What is the primary reason for flushing a water distribution system?

Flushing a water distribution system primarily serves to remove sediment and improve water quality. Over time, pollutants, rust, and sediment can accumulate in the pipes, leading to potential health risks and compromised water quality. By flushing the system, these undesirable materials are expelled, helping to ensure that the water remains clean, safe, and free from contaminants. This process not only enhances the aesthetic qualities of the water—such as its taste and smell—but also plays a critical role in maintaining overall system health and compliance with safety standards.

While improving odor and taste may be a secondary benefit of flushing, the primary aim is to ensure better water quality by eliminating sediment build-up. Increasing pipe pressure and reducing water temperature are not the main purposes of flushing; rather, they are more connected to specific operational or environmental conditions that can be addressed through different Management practices.
