City of Martinez Public Works will conduct water hydrant flushing beginning December 9, 2019. The process will be performed daily, between 1:30 p.m. and 3:30 p.m. and will continue until all water mains throughout our water systems have been flushed.
Why Is Flushing Needed?To improve quality and minimize discoloration of the drinking water, caused by sediments in the pipes.
How Will Flushing Affect Water Service?
When flushing crews are working close to your residence or business, you may experience short periods of low pressure. Water outages are not anticipated.
Flushing operations may also lead to discolored water, which can be drawn into homes and businesses if the water is being used during or immediately following the flushing. Such events should affect customers for a few hours at most. The discoloration is caused by iron (red color) or manganese (black color) particles being dislodged from the water main. If discoloration occurs, open the cold tap nearest the water meter to full flow until the water runs clear. In some situations, this may take 5 to 10 minutes. It is also advised that you make sure your water is clear before doing laundry or other projects for which discolored water could cause problems.
For further information, please contact our office at 925.372.3588.
We ask for your patience and understanding during this important main cleaning process.
