Customers in north Chapel Hill and Carrboro may notice water discoloration and pressure changes due to testing

On Wednesday, November 13th, OWASA customers in a northern area of Chapel Hill and Carrboro may notice pressure changes and/or discoloration of water due to operation of special pumps and testing of water flows at some hydrants. A map of the affected area is below.

The testing is part of OWASA’s preparations for cleaning, painting and other work which may start later in November on a water tank west of Piney Mountain Road and Emily Road in Chapel Hill.

The pumps will maintain adequate water pressure and water supply for residential and business uses and fire protection during work on the tank this fall and in the future when the tank needs to be drained for maintenance, etc.

Water discoloration, which can result from stirring up iron particles that have settled in water pipes, may appear in drinking water for a few days after various kinds of work on OWASA’s water system including the testing. The discoloration does not mean the water is unsafe to drink, but OWASA encourages customers not to use discolored water in laundry, preparing food, etc.

Customers who notice discoloration are asked to run cold water from a faucet or spigot for 5 to 10 minutes. If this does not clear up the water, please call OWASA at 919-968-4421.

The water discoloration may also appear in the ice in ice makers. Customers can use discolored ice to water plants, etc.

The map below shows the area where customers may notice pressure changes or discoloration.
