§ 153.156 REPAIR OF EXISTING DRAIN TILES AND STORM SEWERS.
   (A)   (1)   Drain tiles and storm sewers broken during the trench excavation shall be repaired so their carrying capacities shall not be impaired. Broken drain tiles shall be replaced with larger sized piping, either PVC plastic pipe SDR-26 or ductile-iron pipe, as shown on the detail in the drawings. The length of the pipe shall be such that it extends a minimum of ten feet on either side of the watermain.
      (2)   All repairs of drain tile encountered shall be observed by the developer’s engineer or a representative of the village prior to backfilling. Compacted granular backfill will be required as for any existing utility or structure.
      (3)   The pipe to field tile junction shall be wrapped with burlap and encased in concrete. Care shall be taken to prevent concrete from entering the flowline of the pipe.
   (B)   Drain tiles and storm sewers uncovered during the trench excavation which are laid parallel to the trench shall be protected and kept in service. Those tiles or storm sewers accidentally broken shall be repaired or replaced. If necessary, they shall be rerouted around the improvements.
(Ord. 97-7, passed 7-1-1997, § 5.16)
§ 153.157 CONFLICT MANHOLES.
   Drain tile or storm sewers discovered to be at the same elevation as a wastewater sewer under construction may be handled as follows.
   (A)   A manhole will be constructed at the intersection of the pipes.
   (B)   A 16-foot minimum section of ductile-iron pipe will be laid through the manhole (centered on the manhole) and will be connected to and become a part of the wastewater sewer. Connection of dissimilar pipes shall be made with suitable couplings and concrete encasement.
   (C)   The drain tile or storm sewer shall be connected to the manhole but not laid through it.
(Ord. 97-7, passed 7-1-1997, § 5.16)
§ 153.158 DITCH RECONSTRUCTION.

Water service lines shall be installed by the developer from the watermain to the property line and shall terminate at a curb stop. The individual homeowner is responsible for the installation of the water service from the curb stop to the home. The village is responsible for furnishing and installing only the individual water meters.
   (P)   Minimum cover for watermains and services shall be four feet and six inches.
   (Q)   All watermains shall be designed for a normal working pressure during average flow and use conditions of not less than 50 psi, and a minimum pressure of 20 psi under maximum flow conditions.
   (R)   Tie rod joint restraints shall be provided for all bends in the vertical plane.
   (S)   When the subdivider can show by cost estimates that is not economical to connect to the public water system (taking into account the cost of installing individual wells and their maintenance costs), the subdivider shall indicate that the lots are of adequate size to permit the construction of a well on each lot, at least 25 feet from any building, at least ten feet from any lot line, and at least 75 feet from any septic system seepage field. The well shall be situated clear of any driveway, parking area, or other source of contamination. There shall not be any future cross connections between the well system and any public distribution system. The subdivider shall show the location of other wells in the area on an area general plan and shall provide a written recommendation from a licensed well driller stating that an adequate well is likely to be established. The minimum lot size for lots with both a well and septic tank system shall be 25,000 square feet.

   (B)   All types of pipe shall be handled in such manner as will prevent damage to the pipe or coating. The pipe and fitting shall be inspected by the subdivider for defects while suspended above grade. Accidental damage to pipe or coating shall be repaired to the satisfaction of the developer’s engineer or be removed from the job. Methods of handling shall be corrected to prevent further damage when called to the attention of the subdivider.
   (C)   Dirt or other foreign material shall be prevented from entering the pipe or pipe joint during handling or laying operations and any pipe or fitting that has been installed with dirt or foreign material in it shall be removed, cleaned, and relaid. At times when pipe laying is not in progress, the open ends of the pipe shall be closed by a water-tight plug or by other means authorized by the developer’s engineer to ensure absolute cleanliness inside the pipe. Threaded pipe ends shall be protected by couplings or other means until laid.
   (D)   The watermains shall be laid and maintained to lines and grades established by the drawings and specifications, with fittings, valves, tapped, or bossed outlets, and hydrants at the required locations. Valve-operating stems shall be oriented in a manner to allow proper operation. Hydrants shall be installed plumb.
   (E)   All watermains shall be laid to a minimum cover depth of four feet, six inches. Depth shall be varied as necessary to accommodate crossings with other utilities. Record depth measurements shall be taken at intervals not greater than 100 feet to verify installed depth. Depth shall be determined to proposed finished grade.
   (F)   Record horizontal or vertical locations of all watermains shall be provided at intervals not greater than 250 feet to verify installed location. Long radius curves, either horizontal or vertical, may be laid with standard pipe by deflections at the joints for most rigid pipes and in the pipe for most flexible pipes. If shorter lengths are required, the drawings will indicate maximum lengths that can be used.
   (G)   Where field conditions require deflection of curves not anticipated by the drawings, the developer’s engineer will determine the methods to be used. Maximum deflections at pipe joints and laying radius for the various pipe lengths shall be as recommended by the pipe manufacturer or stated in applicable AWWA Standards. When rubber gasketing pipe is laid on a curve, the pipe shall be jointed in a straight alignment and then deflected to the curved alignment. Trenches shall be made wider on curves for this purpose.
   (H)   The trench bottom shall be true and even to provide support for the full length of the pipe barrel. The pipe shall be bedded in a minimum of four inches of pipe bedding. Holes for the bells shall be provided at each joint, but shall be no larger than necessary to allow joint assembly and to ensure that the pipe barrel will lie flat on the trench bottom. Pipe shall be installed in accordance with AWWA Standard C600.
   (I)   Maximum joint deflection angle for any watermain shall be three degrees.
   (J)   All watermains shall be constructed in accordance with the water and sewer separation requirements stated in §§ 153.140 through 153.159 .

The valve box shall be centered over the operating nut of the valve, with the box cover flush with the finished surface. Valve boxes shall be set true vertically and supported to remain so until all backfill has been placed.
   (L)   (1)   All hydrants shall stand plumb and shall have their hose nozzles parallel with the length of the street, with pumper nozzle (four and one-half inches) facing the street. Hydrants shall be set with the bottom flange of the top section two inches above ultimate final grade of the ground, with a maximum deviation of two inches in elevation being allowed.
      (2)   Each hydrant shall be connected to the main with a six-inch or larger diameter branch controlled by an independent valve. The valve shall be restrained to allow shut-off when the hydrant is to be removed. All hydrants and hydrant leads shall have restrained joints from the main to the hydrant including the connection to the main and the hydrant foot.
   (M)   Drainage shall be provided at the base of the hydrant by placing coarse gravel from the bottom of the trench to at least six inches above the waste opening in the hydrant and to a distance of one foot around the elbow. The surface of the coarse gravel shall be covered with geotextile filter fabric to prevent soil intrusion into the stone. Adequate support must be provided to prevent the fire hydrant from settling. The bowl of each hydrant shall be well braced against a sufficient area of unexcavated earth at the end of the trench with concrete thrust blocks.
   (N)   New watermains and appurtenances shall be connected to the existing piping in accordance with the details shown on the drawings. If the existing piping can be isolated from the system, the connections shall be made by using cutting-in-sleeves in the existing piping. If the existing watermains cannot be isolated from the system, the connections shall be made under pressure using tapping sleeves and tapping valves.
   (O)   Where the connection of a new watermain or appurtenance requires interruption of service and notification of customers affected, the village’s maintenance superintendent and subdivider shall mutually agree upon a date and time for the connections to be made. The date and time will allow ample time for the subdivider to assemble the labor and materials and for the village to notify all customers affected.
