What is a distribution system flushing program?

A distribution system flushing program is a regular procedure aimed at cleaning the pipes within a water distribution system, thereby ensuring the quality of the water supplied to consumers. This process involves releasing a significant flow of water through the distribution pipes to remove sediments, biofilms, and any accumulated contaminants. Flushing helps in maintaining optimal water quality by the removal of stagnant water and any disinfection by-products that may have formed over time.

Regular flushing is crucial in areas where water demand is low or in parts of the distribution system that are less frequently used. By implementing this program, water utilities can help to ensure that the water remains safe and palatable for consumers, ultimately protecting public health. The other choices, while related to various aspects of water management, do not encapsulate the primary function of a flushing program, which is centered around maintaining and improving water quality through systematic cleaning of the distribution infrastructure.
