How is water quality typically improved during maintenance?

During maintenance, flushing the system is a crucial practice for improving water quality. Flushing involves moving water through the pipelines at a higher velocity, which helps to dislodge and remove sediments, biofilm, and other potential contaminants that may have accumulated over time. This process not only cleans the pipes but also refreshes the water within the system, ensuring that residents receive cleaner, fresher water.

While expanding the pipeline size might increase capacity or flow, it does not inherently improve the quality of the water already present in the system. Adding chemicals can adjust water properties or address specific issues, but this approach may not be used uniformly during maintenance and does not necessarily clear out contaminants as effectively as flushing does. Decreasing water pressure might actually exacerbate issues, leading to stagnation and potential buildup of unwanted materials in the system, rather than promoting the circulation necessary for maintaining water quality. Thus, flushing the system stands out as the most effective way to enhance water quality during maintenance activities.
