The semi-annual flushing of dead-end water mains throughout Glen Cove will start the first week of April, according to the city.
The process will last for about two weeks.
The flushing is done to remove accumulated dissolved mineral sediments from the water mains before the year's peak usage period of spring and summer.
Some water pressure fluctuation and discoloration should be expected, the city said. Though the discoloration poses no health risk, the city said residents may want to keep a supply of clear water in the refrigerator for drinking and cooking to use when it occurs.
The second flushing is done in October, after the peak usage period.
Any questions may be directed to the Water Department at 516-676-5096.
