A “prime meter” measures water consumed and disposed through the public water and sanitary sewer system respectively. “Irrigation meters” may additionally be installed to measure water which is not disposed through the public sanitary sewer treatment system. The water used for “irrigation meters” would include water for swimming pools, yards, gardens, or other uses where sanitary sewer service charges are not applicable. Irrigation meters shall be installed not more than four feet from the prime meter and shall be installed parallel to the prime meter. Sewer charges shall not apply to water amounts measured by irrigation meters. The water rate to be charged for irrigation meters shall be at the same rate as provided in Section 92.02 of this Code of Ordinances, and there shall not be any base rate charged. Shut off valves are required ahead and after the irrigation meter and must be within one foot of the meter. A back flow preventer (approved by the City) to protect against contamination of the water system must be installed after the irrigation meter. The irrigation meter must be installed with the arrow on the meter being in the direction of the flow of water to the outside. Underground irrigation systems are allowed in City right-of-way with the understanding that any repair of the irrigation system caused by maintenance of utilities will be at the homeowner’s expense.
