What is meant by "system flushing" in a distribution network?

System flushing in a distribution network refers to the process of clearing out stagnant water and sediment to improve water quality. This practice is essential for maintaining safe and potable water throughout the distribution system. Over time, sediments, biofilms, and stagnant water can accumulate in the pipes, potentially leading to taste, odor, or safety issues in the water supply. Flushing helps to ensure that fresh water replaces these stagnant areas, effectively removing contaminants and restoring optimal flow conditions.

The importance of this procedure cannot be overstated, as it directly contributes to the overall quality of the water being delivered to consumers. Flushing is typically performed by sending high-velocity flows of water through the pipes, which dislodges any buildup and carries it away, ultimately ensuring that the water remains safe and meets health standards.

Other options like the disconnection of service lines, regular maintenance of water meters, or the complete draining of the distribution system do not align with the goals of maintaining water quality or enhancing the efficiency of the distribution network in the way that flushing does.
