Water system flushing begins March 12

You might see water flowing from the fire hydrants around Pocatello starting March 12.

On Monday, crews with the City of Pocatello Water Department will begin the annual effort of flushing the water distribution system that delivers your clean water.

During the process, workers open the valves on fire hydrants around the city allowing water to remove any build-up of material in water pipes.

“Flushing the system performs several functions,” said Justin Armstrong, Water Department Superintendent. “First, it helps to clear any sediment build-up within mainline pipes to ensure residents are receiving high quality water. Second, it allows us to verify the condition and proper operation of fire hydrants. Last, it also helps us identify any inefficiencies within the system.”

During the system flush, you may notice a temporary drop in water pressure. Also, water may be rust-colored or cloudy, but Armstrong says the discolored water is not harmful and will clear up in a few hours.

“If you see a crew flushing a hydrant on your street, avoid running tap water and using a washing machine or a dishwasher until the flushing is complete,” Armstrong said. “If you see crews in your neighborhood, please drive carefully and treat them like any other road construction crew.”

Officials estimate the flushing process will take about three weeks.
