During the testing 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.
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 water faucets until discoloration is gone. Residents should refrain from using washing machines during the hours of testing and to run their washing machines while empty for approximately half a cycle after flushing is complete to avoid staining fabrics.
