Why will Selangor dam levels stay stable despite dry Southwest Monsoon?

Question

Accepted Answer

Selangor Dams Expected to Maintain Stable Water Levels Despite Dry Spell

Selangor's dam water levels are projected to remain stable throughout the ongoing Southwest Monsoon, with current reserves at over 95 per cent capacity in all seven dams. This stability is attributed to the robust water management strategies in place, including the significant storage capacity of the dams and the development of alternative water sources like the Selangor Off-River Storage Scheme (SORSS) and groundwater. These measures collectively ensure the state's water resources are sufficiently prepared to withstand the dry period, which typically extends until September.
Understanding the Southwest Monsoon's Impact on Rainfall

The Southwest Monsoon, which commenced on May 10 and is anticipated to persist until September, is characterized by meteorological conditions that generally lead to reduced rainfall. This period typically brings lower humidity levels across the region. While the monsoon season itself is a significant weather pattern, its specific impact in Peninsular Malaysia during this phase often results in less precipitation compared to other monsoon periods, such as the Northeast Monsoon.
Strategic Enhancements to Raw Water Storage Capacity

Lembaga Urus Air Selangor (LUAS) has proactively identified and is developing numerous additional ponds and former mining sites situated near major rivers. These locations are being upgraded with essential water supply infrastructure to substantially boost raw water storage capacity. These sites are integrated into the Selangor Off-River Storage Scheme (SORSS), a comprehensive initiative that encompasses over 100 identified ponds and several former mining areas, thereby optimizing the utilization of alternative water sources.
Comprehensive Water Resource Preparedness

The combined readiness of Selangor's water resources, encompassing both the existing dam capacities and the ongoing development of the SORSS, is estimated to provide a safeguard of up to nine months. This extended preparedness is specifically designed to ensure the state can effectively manage its water supply through the duration of the Southwest Monsoon. Furthermore, LUAS is actively maximizing the use of groundwater as a supplementary source to treated water, with a particular focus on meeting the demands of the industrial sector through licensing and abstraction charges, including the establishment of three groundwater wells in Hulu Selangor for dry season usage. The stringent enforcement of the Zero Discharge Policy (ZDP) also plays a critical role in minimizing the pollution of water resources, ensuring that water treatment plant operations have not experienced disruptions due to industrial contamination.
