§ 155.053  SEWER AND WATER SUPPLY.
   (A)   Sanitary sewage disposal.
      (1)   The developer shall install public sanitary sewer lines where public sanitary sewer service is available within 500 feet of the property in accordance with the policy of the Mount Pleasant  Waterworks and Chapter 51, Water and Sewers, of the Mount Pleasant Code of Ordinances.
      (2)   Sanitary waste disposal systems shall be designed according to criteria approved by the Mount Pleasant Waterworks.
      (3)   Septic tanks and fields shall be approved by South Carolina Department of Health and Environmental Control.
   (B)   Water supply.
      (1)   The developer shall install water lines when public water service is available within 500 feet of the property.
      (2)   Installation shall include fire hydrants, valves, house connections, and other appurtenances.
      (3)   All work shall be in accord with the policy of the Mount Pleasant Waterworks.
      (4)   Water supply systems shall be designed according to criteria approved by the Mount Pleasant Waterworks.
         (a)   All fire hydrants shall be of a type accepted by the Mount Pleasant Waterworks and the Mount Pleasant Fire Department:
            1.   Three-way with one 4½-inch discharge and two 2½-inch discharges;
            2.   With at least a 5½-inch foot valve; and
            3.   On a minimum 8-inch water main.
         (b)   Fire hydrant spacing shall not exceed 300 feet to structures.
      (5)   New residential subdivisions shall be designed to ensure that all fire hydrants have the capability to flow at a minimum of 1,000 gallons of water per minute, at 20 pounds per square inch residual pressure.
   (C)   Dry fire hydrants.
      (1)   As referenced herein, DRY FIRE HYDRANTS shall refer to a pre-engineered system of piping with a Fire Department-approved connection adjacent to a water supply, to which a fire truck can attach a hose to draft water into its pump, and which at the opposite end terminates in pipe with a submerged strainer.
      (2)   Dry hydrants are designed to provide an alternate or supplemental water source to public water systems, and for emergency fire-fighting purposes.
      (3)   Dry hydrants may be installed in and adjacent to ponds, lakes, and other approved non-tidal water sources.
         (a)   All dry fire hydrants shall meet requirements of the National Fire Protection Association Standard 1231, “Water Supplies for Suburban and Rural Fire Fighting.”
         (b)   Dry fire hydrants shall only be used as a temporary solution to achieve fire flows in urban and rural settings where there is no public water system available, and in urban settings with a public water system where the fire flow demand exceeds the capacity of the public water system.
         (c)   Dry fire hydrants shall be used as follows:
            1.   In urban areas served by a public water system, dry hydrants may be installed where their use does not exceed 33% of the building's required fire flow and in no case shall be greater than 1,000 foot roadway travel distance from the structure(s) to be protected.
            2.   In rural areas not serviced by a public water system, dry hydrants may be installed without travel distance requirements, based on individual case needs as approved by the Fire Chief or his or her representative.
            3.   Dry hydrants in rural and urban areas may remain the primary water source until such time as the area receives water service, or proper fire flow capacity, and then they shall be abandoned.
            4.   Dry hydrant(s) shall transfer with property ownership, with the new owner being responsible for maintenance and operation of hydrant(s) and water source per this section as if they were the original installer.
         (d)   Prior to installation, a dry fire hydrant application and permit form shall be filed with the Fire Chief, stating the reason for the request to install dry fire hydrant(s), along with providing NAPA Standard 1231 information regarding the hydrant's design and water supply.
         (e)   All applications for dry fire hydrants shall be accompanied by a letter of credit to ensure the dry fire hydrant(s) and water sources are maintained operational.
            1.   The letter of credit for each hydrant shall be in the amount of $1,000, and each shall include a fee of $135 per hydrant to cover the cost of inspection, annual testing and inspection of the water source by the Fire Department for each 36-month period.
            2.   All criteria hereunder shall be met prior to the town approving a permit.
            3.   Each permit shall be valid for 36 months, at which time a new dry fire hydrant application and permit form shall be filled out and submitted with the appropriate fee for permit renewal.
            4.   Renewals shall be limited to terms of three years.
            5.   Federal, state and local government entities are exempt from the fee and letter of credit requirements hereunder.
         (f)   The Fire Department shall test all dry hydrants and inspect water sources for visible problems on a semi-annual basis, with deficiencies being reported to the hydrant owner in the form of an order of correction.
         (g)   Failure to maintain the hydrant shall be a violation of this chapter and the Standard Fire Prevention Code.
         (h)   If a property owner or agent desires the dry hydrant to be tested annually by an outside source, they shall remit results to the Fire Department on forms provided.
            1.   However, the initial filing fee remains the same, and the Fire Department reserves the right to check the results and the water source, by inspection or testing if necessary.
            2.   The final determination pertaining to testing shall be made by the Fire Department.
