What kind of signage is required to protect the public from recycled water?
One of the requirements for sites using recycled water is the placement of signs around the reuse area to advise the public that recycled water is being used. Statewide, these signs commonly portray a positive message that the business is participating in potable water conservation by using recycled water. The signs for use within the City of San Diego read “We are conserving our most valuable resource by irrigating our landscaping with recycled water,” as well as the message “Caution – Do Not Drink.” In addition, pipes, sprinkler heads, meter boxes and other irrigation equipment must be properly marked or color coded purple to avoid any potential for cross-connections and to distinguish the equipment from potable supplies equipment.
