Hydrant Flushing Starting June 1

May 29, 2026

MAWSA crews will be conducting routine hydrant flushing in the northern end of the service area beginning Monday June 1 and continuing over the next few days, generally between 8:00 a.m. and 3:00 p.m.

Hydrant flushing is an important part of maintaining a reliable water system. This routine maintenance helps remove naturally occurring minerals from water mains, supports overall water quality, and allows crews to verify proper hydrant operation for fire protection.

During flushing activities, customers in affected areas may experience temporary drops in water pressure or brief periods of discolored water. The discoloration is typically caused by harmless mineral sediment being stirred within the pipes and should clear after running cold water for several minutes.

Residents are encouraged to: • Run cold water until clear if discoloration occurs • Check faucet screens for sediment • Confirm water is clear before washing laundry or running dishwashers

Motorists are asked to use caution around MAWSA crews and allow extra space due to wet roadway conditions.

We appreciate the community’s patience and cooperation as we perform this important system maintenance.
