CROSS-CONNECTION CONTROL

Plumbing cross-connections, which are defined as actual or potential connections between a potable and non-potable water supply, constitute a serious public health hazard. There are numerous, well-documented cases where cross-connections have been responsible for contamination of drinking water, and have resulted in the spread of disease. The problem is a dynamic one, because piping systems are continually being installed, altered, or extended.

WRE engineers perform water audits and cross-connection control surveys, where specially trained professionals inspect water systems to identify potential sources of contamination. WRE has provided these services to systems large and small, ranging from military installations serving a few hundred water users, to the City of San Francisco, serving over a million users.
