This report covers the testing program undertaken in designing inlet structure or pump sump improvements for the House, Sungai Besar, Selangor. The operations of four pumps on the 1/10th scale physical model for the proposed were tested in Hydrology/Hydraulics Laboratory at Universiti Sains Malaysia, Perak Branch Campus, Seri Iskandar.

Bagan Terap Pumping Station abstracts irrigation water from Sungai Ulu Bernam, Selangor Darul Ehsan. Flow is delivered to irrigation distribution system via a discharge bay structure.

The existing pumping station, commissioned some years ago, is now under capacity and consequently a new pump station is proposed. This will include the replacement of the existing pumps station with higher capacity units and the installation of larger diameter delivery irrigation network. To gauge the effects of the refurbishment, model test study was commissioned.


The proposed pumping station sump will house four Flygt series 7101 pumps, each maximum rated at 1.8 cumecs or 1800 L/s. The pumps will deliver flow via four new 1.2 m diameter discharge pipes into the new discharge structure.
