1. On December 7, 1993, the Board approved a Brown and Caldwell review study on the North Beach/Sea Oaks Plant. The study was approved by the Board'on May 17, 1994. (See attached agenda item and minutes.) 2. On October 11, 1994, the Board approved a Work Authorization with Masteller and Moler for engineering design and construction services for the above -referenced construction project. (See attached agenda item and minutes.) The Sea Oaks homeowners association has expressed great concern over the loss of reuse water for irrigation. The Utilities staff proceeded with the issuance of an RFP for an engineering study to determine the best interim and long-term source of non -potable irrigation quality water for Sea Oaks and other barrier island subdivisions. The RFP was responded to by five firms. A short list was made by the selection committee and ranked during the presentations as follows: 1. Brown and Caldwell 2. Professional Engineering Consultants, Inc. 3. Gee and Jenson For additional information, see attached copy of the RFP. ANALYSIS Through meetings with the Sea Oaks homeowners association, we have come to an agreement that their own irrigation system will temporarily provide on-site non -potable water source until the reuse study implementation can be completed. In light of the operational cost benefit derived from the removal of Sea Oaks from service, we must proceed immediately with the decommissioning of the plant. The possible options to be studied for providing irrigation quality water are identified below: 1. Potable water to supplement irrigation water. 2. Possible routing of one of the North Beach R.O. Plant's production wells to Sea Oaks as an irrigation source. 3. Construction of a dedicated effluent line from the mainland to the beach area, as per our Master Plan; however, this is not scheduled until 2010+. 4. Joint use of the existing John's Island raw water line to provide irrigation quality water to the beach area, the immediate end-user being Sea Oaks. The estimated project cost summary is as follows: Expenditures 1.* Estimated engineering study cost $30,000.00+ Savings 1. Approximate monthly operating cost savings 8,668.00± with Sea Oaks off line * Staff has applied to St. Johns for an Alternative Water Source Grant. Our understanding is that up to $20,000.00 may be available, which would partially fund this project study. The staff of the Department of Utility Services recommends approval of the following actions: . 1. Authorize the immediate disconnection of the Sea Oaks Wastewater Treatment Plant and authorization to commence with surplusing and abandonment of same. 2. Authorize staff to begin contract negotiations with the selected consultant, Brown and Caldwell, for the above - outlined study. AUGUST 5, 1997 B00K 102 PAGE 4213 45
