Technology Category	Sensors - Air Pollution Sensors Sensors - Environmental Sensors
Applicable Industries	Electrical Grids Utilities
Applicable Functions	Logistics & Transportation
Use Cases	Leakage & Flood Monitoring Water Utility Management
Services	System Integration
Challenge	Air Selangor, a large water distribution company in Malaysia, was grappling with a high rate of non-revenue water loss, which stood at 33.3 percent in 2017. The company's aging infrastructure was a concern, and it was keen on reducing leaks and bursts and identifying the causes of pressure surges to mitigate the damaging transients that could reduce the lifespan of its pipes. The company used various techniques to identify leaks and bursts, but the response time was not quick enough to minimize the runtime of leaks/bursts and the disruption caused. The remote geographical location of its trunk main network often led to a long runtime of leaks before discovery. Pressure transients were known to be an issue within the network, but without information on their sources or causes. The company also noticed that leaks often recurred on the same pipelines, causing concern and harming the utility’s reputation. Air Selangor was actively seeking innovative ideas for continuous monitoring to identify leaks and pressure surges earlier, reduce non-revenue water loss, and improve customer relations. Read More
About Customer	Air Selangor is a large water distribution company owned by the Malaysian state of Selangor. The public utility serves a population of 8.4 million residents and manages over 6200 kilometers of trunk mains, ranging from 300mm up to 2200mm, with much of the pipelines located in remote areas of the state. As a national water company, Air Selangor is committed to cost-effectively managing its network and is constantly seeking innovative solutions to improve its services and customer relations.

Solution	Air Selangor partnered with Xylem to develop a long-term, state-wide monitoring program to improve asset reliability and resiliency. This decision intelligence approach included Xylem Vue powered by GoAigua's Leak Localization application, a real-time monitoring solution well suited to help Air Selangor prevent premature asset failure across the system. Leak Localization combines and analyzes analytics from two major leak detection methodologies—pressure transients and hydrophones—to help utilities localize pipe bursts within minutes and detect slowly growing leaks. This automated process, supervised by analysts in a 24/7 monitoring environment, simplifies the analysis, visualization, and interpretation of massive quantities of data and helps repair crews prioritize their response. Leak Localization also provides transient pressure monitoring, a non-invasive and cost-effective way to monitor water networks for the presence of damaging pressure surges. Through its inline detection of pressure transients, the solution helps determine the source of these events and identifies pipes under stress with high likelihood of leakage. This early warning helps manage damaging pressure variations and mitigate the risks associated with premature pipe failure, prolonging the effective life of infrastructure assets.

Impact #1	The monitoring program has been successful in identifying and repairing leaks and bursts. The Air Selangor–Xylem analytic team is identifying 2 leaks per week, with 295 found to date and continuously monitoring for further leaks on its trunk mains, helping Air Selangor achieve its non-revenue water loss targets. This is a significant improvement compared to traditional methods where the same pipelines may not be revisited for months or years. Data from high resolution pressure and acoustic sensors have enabled important insights into the operation of the network and the nature and distribution of leaks on the trunk mains. In addition, the transient pressure monitoring has identified operational issues related to pump changeovers, allowing Air Selangor to implement interventions to prevent premature failure of assets across their system.
