Dams

The Sungai Selangor Dam (SSD) and the Sungai Tinggi Dam (STD) are regulating dams located respectively at the riverheads of Sungai Selangor and Sungai Buloh, major tributaries of Sungai Selangor.

SPLASH is tasked to efficiently manage and regulate the water releases from these two dams to enable sustainable storage and to ensure sufficient quantity of raw water in the river to meet the water treatment plants’ requirements and other functional needs.

With the existence of these regulating dams, during rainy season the rain water would be collected and stored in the dams’ reservoirs instead of wastefully flow to the sea. During dry season, the stored water will be released into Sungai Selangor to augment the flow of the river hence preserve the ecosystem of the river.
