Hydrant Flushing Operations in the Old Town Water District


The hydrant-flushing program is very important to the maintenance of the Districts domestic water distribution system. Each year, Old Town Water District water technicians systematically open hydrants throughout the city to allow water to flow at a high velocity through the distribution main lines. This operation serves the following purposes:

Enhances water quality by removing sediments from inside the main line and flushing them out through the hydrant.

Identifies any malfunctions of the hydrants and related valves.

Helps determine weaknesses in the water distribution system.

identifies inadequate water volumes and pressures in the main lines.

Maintains Water Quality - The flushing will help to keep the mains cleaned and flushed out of sediment or other debris that could eventually have a negative effect on the quality of water (including taste and odor). This is especially important on side streets and dead-end lines that only see low and/or one-way flows.

Verifies Hydrant Operations - The regular operation of all hydrants in the system will confirm their proper operation and allow for identification of hydrants and valves needing maintenance.
