When is the best time to perform a flushing program on the water mains?

Performing a flushing program on the water mains is most effectively conducted late at night. At this time, water demand is generally lower due to reduced usage in households and businesses. This ensures that more water can flow through the mains, allowing for effective removal of sediments and stagnant water that may have accumulated. Flushing during low-demand hours also minimizes the impact on customers, as it reduces the chance of water discolored by sediment being delivered to consumers.

In addition to preventing inconveniences for users, flushing late at night provides an opportunity to maintain water quality by improving circulation within the distribution system and ensuring that any leftover disinfectants or chemicals are properly mixed and assessed for efficacy. Prioritizing water quality is crucial for public health and maintaining the integrity of the water supply infrastructure.

While other times may seem convenient for flushing, they may lead to increased disturbances or issues with water quality for consumers, making nighttime the optimal choice.
