(A) Minimum requirement. All existing lawn irrigation systems must have a reduced pressure principal assembly as a minimum containment device.
(B) Water supply. All proposed in-ground irrigation systems that will be supplied with water through connection to the water system must have an approved above-ground reduced pressure zone backflow preventer as a minimum container device.
(C) Meters. All proposed in-ground irrigation systems that will be supplied with water through connection to the water system will be measured through a separate meter serving the irrigation system.
(D) Methods of connection and payment.
(1) An irrigation system service line may be installed by a direct tap into the main (dedicated tap) or by a tee off the non-irrigation (domestic) service line at a point between the main and the non-irrigation meter. Either method of connection, and the water meter, must be installed by the County Public Utilities Department.
(2) Customers will be required to pay all fees in advance of the installation of the taps and meter. The customer will also be required to pay the current monthly minimum and rate for any water used for the irrigation system, in addition to domestic or other water fees. Failure to make payment when due will result in having both irrigation and domestic water supplies disconnected for non-payment.
(E) Technical and other requirements. All irrigation service lines, meters and all related appurtenances will be installed in accordance with the same regulations, policies, and procedures as govern the installation of non-irrigation water systems; provided, however, that all irrigation meters will have an approved above-ground reduced pressure zone backflow preventer installed on the line after the meter and before any yard hydrants, control valves, tees, and the like. This backflow device will be installed, maintained and tested annually, at the customer’s expense, in accordance with the State Department of Environment and Natural Resources Public Water Supply Guidelines for Cross-Connection Control in Water Distribution Systems.
