The municipal drinking-water distribution system is a complex delivery network designed to provide adequate potable water needs to entire communities. Much information has been published relative to concerns of the distribution system integrity and ability to provide safe, consistent water to consumers. Needs for infrastructure improvements, rapid response to main breaks and leaks, biofilm control and preventing intrusion events, dead legs and pressure losses, are just some of the prevalent water quality delivery issues. Less common are discussions around safe water storage prior to delivery. Although industry standards and guidelines exist, maintaining water quality over prolonged storage presents additional challenges and uncertainties for end users.
