Members present were: District Commissioners William A. Caster; Robert G. Greer; William E. Sisson, Jr.; Vice-Chairman Sandra Barone; Chairman E. L. Mathews, Jr.; County Manager, Allen O'Neal; County Attorney, Wanda M. Copley; and Clerk to the Board, Lucie F. Harrell. Chairman Mathews called the meeting to order. APPROVAL OF MINUTES Motion: District Commissioner Sisson MOVED, SECONDED by District Commissioner Greer to approve the minutes of the Regular Meetings of August 2, 1993, and August 16, 1993, as presented by the Clerk to the District Board. Upon vote, the MOTION CARRIED UNANIMOUSLY. NON-AGENDA ITEMS Chairman Mathews inquired as to whether anyone from the general public would like to present an item not listed on the Regular Agenda. No items were presented. APPROVAL OF REQUEST FOR PARTICIPATION IN THE UPGRADE OF THE NORTHEAST INTERCEPTOR AND APPROVAL OF BUDGET AMENDMENT #94-0039 County Engineer, Wyatt Blanchard, reported the Northeast Interceptor is the main sewer trunk line which transports wastewater from the eastern and northeastern sections of the county to the wastewater treatment plant on the River Road. The Northeast Interceptor is a series of pump stations and force mains that was jointly constructed by the County and City in 1983; therefore, it is jointly owned. Two pump stations along the interceptor were designed for installation of one additional pump at each station to meet future flow needs. Due to present peak flows, the time has come to add the additional pumps, which will require new controls and generators. The cost is to be divided between the District, the City of Wilmington and Town of Wrightsville Beach as follows: New Hanover County $372,348 City of Wilmington $372,343 Town of Wrightsville Beach $106,000 NEW HANOVER COUNTY WATER AND DISTRICT BOARDBOOK 2 REGULAR MEETING, SEPTEMBER 8, 1993PAGE 122 (CONTINUED MEETING OF SEPTEMBER 7, 1993) The total cost of the project is $850,696, and it is important to note that this expansion will adequately handle peak flows for ten years. Also, the additional sewer capacity in the Ogden area has greatly exceeded the available capacity. For this reason, it is extremely important to proceed with the construction of the northside wastewater treatment plant and completion of the interceptor to serve the Ogden and Porters Neck area. Construction of the northside wastewater treatment plant will prevent an additional expansion of the Northeast Interceptor in the near future, which will cost several millions of dollars. The District Commissioners were requested to approve the participation in the expansion of the Northeast Interceptor as presented and approve the associated Budget Amendment. Motion: District Commissioner Sisson MOVED, SECONDED by District Commissioner Caster to participate in the expansion of the Northeast Interceptor in the amount of $372,348 and approve the following Budget Amendment. Upon vote, the MOTION CARRIED UNANIMOUSLY. #94-0039 Water & Sewer District Debit Credit Sewer Operating Fund/W & S -Engineering Appropriated Fund Balance $372,348 Water & Sewer - Engineering Capital Outlay - Other Improvements $372,348 Purpose: To appropriate sewer operating fund balance in the amount of $372,348 for upgrade of Northeast Interceptor. APPROVAL OF CONTRACT #94-0057 WITH MCKIM & CREED ENGINEERS, P.A. TO PERFORM A FEASIBILITY STUDY OF THE OGDEN AND PORTERS NECK AREA FOR HANDLING OF FUTURE FLOWS FROM THE AREA County Engineer, Wyatt Blanchard, reported staff has reviewed several new subdivisions to be constructed in the Ogden area and feels it is critical that steps are taken at this time to prevent overloading of the interceptor. McKim and Creed have been requested to perform a feasibility study for the Ogden and Porters Neck area to determine the logical way in which to handle future flows from this area. The feasibility study will cost $7,800 and includes the following services: SCOPE OF SERVICES: 1) Determine flow projections for the proposed service area utilizing the 201 Facility Plan update, design notes/criteria for the Westwood pump station and other available data. The flow projections would be modified as necessary to reflect NEW HANOVER COUNTY WATER AND DISTRICT BOARDBOOK 2 REGULAR MEETING, SEPTEMBER 8, 1993PAGE 123 (CONTINUED MEETING OF SEPTEMBER 7, 1993) known development plans. Determine the impact on the Northeast Interceptor system. 2) Develop preliminary wastewater effluent loadings on golf course sites including Landfall and Porters Neck. There is no proposal to include hydro-geologic evaluation at this time. 3) Evaluate the impact that current Groundwater Compliance Boundary Policies will have on the proposed effluent disposal systems. 4) Develop a conceptual design of the wastewater treatment plant to serve the area identified. 5) A cost estimate for the wastewater treatment plant would be developed based on typical costs for similar facilities. 6) Evaluate the long-term viability of a wastewater treatment plant with spray irrigation for the northeast portion of New Hanover County. This would include determining the impact that such a facility would have on the capacity and cost of a proposed wastewater treatment plant near the City's existing Northside Wastewater Treatment Plant. 7) Develop conceptual design of transmission facilities to convey wastewater from existing collector systems to the wastewater treatment plant and to the spray irrigation disposal site(s). 8) Provide cost estimates of proposed transmission facilities. 9) Identify required modifications to existing golf course irrigation facilities, including storage lagoons, piping systems and control systems that would be required to facilitate spraying of effluent. 10) Determine impact on proposed wastewater treatment plant for receiving and treating septage from septic systems within New Hanover County. 11) Prepare written report to present findings and recommendations. The District Commissioners were requested to approve the contract with McKim & Creed Engineers, P.A. to perform the feasibility study. Funds have been budgeted for the study.
