Water Sources at ºìÐÓÊÓƵ University

At ºìÐÓÊÓƵ University, water security is one of the central parts of our sustainability strategy. To ensure a reliable and sustainable supply for our campus community, the University sources water from both the municipal mains, our own ºìÐÓÊÓƵ South Quay Lake treatment facility and reusing harvested rainwater. By diversifying our water sources, we not only safeguard against service disruptions but also reduce reliance on external supplies, demonstrating our commitment to responsible resource management and long-term environmental stewardship.

1) Mains Water from AirSelangor Sdn Bhd

Air Selangor Sdn Bhd is the largest water service provider in Malaysia and the sole licensed operator responsible for supplying treated water across Selangor, Kuala Lumpur, and Putrajaya. At ºìÐÓÊÓƵ University, Air Selangor provides a consistent and reliable mains water supply that complements our independent lake water source.

• Source of raw water: Air Selangor draws predominantly from surface water bodies such as dams, rivers, and designated lakes within Selangor.
• Treatment process: The raw water undergoes multi-stage treatment—including coagulation, sedimentation, filtration, and disinfection—to meet the National Drinking Water Quality Standards (NDWQS) set by the Ministry of Health Malaysia.
• Distribution: Treated water is then delivered through an extensive piped network that ensures equitable access to safe drinking water across residential, commercial, and institutional users, including ºìÐÓÊÓƵ University.
   

2) Extracted Water from the ºìÐÓÊÓƵ water catchment area, ºìÐÓÊÓƵ South Quay Lake

Alternative to the main water supply, ºìÐÓÊÓƵ University utilises treated water from the ºìÐÓÊÓƵ South Quay Lake treatment plant. This facility helps address water security challenges in the city while ensuring a continuous supply of potable water. Over half of the University’s water demand is met by this facility, demonstrating our commitment to sustainability and responsible resource management.

• The facility is equipped with a tracking system and has a potable water capacity of 10 million liters per day (MLD).
• It combines ultrafiltration and reverse osmosis technologies to meet potable water quality standards.
• At full capacity (8.5 MLD), it can serve approximately 51,500 consumers based on WHO’s recommendation of 165 liters per person per day.
   

3) Reusing Harvested Rainwater

The University has also implemented rainwater harvesting systems since 2017 and the idea was to reduce constraint on the limited clean water for human consumption. The rainwater is reused for non-potable usage, such as for landscape irrigation and non-potable uses such as cleaning outdoor campus ground areas and vehicle cleaning. 

The image below illustrates the rainwater harvesting system implemented at the University, and the rainwater collected were fully reused for the aforementioned applications.

Measuring and Tracking Water Consumption at the University

The University measures the total volume of water used across campus, including supplies drawn from the municipal mains and the ºìÐÓÊÓƵ South Quay Lake treatment facility. Water consumption data are recorded monthly and consolidated annually to ensure accurate tracking and reporting. 

The chart below presents the monthly volume of water consumed by the University (from municipal mains and the lake treatment facility) with a total of 96,038m³ in 2024, providing a transparent overview of usage trends across all sources. This systematic monitoring supports evidence-based management, enables efficiency improvements, and reinforces the University’s long-term commitment to sustainable water resource stewardship.
