Water Supply Update Mr. Goodrich reported: ■ Average water use for the month of November was 4.11 million gallons per day (mgd). This amount was slightly above November 2011 water use. ■ Injection into aquifer storage and recovery (ASR) #2 is accruing at a rate of about 1000 gallons per minute. To date ASR#2 has approximately 15 million gallons of water stored. Once ASR#2 has reached its targeted storage goal of 200-250 million gallons, the City of Tigard (COT) will begin injecting into ASR#1. ■ ASR#3 is in design. Construction will begin in fiscal year 2014. 5. City of Tigard Future Water Supply Development—Dennis Koellermeier Mr. Koellermeier reported: • The City of Sherwood recently completed the construction of water pipelines and facilities from the Willamette River Treatment Plant in Wilsonville to Sherwood's water distribution system. ■ In order to evaluate future Willamette River water supply scenarios for the Tigard Water Service Area,Tigard contracted with Murray, Smith &Associates (MSA). MSA provided a conceptual analysis of the following scenarios: ➢ Supply development in partnership with Wilsonville and Sherwood. ➢ Major regional supply development with partners. Brian Ginter,P.E., Murray Smith &Associates, Inc. gave a PowerPoint presentation titled the Future Water Supply Development Concept Analysis. The presentation is on file in the IWB record. Presentation highlights: ■ Mr. Ginter discussed the two scenarios. Both would: ➢ Connect the Willamette River supply to Tigard's 10-Million-Gallon Reservoir. ➢ Deliver 25 mgd to the COT in the year 2030. ■ Scenario 1-Supply Development in Partnership with Wilsonville and Sherwood. ➢ Tigard may participate in the expansion of existing infrastructure and buy into excess capacity when available. ➢ Existing infrastructure was built in good economic times, and there is a firm number on the cost, so the potential buy in would be lower than scenario 2. ➢ Total Estimated Project Cost,Year 2030 Dollars - $170.6 million ■ Scenario 2-Major Regional Supply Development with Partners. ➢ Costs and elements will vary depending on the number of regional partners. ➢ Infrastructure is not constructed and is still at the conceptual stage. ➢ Significant transmission costs can be anticipated. ➢ Willamette River Water Treatment Plant expansion would require construction of a new facility running parallel to existing treatment plant. ➢ Potential partners are Sherwood,Wilsonville, Hillsboro,Tualatin and Tualatin Valley Water District (TVWD). ➢ Total Estimated Project Cost,Year 2030 Dollars - $371.4 million Mr. Ginter discussed the different phasing options of the two scenarios. Mr. Koellermeier stated the Lake Oswego partnership is projecting a total project cost of $230 million in 2016 dollars. Tigard will likely be responsible for a little more than 50 percent of this cost. The board discussed Tigard's Charter. It requires Tigard voters to approve the Willamette River supply before it can be used as a drinking water source for Tigard citizens. Mr. Koellermeier stated: ■ The PowerPoint presentation was for informational purposes. ■ The Sherwood/Wilsonville partnership is the most economical scenario. ■ COT will likely need to decide whether to pursue the Sherwood/Wilsonville partnership within the next 18 months. A financial commitment (of approximately$5 or $6 million) would be required if Tigard moves forward with this scenario. ■ Currently COT has no legal obligation to participate in the Sherwood/Wilsonville partnership. 6.
