WSO uncovers where you’re losing water. After all, you can’t fix your system if you don’t know what’s broken.

Water Loss Analysis

Water loss control program design to guide cost-effective loss recovery.

AWWA Water Audit Compilation & Validation

The AWWA water audit is our bread and butter, and we wrote the book on water audit validation. We can work with you to compile a water audit and then validate the data and results to make sure the insight the water audit provides is accurate. Our validation meets the regulatory standards in California, Georgia, and Hawaii.

Real Loss Component Analysis

A component analysis breaks down your volume of water loss into meaningful categories that help you make smarter decisions about how to recover it. This is the next step after a water audit, and we know it through and through because we built the industry-standard tool for the job.

Economic Level of Leakage Analysis

Water loss is expensive, but water loss control also costs money. We can help you find a cost-effective balance, the economic level of leakage, where your total costs are minimized. We can then support you in scheduling and executing water loss interventions with an eye toward your bottom line.

Customer Meter Test Analysis

Testing customer meters can serve a variety of purposes - maintaining revenue, reducing risk, planning meter replacement, even justifying metering technology upgrades. As a result, it’s important to match your meter testing program to the insight you want to gain. We can help you design a small and large customer meter testing program that provides insight into performance and supports other meter management goals you may have.

Regional Program Development

Water loss control is a vital element of all agencies’ infrastructure maintenance and supply stewardship programs. Because infrastructure and supply are often regionally shared, water loss control is often easier when an entire region takes it on. We’re the pioneers when it comes to regional water loss control efforts. Our regional programs focus on shared services, learning opportunities, and cooperative research, and we make an effort to identify external funding for regional programs.

Field Services

Dealing with leakage from the ground up while keeping an eye on critical instruments.

Leak Detection

We’ve surveyed thousands of miles of mains in dozens of systems using state-of-the-art acoustic leak detection equipment. Our expert team finds hidden leaks so you can deliver water to customers instead of losing it to leakage. We’ll also help you estimate savings and contextualize your leak detection results using your water audit and infrastructure characteristics.

District Metered Areas

We can set up discrete, metered zones in your system so you know where your infrastructure is leaking, how much you’re losing, and if the losses are worsening. With zonal monitoring, you can deploy leak detection crews right away and to the right place when new leaks start.

Pressure Management

Excessive pressures cause more main breaks, more leakage, and more frequent pipe replacement. Fortunately, we can help you balance service and infrastructure pressure needs. We start by surveying pressures in the field to collect real data on the state of your pressures, particularly when it comes to pressure transients. We can then identify regulating infrastructure that isn’t working ideally, areas that are over-pressurized, and your average system pressure for use in the water audit.

Source Meter Testing

Source meters are essential assets when it comes to understanding distribution system efficiency, so their accuracy is critical. To study source meter accuracy, we can design and conduct a volumetric meter test with you that accommodates your operational and infrastructure constraints. We always aim to produce a replicable test procedure so that future testing is easy.
