PIQUA — The city of Piqua underground utilities division has begun its annual fire hydrant flushing program this week, starting Monday, Sept 16.

Hydrant flushing will take place Mondays through Thursdays between 6:30 a.m. and 4 p.m. The program may take up to four weeks to complete, said a city of Piqua news flash.

The primary purpose of this program is to verify the proper operation of the city’s fire hydrants through periodic inspections, flow testing and preventative maintenance. Secondarily, a pro-active hydrant flushing program is the key to mitigating water quality-related aesthetic problems by removing accumulated iron and manganese mineral deposits from the water line.

Fire hydrant flushing may cause temporary inconveniences such as a reduction in water pressure and aesthetic issues such as discoloration of the drinking water. Discolored water poses no threat to the public’s health, but it will stain laundry and if consumed may have an unpleasant taste. Residents should be certain all discolored water is out of their home’s plumbing and hot water heater prior to laundering clothes or drinking. In the event that clothes become discolored due to the flushing operations, do not place the clothes in the dryer. A commercial fabric rust removal detergent is available from the Piqua Underground Utilities Division at 123 Bridge St.

Although residents may experience some temporary inconveniences, the flushing program is necessary to maintain a good water supply for both firefighting and domestic purposes. Your cooperation with this program is appreciated. If you continue to notice discolored water coming from your fixture, please flush the cold water side for approximately five minutes. If the discoloration persists, please feel free to contact the City of Piqua Underground Utilities Division at 937-778-2018.
