(A) Wells connected to existing irrigation systems shall be disconnected and plugged prior to connection to the effluent reuse system. An application may be submitted to the Utilities Director for the installation of a reduced pressure zone backflow prevention device on well connections rather than disconnection of the well.
(B) Existing irrigation systems shall be disconnected from potable water systems prior to connection to the effluent reuse system.
(C) A reduced pressure zone backflow prevention device shall be installed on the potable water supply to a property by a certified technician at the expense of the property owner or customer prior to connection to the effluent reuse system.
(D) A single-family residential customer may use reclaimed water, when available, by connecting his or her in-ground spray irrigation system directly to the effluent reuse system or, alternatively, by using the hose bib provided by the city, at customer's request, within a subterranean valve box at the property line.
(E) Industrial/commercial customers shall only use in-ground spray irrigation systems to apply reclaimed water.
(F) Control valve boxes and boxes for subterranean hose bibs shall be labeled "Reclaimed Water". The boxes shall be of the size and design required by the Utilities Department.
(G) All piping, pipelines, valves and outlets shall be color coded purple, or otherwise marked by permanent labeling, to differentiate reclaimed water from domestic or other water supplies.
(H) Maximum obtainable separation of reclaimed water lines and domestic water lines shall be practiced. A minimum horizontal separation of five feet (center to center) or three feet (outside to outside), shall be maintained between reclaimed water lines and either potable water mains or sewage collection lines. Reclaimed water mains crossing under potable water mains shall be laid to provide a minimum vertical distance of 18 inches between the invert of the upper pipe and the crown of the lower pipe. Where this minimum vertical separation cannot be maintained, the crossing shall be arranged so that the reclaimed water pipe joints and the potable water main joints are equidistant from the point of crossing with no less than 10 feet between any two joints.
