Maintaining the water distribution system is critical to ensure customers receive the best water quality. An important maintenance task is to ensure water movement through the system. Dead-end mains, typically in cul-de-sacs, at the end of rural streets, or even in a looped line, are known problem areas for water stagnation, resulting in quality complaints. Residential neighborhoods under construction and large underpopulated developments often have slow-moving or stagnant drinking water.
