(a) All water mains shall be of ductile iron or P.V.C. C-900 plastic pipe, and shall be installed to City specifications. The minimum thickness for ductile iron pipe shall be Class 52 for 4" through 10" diameter, and Class 54 for 12" diameter or larger. All ductile iron pipe shall have a bituminous coating complying with A.W.W.A. C-104 specifications and shall have an outside coating of bitumastic enamel, or approved equal. The chemical constituents of the ductile iron pipe shall meet the physical property recommendations of A.S.T.M. A-339 to insure that the pipe is suitable for satisfactory drilling and cutting. If P.V.C. C-900 plastic pipe is used, depending on location, such use may be precluded by the Ohio Environmental Protection Agency, the Utilities Director or other authorities of the City. Such P.V.C. pipe shall conform to ANSI/A.W.W.A. C-900-81, then shall be DR 25 Class (100 P.S.I.) or DR 18 (150 P.S.I.) or DR 14 (200 P.S.I.), depending upon applications. All P.V.C. pipe shall have buried underground detectable tape blue in color, and with metal wire enclosed for protection.
(b) All costs of plans, surveying, construction, authorized supervision and material furnished for connecting to or extension of main lines shall be the obligation of the developer of the subdivision or property owners requesting such extension.
(c) Three sets of plans shall be submitted, one to meet the approval of each of the following: the Ohio Inspection Bureau, the Ohio State Health Department and the Heath City Council.

The installer shall fill the remainder of the trench site with excavated material.
(g) Unless otherwise specified, the duration of any pressure test shall be one hour minimum. The test pressure should not exceed one hundred fifty percent (150%) of the normal operating pressure at the lowest elevation in the segment being tested, with the required minimum of 150 P.S.I.
(h) All water mains shall be laid 5' from ground level to the bottom of the main line installed.
(i) Subsequent construction and the completion of pressure testing, the water within the water main shall contain a minimum of fifty mg/l of chlorine residual for the forty-eight hour period. Then, after having been flushed clean, a sample shall be taken for bacterial testing and cleared before the line is put into service. (Ord. 79-89. Passed 10-2-89.)

All such services shall be at a minimum of three and one-half feet in depth.
(l) Lines shall extend to supply all properties in the addition and have hydrants with one four and one-half inch and two two and one-half inch standard fitting, and hydrants shall be placed every 500 feet with hydrant or blow off on any dead end to flush and clean the line. Hydrants shall be five and one-fourths inch in diameter and will be painted to City specifications, which is yellow barrel and blue caps.
(m) A hydrant shall be M and HT 129 or approved equivalent.
(n) Hydrant watch valve and box shall be installed between a main line and hydrant. All hydrant leads shall be a minimum of six inch line.
(o) Main line gate valves shall be installed at the location directed by the City. Valves shall be M & H or equal, and all materials used and construction procedures shall conform to A.W.W.A. specifications.
(p) Easement for laying and maintaining service must be provided for.
(q) All work shall be inspected by an agent of the Division of Utilities and his time shall be charged to the developer.
