Why is this change necessary?

This change is a common water system maintenance practice among water providers in states with warmer climates. North Texas Municipal Water District (NTMWD) uses it to maintain the system and ensure high water quality year-round. It’s important to do this before summer because hotter temperatures can increase the potential for bacterial growth in pipes.
