In order to proactively address the ongoing challenge of apparent water loss and make intelligent decisions regarding rates and capital expenditures, Clayton County Water Authority (CCWA) engaged Xylem to evaluate their entire metering operation.
As one of Georgia’s smallest counties in terms of land size area (only 143 square miles), Clayton County’s location near the top of a regional watershed means it has little area to gather precipitation into streams and rivers. With limited water supplies available in its own catchment area, CCWA is increasingly recognized as an industry leader for proactive water management approaches. Recently CCWA demonstrated this proactive mindset by instituting a program that would harness the power of data analytics to achieve benefits such as increased revenue, better customer care and wiser capital spending — all by targeting an invisible source of system leakage: apparent water loss.
Located in a state with some of the strictest efficiency and water conservation regulations in the country and a growing population, CCWA has been addressing water loss across its entire system. Apparent water loss (defined as water that is consumed, but not properly measured, accounted for or paid for) is a significant source of revenue leakage for many utilities. On average, about 5 percent of retail water is not registered at the meter, or unbilled for, representing approximately 2 percent of a utility’s top-line revenue.
In looking for an innovative solution to address these issues, CCWA was open to exploring new solutions using intelligent monitoring and management tools that allow them to undertake a prioritized, economically-justified meter replacement program. They refused to follow the status quo of random or time-based meter replacement and instead were driven to identify customer metering accuracies, quantify the apparent water loss and improve operational efficiencies — all without raising rates.
