Managing Grey Water Systems

Recycled water is a safe and effective resource for nonpotable use. Properly managed recycled water has a very limited health risk, if any. To help in the proper management of recycled water, the State of California, the local city or county Health Department and the Recycled Water Agency have developed rules and regulations for the

safe use of recycled water. These rules and regulations are in place to insure that the User, its Site Supervisor and employees, and the public are protected from any health risk (real or perceived) that might be associated with the use of recycled water.

L Because recycled water is not suited for human consumption, every effort must be made to prevent the user’s recycled water system from being cross-connected with the potable (drinking) water system.

L Plans must be carefully reviewed to ensure against cross-connections and that proper equipment is to be installed

(Design Approval, page 10).

L The recycled water system must be operated under the authority of a “User’s Agreement” (page 8) that outlines any special considerations or requirements for the particular use site.

L The User must designate a “Site Supervisor” (page 14) who is responsible for managing the on-site water system. The Site Supervisor ensures the system is operated within

the established guidelines and is properly maintained (Maintenance, page 17).

L In cooperation with the User, the Recycled Water Agency and/or Producer will make regular inspections of the site (Periodic Site Inspections, page 17).

L The User must instruct all persons using recycled water of its proper use and precautions (Personnel Training, page 14).

L All piping and points of connection must be labeled with “Recycled Water -- Do Not Drink” (Marking and Equipment, page 21) and the universal “Do Not Drink” symbol (page 25).

L All recycled water use areas accessible to the public must be posted with signs visible to the public and must include

the statement “Recycled Water – Do Not Drink” (page 24) and the “Do Not Drink” symbol (page 25).

L An initial cross-connection test must be conducted to determine if there are any unknown connections between

existing irrigation and potable piping prior to construction of retrofit work (Initial Cross-Connection Test, page

26).

L Prior to connection with the recycled water distribution system, a final cross-connection test must be performed to verify that construction or retrofit work was performed correctly (Final Cross-Connection Test, page 26).

L In the event of a cross-connection incident, the User must implement an emergency response plan (page 27).
