UTILISATION OF ALTERNATIVE WATER RESOURCES FOR DECENTRALISED WATER SOLUTIONS IN THE CITY OF KUALA LUMPUR - NATIONAL WATER INNOVATION CONFERENCE AND EXHIBITION (NWICE 2022)
In current scenarios, Malaysia's water supply is facing water disruption due to a shortage of water resources (quantity and quality) and rapidly increasing water demand due to urbanisation and development. Climate change has seriously affected water scarcity with more frequent dry weather and severe El Nino phenomenon in the last decade. In 2015-2016, Malaysia experienced extreme drought events throughout the states resulting from the El Nino and climate change impacts. These drought events caused water supply shortages due to insufficient water resources. Nine water supply dams have experienced a decline in water storage that reached a critical level (below 40% of dam water storage). Kuala Lumpur has experienced water stress, and will be more significant in the future. In the context of water supply in Kuala Lumpur, almost the entire source of treated water supply depends on Selangor. The primary raw water source is from Klang Gate Dam and Batu Dam, located in the upper Klang River basin with two numbers of Water Treatment Plants (WTP) supplying 190 million litres per day (MLD) for Kuala Lumpur. As for water demand, Kuala Lumpur has increased steadily over these years and grown substantially with the proposed Greater Kuala Lumpur Klang Valley initiative. The projected water demand will increase from 5,500 MLD in 2016 (15% buffer) to 8,612 MLD in 2065. This study focuses on identifying and assessing the water yield (availability) of AWR within Kuala Lumpur to reduce the dependency on surface water. The potential AWR are rainwater, stormwater runoff, floodwater reservoir, groundwater, low flow water, and wastewater as supplementary water supply. The total yield of utilised potential AWR in Kuala Lumpur is 815 MLD which can cater to 81% and 79% of the total water demand in WPKL for 2020 (1,008 MLD) and 2030 (1,035 MLD). The study also will look into the optimisation of the integrated AWR for the development of a decentralised water system as a solution to ensure water supply security and sustainability. Towards becoming a Water Sensitive City, Kuala Lumpur needs to implement Integrated Urban Water Cycle Management (IUWCM) to be more self-sufficient and climate-resilient to prevent the shortage of drinking water supply capacity, particularly during drought.

Abstract
In current scenarios, Malaysia's water supply is facing water disruption due to a shortage of water resources (quantity and quality) and rapidly increasing water demand due to urbanisation and development. Climate change has seriously affected water scarcity with more frequent dry weather and severe El Nino phenomenon in the last decade. In 2015-2016, Malaysia experienced extreme drought events throughout the states resulting from the El Nino and climate change impacts. These drought events caused water supply shortages due to insufficient water resources. Nine water supply dams have experienced a decline in water storage that reached a critical level (below 40% of dam water storage). Kuala Lumpur has experienced water stress, and will be more significant in the future. In the context of water supply in Kuala Lumpur, almost the entire source of treated water supply depends on Selangor. The primary raw water source is from Klang Gate Dam and Batu Dam, located in the upper Klang River basin with two numbers of Water Treatment Plants (WTP) supplying 190 million litres per day (MLD) for Kuala Lumpur. As for water demand, Kuala Lumpur has increased steadily over these years and grown substantially with the proposed Greater Kuala Lumpur Klang Valley initiative. The projected water demand will increase from 5,500 MLD in 2016 (15% buffer) to 8,612 MLD in 2065. This study focuses on identifying and assessing the water yield (availability) of AWR within Kuala Lumpur to reduce the dependency on surface water. The potential AWR are rainwater, stormwater runoff, floodwater reservoir, groundwater, low flow water, and wastewater as supplementary water supply. The total yield of utilised potential AWR in Kuala Lumpur is 815 MLD which can cater to 81% and 79% of the total water demand in WPKL for 2020 (1,008 MLD) and 2030 (1,035 MLD).
