Cross Connection Control

Water distribution systems are large networks of storage tanks, valves, pumps, and pipes that transport finished water to consumers. By their design, distribution systems and infrastructure can be contaminated. Contamination most commonly occurs at a cross-connection. This is any actual or potential connection between public water and a contaminated source.

Tips for Correcting Cross-Connections

Do not submerge hoses or place hoses where they could become submerged, such as sinks, tubs, or pools

Install hose bib vacuum breakers on hose spigots

Have your plumbing system surveyed for cross-connections by a certified backflow preventer inspector

Ensure the correct backflow preventer is installed on your irrigation system

Have your backflow prevention assembly(s) inspected annually by a certified backflow preventer inspector

Immediately replace or repair any backflow prevention assembly that fails inspection
Submit annual inspection reports to Del-Co Water
