Spring hydrant flushing begins in the city of Coon Rapids Monday, April 2.
The area planned for flushing this year is bordered by Highway 10 to the north and the Burlington-Northern Santa Fe (BNSF) Railroad double-line tracks to the south, starting at the city’s west border with Anoka and ending at TH 610.
According to information sent to residents by the city public works departments, the hydrant flushing involves an operator opening each hydrant to its maximum flow.
The flow stirs up iron deposits and settlements, removing them from the system.
Then the operator cleans and lubricates operating parts, checks the operation of the hydrant and valve, and records any needed repair work.
Residents in the immediate hydrant flushing area are cautioned that the flushing process may see temporary water discoloration, but this does not impact the safety of the water.
“If you experience discoloration after crews have been flushing in your neighborhood, clear the pipes in your own home by running all water faucets for a minute or two,” the public works department states.
“It’s best to avoid doing laundry until the discoloration clears.”
The city maintains over 290 miles of water lines, with about a third of the hydrants being flushed each year.
“The process of periodically flushing fire hydrants is an important maintenance activity,” the public works department states.
“Although it may appear to waste water, the process is part of a routine maintenance program necessary to maintain the water system and to continue to deliver the highest quality water possible to our residents.”
According to the public works department, flushing the water system on a routine basis removes sediment from lines and keeps the entire distribution system refreshed.
