(A) Standards and requirements. Water systems shall be of sufficient size to furnish adequate domestic water, to furnish fire protection to all lots, and shall conform with the city’s master plan, standard details, and city design standards and meet the requirements, in all respects, of TCEQ. The city shall make the final determination of the adequacy of water mains proposed. The water line sizes shall be designed according to the city standards (see Appendix), which are the water standards of the City of Plano with modifications by the City Engineer. Line sizes shall be as shown on the city’s master water plan, and the developer shall install all lines and system components at the developer’s cost.
(B) Location.
(1) All water mains shall be constructed within exclusive street rights-of-way or easements dedicated to the city and be parallel to the street right-of-way.
(2) Easements shall be provided for water mains which parallel any state numbered highway.
(3) Water mains shall be installed in or extended along all frontage streets of the proposed subdivision and shall be connected to all existing water mains as determined by the City Engineer. Provision of water mains in conjunction with cul-de-sac streets shall be at the discretion of the City Engineer. To ensure reliability of service, all extensions to the water system must provide for looping including cul-de-sacs unless a specific variance is given. Adequate capacity shall be determined by the standards for fire flow as accepted by the State Board of Insurance and the Fire Prevention and Engineering Bureau of the state.
(4) All water lines crossing under pavement and drainage structures must include steel encasement pipe. Water services lines must include PVC encasement pipe.
(C) Water line size. The minimum diameter of all water service mains shall be 8 inches. Valving shall be provided so that no more than 800 feet of line will be out of service unless approved by the City Engineer. Where dead-ends must exist, 8-inch diameter or larger mains shall be installed and fire hydrants or other means for flushing those lines shall be provided at the terminal ends. The minimum limits set forth in the above shall not be exceeded except upon the specific approval by the City Engineer, City Building Official, and the Fire Chief, but in no event shall these requirements be less than the minimum required by the State Board of Insurance and the Fire Prevention and Engineering Bureau of the state.
(D) Fire hydrants. Fire hydrants and valves shall be required for all subdivisions and additions and shall be located to satisfy the requirements of the city. Fire hydrants shall be located in accordance with the requirements of the City Engineer. To eliminate future street openings, all underground utilities for fire hydrants, together with the fire hydrants themselves and all other supply improvements, shall be installed before any final paving of a street shown on the subdivision plat. Reflective fire hydrant buttons shall be installed in all streets at a point adjacent to fire hydrants. The buttons shall conform to the City Engineer’s specifications. At corner locations, buttons shall be installed in both streets.
