The hydraulic distribution system model will be a tool the City can use to evaluate system performance, identify deficiencies, and simulate potential improvements. The study will result in a comprehensive plan to guide planning and investment decisions related to system rehabilitation, replacement, and expansion. Task 1— Population and Service Area Growth CH2M HILL will develop water service area population projections based on current data and forecasts from the U.S. Census Bureau, the Wisconsin Department of Administration, and the Wisconsin Demographics Service Center for two planning horizons: 5 -year and 20 -year. Using the City's geographic information system (GIS) and the City Department of Community Development Comprehensive Plan 2005 - 2025, CH2M HILL will prepare water service area maps . to establish boundaries for system hydraulic analysis of current and potential future conditions. Task 1 will include a project kick -off meeting to charter the project team and confirm the goals of the hydraulic model and planning study. Task 1 findings will be summarized in a chapter of the planning study report. Task 2 — Water Requirements CH2M HILL will review customer water demands and pumpage over the past 25 years. Using historical data and the projections for population and community growth, future water requirements will be estimated. Review of historical data will include metered water sales, water pumpage, non - revenue water, per capita water usage, demand peaking factors, and seasonal demand fluctuation. Detailed billing records for the past year will be collected in preparation of the model development. Estimated future water demands will be prepared for residential, commercial, industrial, and public customers. Future water demand projections will also be prepared by pressure zone. Task 2 data review and water demand forecasts will be summarized in a chapter of the planning supply report. Task 3 — Existing Water System Facilities Using the City's GIS, 2009 Annual Report for the City of Oshkosh Water Utility to the Wisconsin Public Service Commission, and facility drawings, CH2M HILL will tour all the distribution system facilities with the City's head operator to gain an understanding of system operations and constraints. CH2M HILL will prepare a summary of the existing water system components. The overview of the existing water system will include a description of pumping and storage operating strategies. CH2M HILL will prepare an existing system water schematic to depict existing storage facilities, pump stations (High Lift Pump Stations at the Water Filtration Plant and the Washburn Booster Pump Station) and hydraulic grade lines. System standby power will also be summarized in this task. Near the completion of Task 3, CH2M HILL will lead a project meeting with the City to review the findings of Tasks 1, 2, and 3 prior to submission of draft report chapters. Task 3 information will be summarized in a chapter of the planning supply report. Task 4 — Develop Hydraulic Distribution System Model CH2M HILL will develop and calibrate a hydraulic model of the existing water distribution system using the City's GIS and other system data. Task 4.1 Model Software Selection CH2M HILL will provide a summary of the functionality of the two major commercially available software products, MWH Soft's InfoWater and and Bentley's WaterGEMS. CH2M HILL will consider other software platforms such as DHI's MikeNET or MWH Soft's Infoworks DS at the City's request. CH2M HILL will provide the City easy -to- understand guidance on selecting software. Software demonstrations by the vendors will be arranged if desired. As part of this subtask, CH2M HILL will facilitate a meeting with the City to discuss software selection criteria, cost structure and attributes of widely -used hydraulic distribution system hydraulic modeling software. Task 4.2 Model Development The City's GIS will be used to build the model to enable streamlined future model updates. As the GIS is revised and enhanced, the model will need to be updated. The model will include the following physical water system characteristics: length and diameter of the water mains, pipe roughness coefficients, ground elevations, characteristics of pumping and storage facilities and water demands. The City will provide all the facility information to build the model, such as pump curves, storage elevations and control valve information. The hydraulic model will be built as an extended period simulation model which will include all pipes in the distribution system. Task 4.3 Model Calibration, Documentation and Installation Prior to using the model, it will be calibrated so that model input data can be adjusted to accurately simulated measured field conditions. Flow and pressure tests in the field will be performed to calibrate the model to confirm that it accurately simulates actual conditions. Hydrant flow and C- factor tests will be performed to gauge the relative internal pipe condition and to adjust the modeled pipe roughness coefficient to achieve model calibration. Twenty hydrant flow tests and four C- factor tests will be completed. The model will be calibrated to within 5- percent of 90- percent of the data points. A summary of the Task 4 field test data will be included in a draft chapter of the planning study report. CH2M HILL will prepare a Distribution System Hydraulic Model Documentation Technical Memorandum to document the details of the model development. The technical memorandum will be included as an appendix to the planning study report. CH2M HILL will assist the City with installation of the model software. Task 5 — Water System Evaluation CH2M HILL will use the calibrated hydraulic model to evaluate existing water distribution system characteristics and identify deficiencies for existing and future conditions. Evaluation of water system pressures will consider the Wisconsin Administrative Code requirements, the demands of customers, and the City's level of service pressure goals. In addition to system pressure, fire flow demands throughout the system will be considered. Fire flow requirements vary with the physical characteristics of the areas to be protected. CH2M HILL will estimate fire flow requirements at each node in the model based on type of land use and in accordance with Insurance Services Offices (ISO) best practices. Scenarios will be run to evaluate fire flows during maximum day water demand for existing, 5 -year and 20 -year planning horizons to locate areas with insufficient flows or pressures. Water supply reliability (storage and firm pumping capacity) of each pressure zone will also be evaluated and potential deficiencies identified. CH2M HILL will facilitate a workshop with the City to review system deficiencies and brainstorm potential improvement projects. Task 5 analyses and system deficiencies will be summarized in a chapter of the planning study report. Task 6 — Water System Improvements CH2M HILL will identify alternative water system improvements to address deficiencies identified for the 5 — and 20 -year planning periods. Improvements may be capital projects (like main replacement) or new strategies for operations (like pumping changes). Recommendations will be made to reflect phased improvement implementation over the next 20 years. Potential capital projects will be simulated with the model to demonstrate effectiveness. CH2M HILL will lead a workshop with the City to review and select candidate improvement projects for cost estimating and consideration in the City's CIP. Task 6 analyses will be presented in a chapter for the planning study report. Task 7 — Capital Improvement Plan CH2M HILL will prepare planning -level cost estimates for the improvement projects and a work with the City to prioritize and schedule phased project implementation over the planning period. The City's overall Capital Improvement Plan and future development plan will be considered to take advantage of potential efficiencies often offered by future concurrent projects. Task 7 recommendations, cost estimates, and schedule will be presented in a chapter of the planning study report. Task 8 — Planning Study Report CH2M HILL prepare a report including the comprehensive chapters drafted for each task, a report introduction, and an executive summary. A draft report will be submitted for City review. CH2M HILL will meet with the City to discuss the City's review comments of the draft report in preparation for submitted a final planning study report. Ten paper copies and one electronic PDF copy of the final report will be submitted. CH2M HILL will prepare a presentation to City Council members to provide an overview of the project goals, scope and findings.
