How do I prevent a cross-connection with my recycled water or rainwater irrigation system?

Recycled water and rainwater should not be placed in storage containers that are connected to piped landscape irrigation systems or to a drinking water supply. Recycled water and rainwater storage containers may only be connected by hose to separate irrigation systems (i.e., hoses connected to above ground drip irrigation systems or sprinklers that are disconnected from potable water supply). Additionally, all equipment (hoses, etc.) and storage containers that come into contact with recycled water or rainwater should be dedicated for use only with non-potable water.

For instances where different systems (potable, rainwater, or recycled water) could come into contact with each other, these must be inspected by the City and verified to have an air-gap separation to prevent cross-connection to the drinking water supply.
