Water Main Flushing Program

 

THE 2010 FLUSHING PROGRAM HAS BEEN COMPLETED

CITY CREWS TO BEGIN FLUSHING

WATER MAIN DISTRIBUTION SYSTEM

Daly City - Routine flushing of Daly City’s water main distribution system to improve water quality began July 12, 2010, and was completed by the end of April 2011.  The flushing process removes sediment and mineral deposits through the opening and closing of system valves and discharged through fire hydrants.  Residents may have noticed water running down the street during this operation, and it is not a cause for alarm.  It took approximately one hour for crews to flush one city block, and residents within schedule neighborhoods received advance notice when their street is scheduled.

 

While flushing is taking place in the neighborhoods, residents are advised to take precautions to avoid the potential for discolored water entering household plumbing systems by minimizing water usage. In particular, residents should avoid washing clothes until the evening hours in order to prevent possible staining.

 

To alleviate the impacts of discolored water, residents are advised to initially run only the cold water at the tap, preferably in a bathtub.  If discoloration is observed, water users should let the cold water run for several additional minutes until it clears.  For conservation purposes, the discolored water can be saved for watering plants with no harmful effects.  The discoloration results from naturally occurring sediment and mineral deposits and while aesthetically unpleasant, it is not a health hazard.  Residents may also experience cloudy or milky water created by air bubbles when opening and closing water valves.  If running cold water does not clear the problem after 10 minutes, residents are encouraged to notify the Daly City Department of Water and Wastewater Resources at (650) 991-8200 and a water system operator will be dispatched to provide further assistance.
