Annual Water Main Line Flushing Program
Each spring, the City of Longmont water staff flush the main water lines to keep water quality at its highest level and to ensure that fire hydrants are operational. The benefits realized in water quality and fire protection far outweigh the comparatively small amount of water released during the flushing program.
Residents may notice low water pressure, discolored water, or no water for short periods of time when flushing is taking place in their neighborhood. We recommend residents limit water use, and particularly avoid using hot water when flushing is occurring in their immediate area.
