MINNEAPOLIMEDIA NEWS | Coon Rapids Local Government: Coon Rapids Begins Spring Fire Hydrant Flushing April 13; Residents Advised of Temporary Water Discoloration

COON RAPIDS, MN

The City of Coon Rapids began its annual spring fire hydrant flushing program yesterday, Monday, April 13, 2026, as part of routine maintenance to protect water quality and ensure the reliability of the municipal water system.

The work is expected to continue for approximately three to four weeks, with the schedule dependent on weather conditions. Crews are focusing on the southern and western portions of the city, primarily areas located south of Highway 10. Northern and eastern sections were completed during the previous annual cycle.

City officials have published a detailed map outlining flushing locations and progress, available through the City of Coon Rapids website.

Maintenance Purpose and Scope

Hydrant flushing is a standard practice used by municipal water systems to maintain infrastructure and water quality. The process involves opening hydrants to allow water to flow at high velocity through water mains.

According to city information, the procedure serves three primary functions:

• Sediment removal: High-velocity flow clears mineral deposits, including iron and manganese, and other sediment that accumulate inside pipes over time
• Water quality maintenance: Flushing removes stagnant water from low-flow or dead-end sections of the system, helping ensure fresh water circulation
• System testing: Crews verify hydrant operation and water pressure to support fire protection readiness

Temporary Water Discoloration

During flushing, residents may experience temporary water discoloration, commonly described as “brown water.” The condition occurs when sediment is disturbed within the pipes.

City officials indicate that while the water may appear discolored, it remains safe for drinking and bathing and continues to meet established health standards.

Guidance for Residents

The city has issued the following recommendations for residents during the flushing period:

• Check water before use: Avoid washing laundry if water appears discolored, as sediment can stain fabrics
• If staining occurs: Do not dry affected clothing; rewash using a rust-removal product after water clears
• Flush household pipes: Run cold water, preferably from a faucet without an aerator or from a laundry tub, until it runs clear
• Limit hot water use: Avoid using hot water or running appliances such as dishwashers during active flushing in the immediate area to prevent sediment from entering water heaters or filters

Additional guidance suggests that residents may flush internal plumbing after crews complete work nearby by running cold water from the lowest level of the home first, then progressing to upper levels.

Water clarity typically returns within hours to a few days following flushing activity in a given area.

Public Works and Infrastructure Maintenance

The annual hydrant flushing program is part of the city’s ongoing infrastructure maintenance strategy. In addition to improving water quality, the process ensures that fire hydrants remain fully operational and that the system can deliver adequate pressure during emergencies.

Residents experiencing prolonged discoloration or water quality concerns are advised to contact the City of Coon Rapids Public Works Department.
