Water System Flushing_Week of 041017 

The Public Works Department would like to take this opportunity to provide a general overview of the Water Distribution Flushing Program and the impact it will have on your water service.

What is water system flushing, and why is it important?
The Water Distribution System Flushing Program is a program designed to “scour and clean” the City’s 106+ miles of water distribution pipes.  The flushing is performed segment by segment throughout the City until all segments have been reached.

The pipe scour/cleaning is achieved by controlling the flow of water through isolated sections of water pipeline at a higher than normal velocity. This is achieved by closing and/or opening specific water valves and releasing water through a fire hydrant. The increased water flow provides a scouring affect to remove settled out debris such as sand, mineral deposits and other material that accumulate in the City’s water pipes. This year, the City is proud to use a new technique to complete the distribution system flushing which minimizes water waste. This is completed by allowing water to flow through a filtration system to remove the settled debris before it is returned to the distribution system.

How will it affect your water service?
While there are many long term benefits to system flushing, there may be some short term inconveniences associated with the maintenance program. Properties in the immediate area may experience temporary water pressure fluctuations and possible discoloration. The discoloration is caused by minerals, sand, rust, and other particulates being disturbed by the high velocity water flow. If you experience discolored water, we ask that you flush the cold water lines in your home or property by opening a hose bib or bath tub faucet for a few minutes until the water clears. Keep in mind that most kitchen and bathroom faucets have screens or filters built into them and may require cleaning if debris is present. As Public Works continues with the flushing program, each subsequent flushing maintenance will present fewer and fewer concerns and begin to establish tremendous value as a preventative maintenance program.

When will flushing take place?
We will be in your area April 10 – May 12th. Water Distribution System Flushing has been divided into manageable areas. The length of time flushing will last in a particular area will depend on the conditions of water mains and in that particular area.

What about water conservation?

The City of Manhattan Beach Public Works Department continues to implement and enforce the Stage 3 Water Conservation Requirements of the City’s Water Conservation Ordinance and thanks the community for their committed efforts. We also ask for your patience in understanding that while we remain committed to water conservation, flushing the distribution system is an essential component of system maintenance and an absolute necessity in our commitment to providing high-quality potable water
