3 <br /> Z <br /> 6. Outline any changes to the City's Operations and Maintenance Program since the 2007 <br /> Plan. <br /> City Responsibilities <br /> 1. Provide any updated information related to water rights, system reliability, regulatory and <br /> operations and maintenance changes since 2007. <br /> 2. Provide any required water quality monitoring data—if data-related changes are discussed <br /> in the plan addendum. <br /> 3. Review and comment on draft addendum Chapters 6, 7, and 8. <br /> Assumptions <br /> 1. The City will provide updated water rights information with any changes/additions from the <br /> 2007 Comprehensive Water Plan <br /> Deliverables <br /> 1. E-mailed Word and PDF files of the draft and final addendum Chapters 6,7, and 8. <br /> Task 7 — System Analysis (CWP Chapter 4) <br /> Objective <br /> Update the system analysis using the existing hydraulic model of the Everett transmission and <br /> distribution system to be used for planning,fire flow analysis, sizing of CIP during design, and <br /> extended period simulations. <br /> HDR Services <br /> Hydraulic Analysis <br /> 1. Begin the task with the hydraulic model that was developed by HDR for the 2007 CWP, <br /> which has subsequently been updated by City modeling staff. <br /> 2. Perform the system analysis using the City's existing model in the H2OMap Water software <br /> by Innovyze. At the City's discretion, HDR can use Innovyze's GIS-based platform, <br /> InfoWater. <br /> Methodology <br /> 1. Receive model from City and load on HDR system <br /> 2. Coordinate with City Operations and Engineering departments to update system <br /> operational information (i.e. pump operation rationale, areas of low pressures, reservoir <br /> operation philosophy, etc.) <br /> 3. Modify the model infrastructure to include modeling of the water transmission system. <br /> 4. Update the model infrastructure to include the changes in the vicinity of Reservoir 2 and <br /> Reservoir 4, as well as changes currently being made to serve the Tulalip area. <br /> 5. Validate the model using information from up to 25 field fire flow test results. Locations to <br /> be used for model validation will be identified by HDR with input from the City and will <br /> represent locations throughout the City's distribution system.
