How often should dead end water mains be flushed?

Dead end water mains should generally be flushed every 30 days to help maintain water quality and prevent issues like stagnation. Flushing these areas regularly ensures that any sediment, biofilm, or contaminants that may accumulate over time are removed, thus improving water clarity and taste. This practice is essential for maintaining the integrity of the distribution system, as dead ends can lead to parts of the water main where water does not circulate effectively, increasing the risk of microbial growth and other water quality problems.

Flushing every 30 days strikes a good balance between maintaining water quality without imposing excessive operational demands or costs associated with more frequent flushing. Therefore, adhering to this 30-day schedule is an effective strategy for managing the cleanliness and safety of the water supply in areas served by dead end mains.
