TUD Begins Its Annual Flushing Program

FLUSHING HYDRANT PIC

FRIDAY, JANUARY 20, 2023

SONORA, CA:  Tuolumne Utilities District (TUD or District) has begun its annual water line flushing program. TUD field crew members will be flushing water lines in various locations throughout the County between the hours of 7 a.m. to 3 p.m.  Flushing is expected to continue through April 2023.

Hydrant flushing is a routine preventative maintenance procedure that releases water from a fire hydrant at a high velocity allowing it to move through sections of the drinking water distribution system.  Do not be alarmed if you notice water running down the street or sidewalk in your neighborhood during flushing operations. During this process, you will be able to see crews flushing the water mains through fire hydrants and ends of water main pipes commonly called blow-offs. Crews aim to direct the water being flushed into appropriate areas to avoid sediment erosion or localized pooling of water, but you may notice water on the street or roadway.

What is water main flushing?
Water main flushing moves water systematically through sections of a drinking water distribution system, creating a scouring action to clean the line. The increased flow rate scrubs the water pipe’s inner walls and helps to remove build-up of naturally occurring debris and sediment.

Why is a flushing program important?

Loose sediment and other deposits may slowly build up on the inside of the water mains over time causing discolored water. Flushing at the appropriate velocities can remove these sediments and deposits and will improve taste, odor and color that may be problematic e.g., naturally occurring iron or manganese deposits in the distribution system may affect color.
