What is the minimum flushing requirement for dead-end mains according to current state regulations?

The minimum flushing requirement for dead-end mains is indeed established as once every month according to current state regulations. This is crucial for maintaining water quality in distribution systems. Dead-end mains can lead to stagnant water, which can harbor bacteria and contribute to the deterioration of the overall water quality due to sediment buildup and the presence of low-flow conditions.

Regular monthly flushing helps to ensure that any stagnant water is replaced with fresh water, which reduces the risk of microbial growth and maintains chlorine residual levels. This practice is essential in providing safe and potable drinking water to customers. By flushing these lines, utilities can also remove sediments and prevent taste and odor issues that might arise from accumulated materials in the pipes.

Utilizing this flushing frequency is part of a comprehensive approach to managing and ensuring a high standard of water quality, essential for public health and compliance with regulations.
