Annual Hydrant Maintenance, Testing, and Flushing 

Flushing Year: 2022

Orange City Utilities Department has completed all work pertaining to the 2022 Annual Hydrant Maintenance Program. This annual fire hydrant testing and maintenance program complies with the Insurance Services Office (ISO) National Fire Protection standards.

Why are hydrants flushed?
Hydrant flushing is necessary to test the hydrants to make sure adequate flow and pressure is available for fire protection and to identify any malfunctions of the hydrant and related valves. Flushing is also done to remove sediment from pipes in order to maintain water clarity and quality in the distribution system.

When will you be in my area flushing?

Due to scheduling, it is difficult at this point to pinpoint the exact day and time that your street or neighborhood will be flushed. At time of flushing City staff will place signs throughout the flushing area to inform residents of flushing dates. Information can also be found on the City’s social media platforms.

What should I expect when crews are flushing in my area?

While hydrants are being flushed, customers may temporarily experience low water pressure or discolored water.

Why is the water pressure low?

Water pressure may be low due to the flushing of hydrants, which can lower the water pressure in the testing area.

Why is my water brownish/rust/tea-colored from the hydrant flushing? Is the water safe?
When a hydrant is opened, the water in the mainline will flow out at a high velocity. This creates a scouring action in the pipe and dislodges the sediment particles that may have accumulated in the pipe. The sediment then mixes with the water, turning the water a cloudy or rusty brown color.  There is no health hazard associated with the discolored water.

What should I do when City crews are flushing hydrants in my area?
Residents should avoid using their dishwasher and washing machine. Also, do not turn on the faucets within the household while City crews are flushing within your area. And, if you are driving in the work zone, please drive carefully.
