' ID 3 <br /> Assumptions <br /> 1. Model will be provided either in Innovyze's H2OMAP or InfoWater. <br /> 2. Model provided by City is calibrated and contains all necessary pipes, pumps, and <br /> reservoirs with the exception of system connections, planned changes in the vicinity of <br /> Reservoir 2 and Reservoir 4, and the changes currently being implemented to serve the <br /> Tulalip area. <br /> 3. Calibrated Alderwood, Mukilteo, and Silver Lake models are included. <br /> 4. The analysis will be performed assuming steady-state system conditions. <br /> 5. Model validation is achieved if model and observed results for pressure agree to within ±5 <br /> psi. <br /> Deliverables <br /> 1. Updated calibrated hydraulic model capable of simulating the Everett Water transmission <br /> • <br /> and distribution systems in both steady state and extended period modes. <br /> 2.
