There are some important steps to remember when reopening a building that hasn’t had much use in the past seven weeks of Pennsylvania’s shutdown.

Bradford City Water Authority Executive Director Steve Disney is reminding that water systems need flushed after prolonged lack of use.

“It is very important to think about the water systems inside the various dwellings and facilities,” Disney said. “Places of business, worship, education and more need to have a plan to properly flush their water systems to ensure a fresh supply exists in the various buildings prior to re-opening.

“Prolonged shut downs and closures have allowed water in those systems to sit and become stagnant,” Disney said. “Stagnant or standing water can lead to low or undetectable levels of disinfectant and cause conditions that potentially increase the risk for biofilm-associated bacteria.”

He explained the volume and duration of flushing will need to correspond to the size of the water system and piping.

“Single family dwellings obviously wouldn’t need nearly as much water flushed through their system as a commercial or Industrial sized building would need,” he said. “The goal should be to totally replace all of the water inside the building piping with fresh water.”

This must be done first with the cold water, and then with the hot water.

“Always flush the cold water first and ensure it has run for an adequate amount of time and volume prior to flushing the hot water. Also prior to flushing the hot water, ensure that the cold water supply is running clear and free from any dirt or discoloration. When flushing the hot water, make sure the hot water reaches its maximum temperature,” Disney explained.

The flushing must be done at each point in the system — every sink, shower, faucet and hose bib.

“Flushing may need to occur in segments such as individual rooms, floors, and areas of operation,” he continued. “Places such as schools or other facilities that will continue to remain closed should have a plan to routinely keep the building water supply flushed until they get back to a normal schedule.”

Disney also added, “Any questions or concerns can be addressed by calling the Bradford City Water Authority at 814-362-3004. If needed or requested, Authority personnel will come out and offer additional suggestions and recommendations to anyone needing help.”

The Department of Environmental Protection said to clean faucets, shower heads and other fixtures as well. Inspect and conduct necessary maintenance on mechanical equipment such as water heaters, boilers, storage tanks, backflow prevention devices, etc. using manufacturer’s instructions.
