Borough to flush fire hydrants, drain reservoir
In preparation for making repairs to its reservoir, the Borough of Duncannon will begin flushing fire hydrants in the Borough on Wedneday, April 19. Hydrant flushing will take place between the hours of 7 a.m. and 3:30 p.m. and is expected until Friday.
During the flushing, hydrants will be equipped with dechlorination diffusers which will help to prevent chlorinated water flowing into local streams and rivers.
While hydrants are being flushed, residents may experience low water pressure. Typically residents will also noticed a temporary discoloration of their water after flushing due to the unsettling of rust in the water mains. This discolored water is not harmful, but it can cause staining of laundry, especially white, or light-colored items.
Residents are advised to take the following steps if they experience discolored water.
- Open cold water faucets and let the water flow until it is clear. This may take a few minutes.
- Open hot water faucets and repeat the process.
- Wash a load or two of dark-colored clothes first
It is also advisable to fill some containers with tap water for use while hydrant flushing is ongoing.
Hydrant flushing is done annually to improve water quality by flushing sediment from the system. It also allows the Borough to identify malfunctioning hydrants and valves.
In this instance, the flushing will also help drain the Borough’s reservoir to allow crews to install new liner to prevent chlorinated water from leaking into the Sherman’s Creek watershed. Those repairs will begin on April 25 and are expected to take about a week to complete.
Residents are asked to make voluntary water conservation efforts while the reservoir is drained.
