Generator Building to house two (2) nos. 3.0 MW Diesel Driven Generator Set at the existing Sg. Semenyih Treatment Plant.

> Construction of a 11.4ML capacity Clear Water Tank at the existing Sg. Semenyih Treatment Plant.

> Laying of a 1000mm Diameter mild steel pipeline connecting the existing 1800mm diameter pipeline to the new Clear Water Tank complete with isolating valve and flowmeter.

> Other ancillary and associated works at the existing Sg. Semenyih Raw Water Intake and Treatment Plant sites.

Project Methodology
Due to the urgency to provide alternative water supply to Cyberjaya, Putrajaya and KLIA, the project was awarded by direct negotiation on turnkey basis. This was because the development in the said areas were already at an advanced stage. Immediately upon award of the Project, soil investigation and land survey were carried out to obtain data necessary for detailed engineering design. Construction drawings were issued progressively and upon receipt, construction works commenced immediately, wherever possible. During the initial stage of the implementation, weekly meeting were held between Client, Consultant, Turnkey Contractor and all other works contractors to identify and confirm all the critical activities. This was to ensure that the construction drawings were issued in an agreed prioritised order. The construction experience of the contractors were taken into consideration in the design and detailing.

At the site level, the Consultant's Resident Engineer was fully authorised to decide on construction details and resolved any discrepancies found in the construction drawings. The M&E contractors' representatives were also present at site to ensure that all civil requirements necessary for equipment installation were provided. As the works were carried out within the existing Sg. Semenyih Intake and Treatment Plant, prior permission had to be obtained from the plant operator and any activities which interfaced with the operations of the existing plant were carefully planned and carried out in controlled manner. To minimise interference with the plant operation, some works were carried out during off peak hours or at night.

After fifteen (15) months of hard work, close coordination and cooperation by all parties concerned, all the new works were finally completed and incorporated into the existing system. Shortly after commissioning of the system, the standby power generating plant at raw water intake was put into service due to an incident of TNB power failure. This again demonstrated Asia Baru Construction Sdn. Bhd's. little contribution in helping to alleviate water supply disruption.
