PROJECTS > Projek Memindahkan Air Dari Tasik Ke Sungai Semenyih

Project Background
The Semenyih Treatment Plant draws its raw water from Sg. Semenyih. Flow in the river is regulated by the Semenyih impounding reservoir. During the prolonged drought in 1997, raw water storage in Semenyih impounding reservoir was severely depleted to very critical level and unable to augment the low flow at Sg. Semenyih Intake to enable adequate abstraction for public water supply.

The production of Semenyih Water Treatment Plant was significantly reduced and water rationing was imposed for about 5 months, causing great difficulties and inconveniences to the affected supply area in Klang Valley. In order to augment the raw water deficit at the Semenyih Intake, it was proposed that numerous disused mining ponds (located a short distance downstream of the Sg. Semenyih Intake) be developed and connected in series to act collectively as regulating reservoir/bunded storage to regulate the flow at the Sg. Semenyih Intake. The yield of Sg. Semenyih will be increased by 70 Mld (15 Mgd)

Asia Baru Construction Sdn. Bhd. which is well known and experienced in fast-track water supply projects was chosen to lead the Premier Ayer-Asia Baru Consortium to undertake the project on turnkey basis. The works proposed by the Consortium include :-

a) Development of 3 nos. ex-mining ponds (Pond A, B and C) interlink with canals and pipelines to form bunded storage/regulating reservoirs.

b) Diversion weir at Sg. Langat with a 30m wide X 1.5m high rubber dam.

c) Intake and pumping station at Pond B.

d) 3 nos. 35Mld pumpsets (2 duty & 1 stand-by), associated M&E equipment and telemetry and supervisory control system.

e) 3 km of 1,000mm dia. conveyance pipeline from the proposed intake to upstream of the existing Sg. Semenyih Intake.
Project Information
Client / Owner: Jabatan Bekalan Air Selangor
Consultant: SMHB Sdn. Bhd.
Main Contractor: Premier-Ayer-Asia Baru Consortium
Sub-Contractor: Asia Baru Construction Sdn. Bhd.
Date of Commencement: 31st March 1999
Date of Completion: 31st December 1999
Project Methodology
In view of the urgency of the work which need to be completed and commissioned within five (5) months, the project was awarded on Turnkey basis. Co-ordination and kick-off meetings were held between the Client, Turnkey Contractor, Consultant and M&E Sub-Contractor at the beginning of the project to clarify and highlight the project requirements.

The construction experience of the Contractor, site constraints, requirements by equipment Sub-Contractor were taken into consideration in the design and detailing by the Consultant. Construction drawings were issued in batches in parallel with the progress of physical works at the site.

The Consultant's Resident Engineer was authorized to decide on construction details and make amendment/revision to the drawings at site. Frequence, site meetings were held between the RE, Contractor and Sub-Contractors to ensure work programme was strictly adhered to achieve the target completion date.

After five (5) months of hard work, close co-ordination and co-operation between all parties concerned, the works finally completed and raw water was able to be pumped from the storage ponds to upstream of the Sg. Semenyih Intake.

Another mission accomplished by Asia Baru Construction Sdn. Bhd. to the satisfaction of the Client and our little contribution toward alleviating the water shortage in Klang Valley area.
