4 WATER SUPPLY A community water system is being developed. Four wells have been drilled. The first well was put into service on April 14, 1997. Three additional well sites are shown in Phase III. The status of the community well system is included as an attachment in this agenda packet. All of the wells are located within common open space area to be owned by the homeowners association. The number of well which will actually be needed to served the development will not exceed the number approved with the Preliminary Plans. However, depending on the yield of each new well, use of all of the designated well sites may not be necessary. Community wells are regulated by the Public Water Supply Section of the NC Division of Environmental Health (DEH), which administers the NC "Rules Governing Public Water Systems". These rules include regulations pertaining to both surface water and groundwater withdrawals, and apply to all public water systems (e.g. Town of Hillsborough and OWASA), and to all community water systems with 15 or more connections. 1. Procedural Requirements Community wells must be operated by a private operator certified by the North Carolina Water Treatment Facility Certification Board. Below are State and local procedural requirements. a) Prior to Preliminary Plan Approval • Well sites must be approved by DEH, and a utility plan for the proposed storage and distribution system must be prepared. Documentation from DEH indicating approval of the well sites is attached. The Utility Plan has been provided to the Board of Commissioners as an enclosure with this agenda packet. b) Prior to Final Plan Approval • The well must be drilled. Environmental Health inspects and approves the well construction. • After the wells are drilled, the water must be tested. DEH criteria relating to water quality and quantity must be met. Requirements pertaining to water quality include disinfection, bacteriological testing and chemical analysis. With respect to water quantity,the combined yield of the well to be included in the system during a 12-hour period must equal at least 400 gallons per connection. The two wells must produce at least 18,800 gallons in 12 hours for the proposed subdivision. • If the well passes water quality and quantity tests, DEH must approve the engineering plans for the water distribution and storage system. • As required in the attached Resolution of Approval, the water system must be constructed prior to Final Plat approval.
