The COVID-19 pandemic has left many businesses, schools, homes, and other buildings unused for weeks. Before people return to these structures, the water needs to be refreshed.

Under normal use, water pipes maintain a chlorine residual that protects public health and aesthetic water quality. Water that sits for a few weeks becomes stagnant.

If you are reopening a closed building, Irvine Ranch Water District recommends you take the following steps:

  1. Identify all water taps, toilets, shower and bathtub fixtures, refrigerator/freezers with an ice maker or water supply, drinking fountains, and any other source of potable water.
  2. Turn on all the water taps with drains simultaneously for 10-15 minutes. (Make sure to check that each drain is working properly).
  3. While the taps are running with fresh water, flush each toilet to refresh its tank and bowl.
  4. Dump any old ice in the refrigerator/freezer and continue to remove the new ice for 3-5 cycles. Run the water from the refrigerator dispenser to refill the water line to the refrigerator.
  5. If the hot water has a sulfur smell or other odor, consider draining your water heater before use. (Follow manufacturers' directions carefully for safety and protection from water damage.)

Don't forget to check that all water taps have been turned off after flushing.

With these simple steps, you can easily restore fresh water to your building.

IRWD's water supply has continued to meet all state and federal requirements to ensure safe drinking water for our community.
