What is Cross Connection?

Cross-connections, which are defined as actual or potential connections between a potable water supply and a non-potable source, where it is possible for a contaminant to enter the drinking water supply. External contaminant introduction diminishes the water quality of drinking water distribution systems. While there are cross-connection control programs in place in many locales, many others lack such programs. There is evidence that inconsistent implementation of such control programs can result in public health risk (NRC, Drinking Water Distribution Systems: Assessing and Reducing Risks, 2006). The problem is a dynamic one, because piping systems are continually being installed, altered, or extended. Control of cross-connections can be achieved through thorough knowledge, vigilance and education.

The Allenton Sanitary District does their own cross connection inspections for residential accounts.  For our Commercial , Industrial and Multi-Family accounts we contract with Hydrocorp for inspections and compliance.
