How Long Will the Repairs Take?

While DOW crews make every effort to restore water service as quickly and  as safely as possible, it is difficult to estimate when service will be restored due to unforeseen issues and necessary water system adjustments.

a

Why is My Water Cloudy?

After a service outage, water may appear cloudy due to tiny air bubbles that are released after being trapped in the water pipes, much like air bubbles seen in a bottle of soda when you first open it. This water is perfectly safe to drink. If you allow the water to sit for a few moments, the cloudiness will slowly dissipate.

a

Why is My Water Brown?

After a service outage, water may appear brown due to the disturbance of pipeline sediments in the water main, that may have occurred during the pipeline repair work. Running the faucet or outside hose bib for five minutes will flush the lines, and usually addresses the issue. If the issue persists, call DOW to report it.

a

Why is My Water Pressure Low?

This may be caused by a leak on your property or you may have a pressure reducing valve installed on your house that has failed. Another cause may be a leak on the County’s water line, or a fault with the County’s pressure reducing valve, these problems would cause your neighbors to experience pressure loss also. Please call operations at (808) 245-5444 with any questions.
