Distribution lines are flushed periodically to:

increase water pressure in the system
reduce the risk of water hammer
ensure that chlorine does not accumulate in pipes
remove deposits from the pipeline

The correct answer is: remove deposits from the pipeline

Flushing distribution lines is primarily done to remove deposits from the pipeline. Over time, various materials such as sediment, biofilm, and other particulates can accumulate within the pipes. These deposits can lead to reduced water quality, decreased flow rates, and potential contamination of the drinking water supply. By flushing the lines, operators can dislodge and remove these accumulations, thereby maintaining the integrity and efficiency of the water distribution system. This process helps ensure that the water is clean, fresh, and safe for consumption. Flushing also helps to prevent issues such as clogging and corrosion that can arise from long-standing deposits. While there are other benefits to flushing, such as maintaining appropriate chlorine levels and mitigating pressure issues, the primary goal remains the removal of buildup in the pipelines to uphold system health.
