American Water to Perform Hydrant Flow Testing Published May 26, 2026 Civil Engineering Group WRIGHT-PATTERSON AIR FORCE BASE, OH -- American Water will be performing annual hydrant flushing and inspections over the next few months on WPAFB. Testing will take place from 8 a.m. to 5 p.m. starting in May. The inspections and tests are required to determine the proper operation of the fire hydrants for firefighting. Additionally, it is desirable to periodically flush out the lines to ensure water freshness and remove sediment that may be present. Moreover, the annual flushing allows crews to visually inspect and operate hydrants to assess functionality. During the flushing period, motorists should be on the lookout for American Water personnel operating hydrants and walking near the roadway. Drivers should be careful not to drive or park too close to any hydrant if they observe testing in the vicinity. Some slight water discoloration and lower pressure can be expected during the flushing period. Water discoloration caused by the natural sediment being stirred up in the water mains may appear, presenting a cloudiness or rusty appearance. This sediment may be minimized by running cold water through the faucets until discoloration is gone. Check for discolored water before using washing machine or dishwasher. Note: If your laundry becomes stained, DO NOT USE BLEACH OR PUT YOUR LAUNDRY IN THE DRYER. Rewash clothes immediately using more detergent or a heavy-duty detergent and add rust remover. Most rust removers can also be used on stained fixtures. For more information call American Water Customer Service at (937)-623-9786 during normal duty hours.
