Backflow Prevention

What are Cross Connection Control Points?

Cross connection control points are locations where the potable water system could come into contact with non-potable water or substances. These include hose bibs, irrigation systems, fire sprinkler lines, or any plumbing configuration connected to an alternative water source. SLWSD uses backflow prevention devices—such as double check valves and reduced pressure zone assemblies—at these points to ensure water flows in only one direction, protecting the integrity of the public water supply.

What Residents Can Do (Backflow Prevention):

Residents should avoid submerging hoses in pools, buckets, or chemical containers and never connect reclaimed or well water to their household plumbing. By following these simple practices and maintaining their backflow devices, SLWSD residents help safeguard the community’s drinking water quality and ensure compliance with state and local regulations.
