(a) A water supply system shall be designed and constructed in accordance with the requirements of the village and the State Environmental Protection Agency. Service lines will be required of the developer only where later installation would require removal of the pavement.
(b) The following minimum standards and specifications shall apply for the design of a water system.
(1) Pipes.
A. Main size shall be six inches minimum with the exact sizing based on pressure-volume calculations provided by the subdivider as approved by the Village. Generally, Insurance Services Office (ISO) recommended fire flow criteria shall dictate the minimum line size. (Ord. 93-31. Passed 11-15-93.)
B. Pipe materials shall be as follows:
1. Ductile iron pipe shall be cement lined design in accordance with ANSI/AWWA C150 and manufactured in accordance with ANSI/AWWA A21.51/C151. Minimum pipe class shall be Class 52. Pipe shall be push-on joint type.
(Ord. 93-31. Passed 11-15-93.)
2. Polyvinyl Chloride (PVC) pipe shall be in accordance with ANSI/AWWA C-900 latest revision. Minimum dimension ratio shall be DR 18. Joints shall be push-on type with elastomeric gasket.
(2) Fittings and joints. Fittings shall conform to ANSI/AWWA A21.53/C153 latest revision. Joints shall conform with ANSI/AWWA A21.11/C111 latest revision for mechanical joints. Thrust blocking or mechanically restrained joints shall be required per good engineering practice.
(3) Trenches and installation. Trenches for waterlines shall be excavated and backfilled in conformance with ODOT 603 for Type B conduits. Ductile iron pipe shall be bedded on fine aggregate six inches in depth and the bedding shall extend up around the pipe not less than thirty percent (30%) of the pipe outside diameter. The bedding shall be shaped to fit the outside diameter of the pipe for at least ten percent (10%) of the outside diameter and recesses shall be formed to fit the bell ends. PVC pipe shall be totally encased in a minimum thickness of six inches of fine aggregate. Tracing tape shall be placed directly on top of the bedding over the full length of all PVC lines.
The granular bedding shall be compacted per ODOT Item 603.04 for Type B conduits. Trenches under or within five feet of pavements or sidewalks shall be backfilled with ODOT 310 granular material compacted in place. One year of natural settlement may be accepted in lieu of granular material if soil conditions appear suitable (subject to approval by the Village). There shall be a minimum cover of four feet over water lines at all locations plus eighteen inches vertical and ten feet horizontal separation from any sanitary sewer line.
(4) Valves. Gate valves shall be Mueller Resilient Seat meeting ANSI/AWWA C509 or approved equal. Valves twelve inches and larger shall be the butterfly type. Valves shall open counter-clockwise and have a two-inch square operating nut. Valve boxes shall be three-piece, 5-1/4 inch screw adjusting type cast iron. Valve boxes installed in asphalt pavement shall be set in a minimum twelve inch wide concrete collar with a thickness equal to the pavement section and finished one quarter inch below the pavement surface. Seal concrete/asphalt interface with liquid asphalt cement. Valves shall be installed at street intersections as required for isolation. Automatic air release/vacuum breaker valves shall be provided as required by sound engineering practices.
(5) Fire hydrants. Fire hydrants shall be required at 300 foot intervals in business and industrial areas and 500 foot intervals in residential areas. Hydrants shall meet AWWA C502 (Mueller Type A-423 or approved equal) having a one inch square operating nut, a 5-1/4 inch valve opening counter-clockwise and two 2-1/2 inch and one 4-1/2 inch National Standard hose thread connections.
(6) Service lines.
A. Service lines shall be 3/4-inch Type K soft copper or 200 pounds per square inch rated polyethylene pipe Union, where required, shall be three part (Mueller H-15400 or approved equal). Polyethylene pipe shall meet AWWA C-901.
B. Service lines shall have a 3/4-inch corporation stop (Mueller H-15000 or approved equal) at the main and a 3/4-inch stop (Mueller H-15154 or approved equal) and cast iron curb box (Mueller H-10300 or approved equal) at the right of way.
(Ord. 93-31. Passed 11-15-93.)
C. Minimum final cover for water service lines shall be four feet.
D. Where service lines larger than 3/4-inch are required, components of equal quality to the above material shall be required.
E. Where service line taps are made on an existing mainline, the requirements of the Water Department bylaws shall be complied with.
F. The Village furnishes all labor and material other than granular backfill for three/fourths inch and one inch service lines within the public right of way.
(7) Dead end lines. Dead end lines are to be avoided. Where they cannot be practically eliminated, a suitable flushing hydrant shall be installed at the end of the line. A fire hydrant may be used for this purpose. Where a temporary dead end occurs which will be eliminated by the future extension of the line into adjacent, unplatted property currently owned by the subdivider, a flushing hydrant need not be provided unless service(s) are connected to the dead end section of the line.
(8) All waterlines shall be hydrostatically tested in accordance with ANSI/AWWA C600.
(9) All waterlines shall be disinfected in accordance with ANSI/AWWA C651 and shall pass bacteriological tests before being placed in service. Bacteriological testing will be performed by the Village Water Department using taps provided by the subdivider for this purpose.
