WATER MAIN FLUSHING
An essential part of our system’s maintenance program is to flush hydrants every spring and fall in an effort to clear our water mains of sediment and mineral build-up. This practice improves water quality and helps to extend the life of our water mains.
Water main flushing moves water systematically through sections of our drinking water distribution system, creating a scouring action to clean the line. The increased flow rate scours the water pipe’s inner walls and helps to remove build-up of naturally occurring debris and sediment.
The water is discharged through select hydrants onto local roads or other surface areas. This process is critical to the overall maintenance of a distribution system and is one of the most important practices carried out by public drinking water systems to maintain high water quality, improve the carrying capacity of pipes, and ensure proper operation of distribution system components, such as hydrants and valves.
