(A) Watermain. Watermain size shall be a minimum eight inch diameter, unless otherwise stated in the city's comprehensive plan. Watermain shall be poly vinyl chloride (PVC-C900) pipe and shall meet all the requirements of the City Engineer's Association of Minnesota standard utility specification for watermain and service line installation and American Water Works Association standard.
(1) Mains shall be valved at intervals not to exceed 800 feet. Valve type shall be in accordance with city standard specifications.
(2) "Dead end" mains shall be looped if exceeding the allowed length of a cul-de-sac. The distribution system may require installing a larger main to benefit the entire water service in the city. The City Engineer shall determine location and size of mains larger than eight inches in residential areas. In commercial/industrial areas, watermain up to 12 inches may be required to meet normal distribution required in the development. The cost of normal distribution size and appurtenances shall be the responsibility of the developer. Size of pipe over and above the normal shall be installed and financed in accordance with city policy. All pipe sizes shall be consistent with the city's comprehensive plan.
(B) Water supply. Service connections shall be stubbed into the property line and new individual wells are not permitted as a primary water source for parcels created in the urban service area. In all subdivisions outside the urban service area, the subdivider shall either:
(1) Install a system providing each lot with an adequate supply of portable water; or
(2) State on his or her preliminary plat that purchasers of individual lots will be required to install their own approved wells. Private wells shall comply with all requirements of state law.
(C) Fire hydrants. Installation shall be pursuant to plans approved by the City Engineer and the Fire Department and shall be located in accordance with Insurance Service Office (ISO) and International Fire Code standards. Hydrants shall be placed at the end of all "dead ends," cul-de-sacs and at street intersections. Hydrant type and installation shall be in accordance with city standard specifications and shall not exceed 500 foot spacing in the urban service area.
(D) Sanitary sewer. Sanitary sewer shall be a minimum of eight inch pipe and shall be of a material approved for use in the city by the City Engineer. Main size will be determined by the sewage flow and grade in accordance with the city sanitary sewer plan.
(1) Size of pipe shall be determined by lateral service and/or trunk service. Lateral service shall be the responsibility of, and cost shall be borne by, the serviced property. The incremental cost to install trunk sewer in lieu of lateral sewer will be borne by the city for developments not deemed premature and provided sufficient funds are available in the trunk sewer fund.
(2) House services. All services shall be installed in accordance with the city's standard specifications.
(3) Electronic final design plans shall be submitted to the city in the format required by the City Engineer, typically AutoCAD, to allow the completion of record plans by the City Engineer.
(E) Sanitation. Water and sewer lines shall be installed and connected to the public system to serve all lots within the proposed subdivision under the provisions of applicable statutes and ordinances. The City Council shall require the installation of water and sewer mains, at the applicant's expense or under the provisions of applicable statutes and ordinances.
(F) Telephone, electric, cable, gas service lines and/or other public utilities are to be placed underground in accordance with the city's right-of-way ordinance.
