6.5 Deliverables 1. Technical memorandum summarizing the water supply requirements and providing technical details of data, methods and results. 2. Chapter for CWP covering water supply requirements at a more summary level. Task 7 Conservation Program 7.1 Objective Prepare draft and final CWP chapter describing historical, current, and future water conservation programs. Assist the City match its state-required process of updating water-use efficiency goals with practical and economical options for conservation program implementation over the next 10 years. 7.2 HDR Services 1. Document the City's compliance with water-use efficiency requirements from WAC 296-290. 2. Document the City's implementation of the water conservation program for years 2013-2019, as described in the 2014 Addendum. 3. Meet with City staff twice to discuss the City's existing conservation goals and to determine the desired approach to updating them for the next ten years. The updated goals should reflect the requirements of WAC 246-290-800 and will ultimately need to be adopted by the City Council and EWUC. 4. Determine the conservation avoided cost for the Everett water system. This will follow the method developed for the previous CWP and Addendum to determine deferred capital costs, energy savings, wastewater savings (including pumping costs), and chemical costs for drinking- water treatment. Prepare a technical memorandum summarizing this analysis and its conclusions. 5. Evaluate up to 15 water-conservation measures commonly used by municipal water systems in the western U.S. Measures will be characterized in terms of water savings and costs, for both year-round and the summer-season. Results will include total savings, total costs, and costs per hundred cubic feet of water saved. The analysis will be split into savings and costs for: a) Everett retail and b) EWUC utilities (in aggregate, not individually). Prepare a technical memorandum presenting the results of the conservation measures analysis. Use results to inform the goal-setting process discussed above. 6. Assist the City in estimating and documenting distribution system leakage, consistent with WAC 246-290-820. 7. Assist the City with public involvement activities associated with the approval process for the new conservation plan. This will include preparation of a fact sheet on the updated conservation goals and associated conservation program, and participation in up to two public meetings to meet the"consumer meeting" requirement of 246-290-830.
