Pressure Check: How One District Cut Leak Costs by Six Figures

A California water district cut repair costs by over $100,000 in one quarter using a sub-$20,000 pressure monitoring system

A small water district in the Los Angeles foothills has found that relatively modest spending on pressure monitoring technology can yield returns that far exceed the investment, offering a model that water utilities nationwide are beginning to study.

Crescenta Valley Water District, which serves communities along the base of the San Gabriel Mountains, had long struggled with leaks traced to aging pipes and uneven pump pressure. Without real-time data, maintenance crews could not anticipate failures before they became expensive emergencies. The district turned to Mueller pressure loggers, deploying the devices across its distribution network to give operators continuous visibility into pressure conditions for the first time.

The data pointed quickly to the source of the problem. Pressure spikes generated during pump operations were stressing older pipe connections and causing repeated failures. Rather than undertaking a broad infrastructure replacement, district officials made targeted operational adjustments: staggered pump scheduling, recalibrated tank levels, and variable frequency drives to smooth fluctuations in the system. The changes, modest in scope, proved sufficient to interrupt the cycle of damage.

Over three months at the close of 2025, the district avoided between $100,000 and $120,000 in repair costs, according to Gabriel Gomez, assistant director of operations. The return, he said, amounted to six or seven times the initial outlay, with payback measured in months. The district also recovered thousands of gallons of water per avoided event, a conservation benefit of particular weight in water-stressed Southern California.

CVWD now plans to add acoustic sensors to fire hydrants in its two highest-risk zones, allowing crews to detect underground leaks before they reach the surface. The sensors are designed for in-house installation, holding costs down. For utilities across the country, which collectively lose vast volumes of treated water to leaks each year, the Crescenta Valley case offers evidence that targeted sensor deployment, rather than wholesale infrastructure overhaul, may represent the more practical near-term path. Whether that model can scale to larger, more complex systems remains an open question.
