Sungai Sarawak Regulation Scheme

The Sungai Sarawak Regulation Scheme (acronym SSRS) is a major civil engineering project in Kuching, Sarawak, Malaysia. This project incorporates a 3-in-1 infrastructure (barrage, shiplock and bridge) which is the first of its kind in Southeast Asia.
History.
The Sungai Sarawak basin area experience floods as a result of heavy rainfall from upstream, king tides, poor drainage, or a combination of these factors. In low-lying residential areas, floods occur every 1st and 15th day of the lunar calendar.
Design.
The SSRS consists of:
Construction.
The construction of the SSRS is divided into three phases,
Phase I.
Phase I of the SSRS project is the construction of the Bako Causeway, the first causeway in Sarawak. The construction involved creating a rock-filled closure across Loba Santubong on Jalan Bako and was completed in August 1993.
Phase II.
Phase II of the SSRS project is the construction of the main Barrage Facility (Kuching Barrage and Shiplock), comprising:
The groundbreaking ceremony of the Barrage, Shiplock and Bridge was held on 25 July 1995 and graced by Abdul Taib Mahmud, the Chief Minister of Sarawak.
Phase III.
The components of Phase III of the SSRS project are:
The rainfall and water telemetry stations were installed at the following locations:
Phases II and III were constructed simultaneously and was completed in November 1997 at a cost of RM150 million.
The Kuching Barrage and Shiplock was officiated by Mahathir bin Mohamad, Prime Minister of Malaysia.
Operation of Kuching Barrage and Shiplock.
The barrage and shiplock is managed and operated by Kuching Barrage Management Sdn. Bhd., under the supervision of the Sarawak Rivers Board and is governed by "The Sarawak Rivers (Sungai Sarawak Barrage) Regulations 1997", which states as follows:
Real-time water and rainfall data is collected by the telemetry system and based on computational model of the Sarawak River. The predicted discharge and water level are the two main factors in deciding when to operate the barrage gates. All data collection and information will be processed by a sophisticated river analysis software known as MIKE-II.
