Pengurusan Air Selangor Sdn Bhd recently announced via a statement shared with World of Buzz that in 2020, average achievement of Non-Revenue Water (NRW) has been successfully lowered to 28.6% compared to the average NRW at the rate of 29.7% for 2019.
In case you’re wondering, NRW is water that has been produced and is “lost” before it reaches the customer. Thus by lowering the rate, this means that more water has been reaching us the past year!
This achievement has exceeded the target at a rate of 29.2% set by the National Water Services Commission (SPAN). Air Selangor achieved this despite the Covid-19 pandemic and the Movement Control Order (MCO). For the year 2020, Air Selangor has spent RM255 million to reduce NRW rates through the implementation of various initiatives, including:
1. Leak specialists (LS) and Leak Inspectors (LI) successfully detected over 90K cases of pipe leakages all over KL, Selangor and Putrajaya. Air Selangor have employed a total of 54 LS officers and 133 LI officers.
2. They launched three programs including the Active Leakage Control program, District Meter Zones Establishment program and the Old Pipes Replacement Program. These programmes reduced broken pipe incidents by 51 per cent since 2017.
3. Air Selangor also fixed 1,650 pressure transient sensors at main pipes to detect leakages at early stages thus making repair works more efficient. The transient pressure can prevent the main pipes from bursting which could cause water supply disruption to consumers.
4. Usage of Permanent Leak Noise Correlating Loggers capable of detecting leaks in the reticulation pipe system each time, 24 hours a day. This online monitoring system allows immediate action to be taken once the data shows available leaks in the pipes.
To further the NRW reduction, Air Selangor has allocated RM293million to be spent in 2021. From that, RM170 million will be used to replace all old pipes and RM16 million to replace old and damaged meters, said Air Selangor chief executive officer, Suhaimi Kamaralzaman.
In line with its success in reducing the NRW rate since 2019, Air Selangor is determined to continue to reduce the NRW rate to 25% in 2025 and then to 15% by 2049. They hope that the public can report immediately if they see or find out incidents of leaking and broken pipes, illegal pipe connections as well meters manipulated by irresponsible people through the Air Selangor at 15300, Air Selangor application, or their official social media website at www.airselangor.com.
