Commonwealth Declares a Level 3 – Critical Drought in Central and Northeast Massachusetts

    MASSACHUSETTS DROUGHT ALERT

Drought and Water Main Flushing
Flushing during a drought, while seemingly counterintuitive, is essential for maintaining water quality, system reliability, and safety:

Prevents Stagnation: Dead-end lines can lead to water stagnation, resulting in poor taste and odor. Flushing keeps the water fresh and improves overall quality.

Reduces Biofilm Growth: Biofilm—a thin layer of microorganisms—can form inside distribution pipes. Flushing helps to reduce biofilm, improving water quality and reducing potential health risks.

Removes Sediment Buildup: Sediments can accumulate over time in dead-end lines, causing discoloration and affecting water clarity. Flushing helps remove these deposits, maintaining cleaner water.

Maintains Disinfectant Levels: Chlorine levels can diminish in stagnant areas, reducing water safety. Flushing ensures that disinfectant residuals are adequate, keeping the water safe for consumption.

Ensures System Reliability: Flushing dead-end lines also helps monitor water pressure and flow, ensuring the system is operational for firefighting and other emergencies.
