The City of Highwood will begin its annual water valve exercising program Monday, May 5, and will continue through Saturday, May 31, 2014. Valve exercising may remove the naturally occurring minerals and sediments that are stripped from the walls of water pipes and valves during this procedure. The velocity of the water and the change in flow direction cause minerals and sediments that may result in discolored water.
While the water is safe for cleaning, hand washing and bathing, officials recommend the discolored water not be used for cooking or drinking as a precaution until the water in your household faucets run clear. Customers are also advised not to wash clothing with the discolored water because it may cause stains. Because the water system will remain under pressure at all times a boil advisory will not be issued as there is no threat of contamination.
Customers are reminded hot water heaters store water and if discolored water has entered the tank, it may take the hot water longer to return to normal. In addition to the large scale pipe flushing efforts run by water resources crews, customers experiencing discolored water may consider running faucets for a short period of time to rid pipes of discolored water. Customers are also encouraged to check residential filters and faucet screens for sediments. In many cases this is simple and involves unscrewing the screen at the head of a faucet.
Once water color returns to normal it is safe for all uses.
Should you have any questions regarding this matter please contact Jeff Harding, Director of Water Treatment at 847.432.3730
