(A) Sewer improvements in subdivisions.
(2) (a) Extensions to District’s sewer system. All extensions to connect to the District’s sewer system shall be designed with maximum use of gravity flow pipeline facilities wherever feasible. In any case where sewer service is required and a choice exists for pumped service verses gravity service, then gravity service shall be constructed unless proven otherwise infeasible by the developer/owner or the developer/owner’s engineer to the satisfaction of the District.
(b) All pump stations installed to serve one individual, single-family unit shall be constructed, operated and maintained by the District.
(3) Dry sewer installation. All proposed development and/or projects proposed in areas where District sewer is not currently available but is scheduled to be installed within three years of completion of the development and/or project may install “dry” sewer infrastructure. The sewer infrastructure, including, but not limited to, mains, service taps, clean-outs, pumping stations, manholes, etc., shall be constructed in accordance with the DWQ construction standard specifications and shall be approved by the District and the state prior to construction.
(4) Re-use requirement. All new golf course developments requiring the use of water to maintain their property or existing golf course developments constructing a wastewater collection system to be connected to the District’s wastewater collection/transmission system shall be required to install a reuse system (also referred to as “purple pipe” or “gray water lines”) for disposal of treated wastewater effluent on the golf course(s) meeting or exceeding state and federal requirements for such use. The requirement shall be subject to the following criteria:
(a) The availability of District re-use water distribution/transmission lines in the area of the development and/or project.
(b) Availability of sufficient open space for disposal of treated effluent on the golf course or other allowable uses within the development.
(c) The use of groundwater shall be prohibited for golf courses if the District’s re-use system is available.
(5) Calculation of sewer usage. The District shall use and require others to use the “Wastewater Flow Rate” table found in 15A NCAC 2H .0200 — Waste Not Discharged to Surface Waters, or an equivalent document approved for use by the State of North Carolina, for calculating and estimating the sewer requirement for all applicable facilities and/or developments.
(B) Non-district sewers; interim arrangements. If the private sewer system operator uses a package treatment plant to provide interim treatment, the plant will be operated and maintained by the District. The developer/owner shall provide a five year performance bond or such security as the board requires set from time to time to ensure proper operation and maintenance. The District shall have the right to use the bond funds to operate, repair and/or maintain the system if the District determines that the plant requires additional repair and maintenance as a result of poor plant performance or incorrect plant design.
(C) Use of septic systems; interim arrangements. If District sewer is not available to the development or project, but is scheduled to be available according to the District’s master plan, the developer may choose to use septic tanks or some approved variation thereof. These systems shall be approved and constructed in accordance with the District’s Health Department and all other applicable regulatory agencies. The owner/developer may connect all septic tank systems to the public sewer system, at his or her expense, once the District makes public sewer available.
