Luas 'too eager' when it comes to water rationing

Published:  |  Modified:

AUDIT REPORT The Selangor Water Management Authority (Luas) appears to be a bit too eager in undertaking water rationing exercises, says the Auditor-General’s Report 2015 (Series 2).

The report said raw water capacities in all seven dams in Selangor between 2014 and 2015 did not reach "critical levels", even during times of drought.

Even at critical levels, the dams could still provide water for 27 to 90 days.

According to the audit, the capacity of each dam, measured in the number of days it can provide water to the state, is as follows: Klang Gates - 131 days; Tasik Subang - 230; Batu - 195; Sungai Langat - 184; Semenyih - 301; Sungai Tinggi - 94; and Sungai Selangor - 124 days.

The audit was conducted based on an analysis of rain data from 2011 to 2015, provided by Luas' Integrated Water Resources Information System (IWRIS).

Luas is responsible for conserving the state's water resources, which includes river basins, ground and surface waters, lakes, ponds, mining pools and coastal waters.

In its reply to the National Audit Department, Luas said it has conducted its own audit of the actual storage capacity of the seven dams and had adopted an intelligent system to manage its resources optimally.

The Auditor-General's Report 2015 also noted that Luas should extend its alternative sources of water, including extending the hybrid off-river aumentation system (Horas) to Klang and the Sungai Langat basins, instead of focusing on Sungai Selangor.

The report also noted that the extraction rate of groundwater was low, relative to the availability of such resources.
