Hydrants are flushed to make sure the hydrant and control valve are operational and do not leak. As citizens of Hinton, we are concerned that our fire protection systems are working. Hydrants are also flushed to clean out sediment in the main distribution lines. This allows the Town to maintain the high quality of water we deliver to our customers.
How do we flush hydrants?
Every hydrant in the Town of Hinton is flushed once a year. The hydrant is opened, and water is allowed to flow through the nozzle. This flushes water from the hydrant, cleaning the hydrant lead and the distribution main. ln 1995 a new method of hydrant flushing was introduced in the Town of Hinton. lt is a "unidirectional" method that involves closing off a section of the distribution system and allowing water to flow through the watermain in one direction. This method reduces the amount of water required to flush the hydrant and improves the quality of the flushing process.
When do we flush?
Hydrant flushing usually starts in early summer (weather permitting) and extends until September. ln this way every hydrant in the system can be flushed and cleaned. Hydrants are also flushed when a water quality concern is identified or anytime the water system has been depressurized for a repair.
Why do we allow water to be flushed out and not utilized elsewhere?
Ways to utilize the water being flushed onto the street have been investigated but are not feasible. The velocity of the water flow is critical to ensure proper flushing so attaching hoses or other devices to the hydrant is not possible since it reduces water flow.
What are the safety issues when flushing hydrants?
Vehicle safety is a major concern because vehicles must respect the warning signs to SLOW DOWN or their vehicle may suffer some damage.
Children playing around hydrants while they are being flushed are also a concern. Although our workers try to keep children off the street during flushing, drivers need to use extreme caution.
