(a) Water lines shall be designed, sized and constructed so as to be in conformance with all of the following:
(1) The City Standard Plans and Specifications.
(2) The Ohio Environmental Protection Agency (OEPA.)
(3) The current rules and regulations of the Utility Department of the City of Chillicothe.
(b) Fire hydrants shall be located so that adequate fire flow to each structure, based on the current guidelines of the Insurance Services Office (ISO) can be met, but in no case shall be more than 350 feet from another fire hydrant, or as otherwise required by the Chillicothe Fire Department.
(c) Water lines should be located within the street right-of-way, except under special circumstances when this requirement may be waived by the Planning Commission. In such cases, the line shall be provided with permanent access easements.
(d) The standard minimum size of water mains shall be six inches (6"). If larger line sizes are required to accommodate future growth, or to provide for fire flows in excess of those required for the proposed development, the City may participate in costs for the size increase, in accordance with the procedures of Chapter 1191.
(e) Minimum cover for water lines shall be forty-eight inches (48"). Water mains shall be laid so that at least ten feet (10') of horizontal distance and eighteen inches (18") vertical distance is maintained between the water main and any sanitary or storm water sewer line. In cases where ten feet (10') of horizontal distance cannot be maintained, such as a crossing, the vertical distance shall be maintained and such sewer lines shall be constructed of water line material.
(f) At crossings of water mains and sanitary sewer lines, one full length of water pipe should be used in order that both joints will be as far away from the sewer line as possible. All crossings shall be made at a 90 degree angle.
(g) The water system shall be designed in order that the minimum residual pressure at the highest inhabited floor of any building shall be not less than 20 psi.
