A boil water notice is a public statement advising people to boil their tap water before using it, typically in response to an event that has (or could have) introduced contaminants into the water distribution system. Such events include a large water main break, widespread loss of system pressure, or results of routine sample testing in the system. Although waterborne diseases are extremely rare, they can be serious. The risk is higher for infants, the elderly and persons with immune deficiency disorders. Suncadia Water issues boil-water notices even if the possibility of contamination is remote to safeguard the health of the community.
