We usually flush our larger systems, and those with commercial establishments, at night to minimize impacts to our customers. Smaller, strictly residential systems are often flushed during the day when a majority of residents are at work.
Water system flushing is the process by which we "clean" the insides of the water distribution system. High velocity water is flushed through the system to remove minerals that have built up inside the pipes. Periodic flushing helps maintain water quality and keeps the system operating as engineered.
