Everybody knows that hydrants are essential to provide water for fire protection, but they also serve a critical role in ensuring customers receive reliable, quality water service at their home or business.
Hydrants are necessary to flush the underground water system, improving water quality by removing mineral and sediment deposits that accumulate over time. While not harmful to customers, the substances can cause aesthetic water quality issues when they are not periodically flushed from the system.
The process is known as hydrant flushing, and it is an essential maintenance procedure all water providers must perform periodically to ensure the delivery of water that meets state and federal drinking water standards.
During flushing activities, hydrants are opened for a limited period at strategic points of the system, moving water through the pipes at a high speed to discharge the minerals and sediments that settle in the pipes over time. Flushing also helps to maintain flow and pressure in the water system.
Even in drought conditions, flushing is a necessary part of maintaining the water distribution system and the quality of the water within it. Golden State Water Company (Golden State Water) has modified procedures, given the current drought in California, to minimize the amount of water released during flushing activities. Water used for flushing represents less than 1 percent of the total water usage in each of our water systems.
Water discharged during Golden State Water’s flushing activities is done so in full compliance with state and federal regulations.
Customers may experience fluctuations in water pressure or the temporary presence of sediment in their water during flushing periods, but the condition is temporary and poses no health hazard. Water service should not be interrupted by flushing activities.
