a36 TUESDAY MAY 8, 1984 On April 24 the Authority received a recommendation from its engineers of an alternate approach to the diversion proposal. In this instance it would provide relief to both the City and the Authority and would adequately serve to assist both jurisdictions as a short-term solution to their needs, as well as provide flexibility in operations of the City's treatment facilities and those of the Authority. Accordingly, the Authority unanimously offers the following proposal for Council's consideration: 1. The diversion facilities, including the transmission main, will be designed and constructed by the Authority with a capacity of 3 MGD, now estimated to cost approximately $386,000. The City and the Authority would share equally the initial cost of these facilities on a 50/50 basis. (City's estimated cost = $193,000.) 2. The Authority will allocate and reserve for the City and the City in turn will purchase a 1 MGD capacity in the Authority's Upper Smith River Wastewater Treatment Plant at a cost now estimated to be $1,122,430. This estimate is based upon the City's acquiring 25 per- cent of the present design and approved capacity of the existing treat- ment facility which is 4 MGD. 3. The Authority will design and construct facilities required to expand the Authority's Upper Smith River Wastewater Plant from 4 MGD to 8 MGD capacity when the flow into the said plant equals 90 per cent of the existing plant capacity (4 MGD). The responsibility for the design, construction and financing of this expanded facility will be borne totally by the Authority, unless the City at the time of such expansion elects to purchase additional capacity in the Authority's plant. Should the City elect to purchase additional capacity, the cost for the same will be the Net Local Cost as provided for by the 1974 Sewerage Service Agreement and the terms and conditions of an Amendment thereto, a draft copy of which is attached. 4. The Authority will design, construct and finance sludge handling facilities which are now proposed to the Upper Smith River Treatment Plant. The estimated cost of these additional or supple- mental sludge handling facilities is approximately $300,000. The City will reimburse the Authority on the basis of its prorated share in the existing treatment facilities or at the rate of 25 percent of the cost thereof. The City's share of these costs is presently estimated to be $75,000. 5. Based upon the above, the total estimated cost to the City as described in Items 1 through 4 above is estimated to be $1,390,480. 6. After the Jones Creek Interceptor diversion and force main facilities have been constructed by the Authority, each jurisdiction will have the right to divert one-half or 50 percent of the sewage flows in the interceptor at any given time. The City, because of its allocated capacity in the Upper Smith River Plant of 1.0 MGD, will be limited to this amount. It is recognized that the Authority will coordinate all
