What is the recommended best time to perform a flushing program on the mains?

Performing a flushing program on the mains during late at night is considered the best practice for several reasons. This timing minimizes disruption to traffic and the surrounding area, which is particularly important in urban settings where daytime flushing activities could impede vehicle movement and create hazards. Additionally, flushing at night often leads to fewer customer complaints as most residents are typically at home, reducing the likelihood of inconveniencing them with changes in water pressure or temporary discoloration of water.

This approach allows maintenance crews to focus on the task without concerns about daytime interruptions and ensures that the flushing process is carried out more efficiently. Furthermore, water demand is generally lower at night, which can facilitate a more effective flushing process, aiding in the clearing of sediment and biofilm from the mains that contributes to water quality issues. Overall, conducting the flushing program late at night aligns with best practices to optimize both operational efficiency and customer satisfaction.
