The City of Plymouth begins its annual water main flushing in mid-April, which is preceded by a round of citywide street sweeping.

Street cleaning is completed three times per year to protect Plymouth's lakes, creeks and wetlands.

City crews began sweeping streets ahead of the water main flushing schedule to help prevent excess pollutants, such as salt, sand, leaves and debris, from being flushed down the storm sewer catch basins and into Plymouth’s water bodies.

The city will flush water mains based on the schedule below.

• April 17-19: Residential areas south of County Road 6, between Gleason Lake Drive and Interstate 494, and industrial areas on both sides of I-494, south of Highway 55
• April 19 to May 8: Residential areas west of I-494, except areas along both sides of Chankahda Trail (formerly County Road 47) west of I-494
• May 8-25: Residential areas east of I-494, and areas along both sides of Chankahda Trail west of I-494

Residents can find out when their specific area will be flushed at plymouthmn.gov/watermainflushing or by calling 763-509-5950. Water may be discolored throughout this time, but it is more likely while the nearby area is flushed.

Those who notice discolored water can avoid doing laundry until the system is clear. Residents can also run their outdoor water faucet until the water runs clear.

Maintaining clean streets is a high priority for the City of Plymouth because of its commitment to surface water quality. On average, more than 1,200 tons of material – the equivalent of 2.4 million pounds – is cleaned off of city streets each year. Street sweeping is typically completed in April, June and August in Plymouth.
