Phase I Phase I water improvements would consist of'the construction of an 8 inch water line from 8th Street south along 20th Avenue to Oslo Road, approxi- mately 10,6:00 feet, and the extension of the 20" waterline from 18th Ave- nue to 20th Avenue, approximately 460 feet. 'By constructing these water lines, water service would be provided for the Ixora Utilities Service Area. See attachment 2 which was prepared by our consultants for the proposed scheduling of this work. Also included in Phase I, would be the purchasing of the Treasure Coast and Ixora Water Utilities. Please note that the required waterline connections to the Treasure Coast Utilities had already been made under Contract Part I of the original South County Water Treatment System. The estimated construction cost of the 8" and 20" waterline extensions is $87,890 and -the engineering cost based on the FmHA fee curves will be $5,410 for design and construction surveillance. Phase II Phase II of the proposed water improvements would- consist of the expan- sion of the South County Water Treatment Plant and additional water dis- tribution lines. The exact expansion size and extent of the distribu- tion will be determined once a detailed cost evaluation has been com- pleted of the monies available for the expansions. Once the evaluation is completed, our consultants will present a proposed schedule of the implementation of these funds to the Board for their evaluation and approval. Also included in Phase II of the proposed water improvements is the ne- cessity of the Well Field expansion. This work included the addition of a raw water well along with the inter -connecting piping to the water treatment plant and the associated hydrogelogical consulting expenses. B. Wastewater Improvements The wastewater improvements will consist of the purchase of the Trea- sure Coast and Ixora Wastewater Utilities, the abandonment of the existing wastewater treatment plants and the construction of new pump- ing stations and force mains. The new facilities will transmit the wastewater to Indian River County's treatment facility at Vista Royale, In order for this work to be completed in accordance with the Consent Order issued.by the DER, our consultants have prepared an implementa- tion schedule which should be followed in order to meet the required specified time period in the order. See attachment 2. The cost of these improvements is $733,622 as outlined in the FmHA loan application. Recommendation & Funding 1.
