How the UFR Works

THE PROBLEM: NON-REVENUE WATER

Every water system has to cope with non-revenue water. Main leaks, theft, tank overflows and unmeasured flow through water meters all contribute to a system's non-revenue water problem. According to the American Water Works Association (AWWA), 14% of indoor household usage in North America can be attributed to leaks. As residential water meters aren't designed to register low-flows such as leaks and drips, much of this usage goes un-metered and un-billed. This type of non-revenue water is called "apparent loss" and is valued at the retail water rate. For systems in which waste water is also billed based on water consumption, this apparent loss is valued at the retail rate for water and waste water combined. Apparent losses through residential water meters can add up to millions of dollars annually in non-revenue water and sewer.

THE SOLUTION: UNMEASURED-FLOW REDUCER (UFR)

The UFR captures this low-flow water and forces it through the meter in a way that causes nearly every drop to be registered. Apparent losses are reduced and customers are held accountable for their actual usage.

HOW THE UFR WORKS

The UFR works by changing the way water flows through the meter at low flow rates. At low flow rates there is not enough energy in the flow to activate the water meter. With the UFR installed, the low, linear flows are divided into batches that are forced through the meter at a higher flow rate. These higher flows can now be registered by the water meter, reducing apparent losses and increasing revenue.
At normal household flow rates, the UFR is fully open, allowing water to flow normally with minimal head loss. As flow is reduced, the UFR returns to its operation of batching the water flow.

THE RESULTS

UFR installations can increase the measurement of billable water between as much as five and ten percent. Customers are held accountable for their actual usage and the system's apparent losses are reduced considerably. Customers that are held accountable for their usage are more likely to fix leaks and conserve our most precious resource, clean water.

A.Y. Boosters

Meet the world's most intelligent, yet simple boosting system. Designed to meet virtually all boosting applications – there's a model for your specific needs. Click on the model name below to learn more.
 

Residential

The residential booster can be run in three different modes, based on your boosting needs. In Pressure Mode, the pump starts with pressure drop and stops on low flow. In Flow Mode, the pump starts and stops by sensing flow. In Conservation Mode, the pump only operates during a peak demand, such as when multiple showers, bathtubs, or irrigation systems are running.

No-Lead Brass

In January 2011, the Reduction of Lead in Drinking Water Act was signed into law, which reduced the allowable lead content of wetted surfaces in drinking water pipes, pipe fittings, and plumbing fixtures as of January 4, 2014. To ensure our customers bottom lines weren't impacted negatively by this transition to no-lead brass, A.Y. McDonald Mfg. Co. launched a microsite with the reference materials below. Although this full site is no longer necessary, we remain committed to educating and assisting our customers. For this reason, we are providing the reference materials and resources regarding the no-lead legislation and transition below. For further information, please contact your sales representative or our factory at 1-800-292-2737.
