The following minimum size and spacing criteria shall govern the design of extensions to the water supply system:
A. Main Size: Water main size shall be based on City of Sidney master plan and hydraulic model for current and future demands. If larger public water mains are required to serve a new development or future development, then the applicants requesting the water extension involved shall install such larger water mains at their expense.
B. Water Main Valves: Valves shall be located on public water mains so that the maximum shutoff lengths do not exceed five hundred feet (500') in all commercial areas and eight hundred feet (800') in residential areas. All such valves so required shall be of the same diameter as the public water mains they are appended to.
C. Fire Hydrants And Branches: Shall be placed to meet or exceed City of Sidney, MDEQ and Montana Public Works requirements. Fire hydrant branches shall have a minimum diameter of six inches (6"). In all cases a valve shall be installed on each fire hydrant branch and in no case shall the valve be of smaller diameter than the fire hydrant branch. Branch valves shall be located not more than eighteen inches (18") from the branch feeder main. (Ord. 354, 2-21-1984; amd. Ord. 588, 1-19-2021)
