Backflow Prevention
The City of Delaware Water Distribution System Division takes very seriously backflow prevention and cross-connection control because the backflow of chemicals or contaminated water into the public water system is responsible for many illnesses and deaths every year in the United States. While cross-connections themselves are not bad and are often necessary, uncontrolled cross-connections are dangerous. A backflow prevention device is a mechanical device or piping configuration that prevents backflow of contaminated water into a potable water system from occurring at a cross-connection.
