Reduce System Losses
Reduce non-revenue water in a comprehensive, cost-effective way
The global issue of non-revenue water (NRW) is becoming an urgent priority for our sector as water scarcity, regulation, and increasingly stringent targets call for tighter control of water from source to tap. The need for proven and cost-effective solutions to identify and mitigate sources of system loss, both real and apparent, couldn't be greater.
The Power of Decision Intelligence delivers new standards of practice that combine remote sensing, real-time continuous monitoring, the targeted use of high-resolution inspection tools, and advance analytics to reduce real and apparent losses to economic levels. In addition to these approaches, modern tools include:
Taken together, the following approaches enable a comprehensive, cost-effective strategy that can help utilities gain control of leakage with significant operational, financial and community benefits.
Modern tools include:
- Advanced Metering Infrastructure to provide high-resolution consumption data in real time
- Advanced data analytics applied to metering data to identify and reduce “apparent losses,” including revenue lost from meter inaccuracy
- “Virtual” District Metered Areas (vDMAs) that monitor network regions using real-time, connected flow meters to establish water balance without hydraulic disruption
- Continuous, multi-parameter monitoring of the distribution network with high-frequency pressure transient and acoustic sensors supported by real-time data analytics to predict, identify, characterize and locate leak and burst events
- Targeted use of high-resolution inline inspection tools that can identify both large and small leaks and pinpoint leak locations with a very high degree of accuracy and efficiency
- Pressure management to reduce leakage rates
Real World Success Stories
Driven to improve operational efficiencies without raising rates, Clayton County, GA embraced a data-driven approach to quantify their water balance and gain a better understanding of apparent losses.
After becoming concerned with ongoing apparent water loss, an Orange County, CA utility used cloud-based analytics to identify meter and data handling inaccuracies and stop revenue loss.
To better understand the condition of their buried pipeline network and proactively address potential water loss issues, Park City, Utah utilized acoustic and transient pressure monitoring.
Perplexed by unanticipated leakage within their distribution network, Tuas Power in Singapore utilized transient pressure monitoring to detect harmful transients and reduce pressure surges.
