007 <br /> After strategic review of the existing and proposed sewer systems in Efland, an alternative <br /> engineering design may create short and long term benefits in costs and service area. Abrief <br /> explanation follows; <br /> The present Efland sewer system flows by gravity to the existing McGowan Creek Lift Station <br /> (MCLS) built in 1988 near Efland-Cedar Grove Road. From this collection point sewage is then <br /> a pumped via a sewage force main to the Town of Hillsborough for treatment. The Central <br /> Efiand Phase II (area east of and downstream from the MCLS) proposes a new sewage lift <br /> station on Brookhollow Road (BRLS) which collects a-new service area that flows by gravity to <br /> this new station that is then pumped 'upstream'to the old MCLS. <br /> Since the proposed BRLS 'is 'downstream' from-the old MCLS, a-new gravity sewer main or <br /> interceptor can be designed to allow existing sewer flows to-flow through (without pumping) the <br /> MCLS and continue through this new gravity line (approximately 2,000 LF) to the BRLS. This <br /> alternate design accomplishes several_goals:- <br /> 1. Eliminates the need for a new lift station (BRLS) to pump to an old lift station (MCLS) <br /> which is to need of approximately$400,000 of repair. <br /> 2. Creates a new interceptor service area (consistent with the Efland-Mebane Small Area <br /> Plan) for additional property and customers that were not included in the original design. <br /> 3. Reduces the distance of .pumping to Hillsborough since the BRLS is closer and <br /> • eventually can be the one lift station instead-of two (major reduction in maintenance and <br /> operating costs)that changes pumping direction to another treatment system. <br /> 4. Removes the old MCLS function which is close to McGowan Creek. <br /> There are two funding sources for-this project- $3.5 million from the State Revolving Loan Fund <br /> and-a grant of $1,348,400 from an EPA SPAP Grant. The State agrees monies from.the SRF <br /> loan can be used to expend-on this Alternate which enhances the existing and proposed <br /> systems. Projected-monies from EPA and SRF sources 'can accommodate-the-original and <br /> alternate design because of lower construction bids. The difference between the bid and the <br /> budget is reserved for this alternate project. This alternate design still needs to be engineered, <br /> permitted and:bid-and, if at all possible from a timing standpoint, coordinated into the proposed <br /> project. <br /> The design for this work will begin as soon as a design and construction administrator is <br /> chosen. .A separate_bid for construction will be necessary at a later date. Whether design and <br /> permitting can '-catch up' to the present work is not yet known. 1n any event, this proposed <br /> design enhancement will provide a system that can be more efficiently operated. <br /> FINANCIAL IMPACT: There. is no financial impact from approving the Resolution of Award. <br /> The contract with J.F. Wilkerson Contracting Company is for $2,942,954.46 and has been <br /> accounted for in the County's GIP and is within budgeted amounts. <br /> RECOMMENDATiON(S): The Manager recommends that the Board: <br /> A. Funding <br /> 1. Accept the EPA Special Appropriations Grant Funds for Construction of the <br /> Central Efland & North Buckhom Sewer Improvements (Attachment 1) <br /> 2. Ratify the Resolution noting acceptance of Central Efiand — Phase 2 Northern <br /> Buckhorn Sewer Systems State Revolving Loan (Attachment 2) <br /> 3. Approve Budget Amendment#1-A <br />
