To minimize costs, this work will involve using a ground water flow model that was previously developed to simulate ground water conditions in the Stephenville area d) Determine the number of wells, well spacing, depth of wells, well diameter, and thickness of sand to be screened for the new well fields. e) Conduct site visits to evaluate well fields and potential transmission line routes. f) Identify any particular water quality impacts and maintenance issues expected for each new well field. g) Determine the transmission piping, storage, and booster pumping necessary to deliver the water from each of the areas into the City's distribution system. h) Identify right-of-way options and any permitting issues associated with the transmission system for each option. i) Prepare an estimate of the capital costs, routine annual operations and maintenance costs, and periodic operations and maintenance costs necessary to maintain the production capabilities of the wells in each area. j) Determine a recommended ground water system and prepare maps and a summary write-up describing the system. Task 3 — Surface Water System Development Schedule: Complete within 3 months after Notice to Proceed. 433 Cost: $39,500 a) Identify the construction schedule and the size of storage facilities planned by Upper Leon River MWD. b) Obtain the size, location, and other parameters related to the site at which Upper Leon River MWD plans to deliver water for the City. The delivery location will be the site of the proposed pump station and starting point of the transmission pipeline. c) Evaluate two alternative routes for the surface water to be transmitted from Dublin to the City (i.e., Hwy 377 and FM 847) and develop the best right-of-way alternative, including use of both public right-of-way and private land. This will include on -site evaluations to identify potential fatal flaws that may not be reported by currently available mapping. d) Determine permitting requirements for each alternate route. e) Prepare plan and profile sheets of the two alternative pipeline routes based on USGS 7'/z minute quadrangle maps. f) Perform a hydraulic analysis on two pipeline diameters for the pipeline route alternatives in order to optimize pump station requirements, pipeline costs, and operation and maintenance costs. g) Determine the pump station characteristics (horsepower, system head curves, etc.) associated with each pipe size for each alternative route. h) Prepare a pumping station arrangement for each alternative sufficient to prepare a detailed cost estimate. i) Prepare estimates of capital costs and routine operation and maintenance costs for the four transmission pipeline and pump station options (i.e. two diameters and two routes). j) Prepare maps, diagrams, and a summary description for the recommended surface water alternative. Task 4 — Presentation to Council and Selection of Alternative Schedule: At least two weeks after completion of Tasks 1-3. Cost: $4,000 a) Develop a recommended plan and review with city staff, the water committee, and the city council before finalizing. b) Clarify issues raised by city staff, the water committee, and the city council. c) Make one formal presentation of the recommended plan before the city council. I j 434 Task 5 — Distribution System Analysis Schedule: Complete 2 months after approval of the recommended plan.
