Water System Master Plan Presentation Mr. Koellermeier introduced Senior Project Engineer Rob Murchison. Mr. Murchison introduced the Corolla Engineering team, Nikki Pozos and Dave Kraska. After the IWB presentation, the Water System Master Plan will go to the Tigard City Council for adoption. The Powerpoint is on file in the IWB record. Some information clarified during the presentation is as follows: • The volume in ASR 3 is 2 to 2.5 million gallons per day recovery. • Tigard has terminated the partnership agreement with the Joint Water Commission and are now a wholesale customer able to purchase water if needed. • The Corolla report is at the 50th percentile, the average projection or the midpoint; this is not a worst-case or drought year scenario projection. Tigard would implement mandated curtailment activities for severe climatic change. The City has two days of storage for emergency use with the current reservoirs at average daily demand; this does not include the future Cash Reservoir. • The report incorporated stepped up conservation. Corollo examined prior year's per capita usage and noticed a big reduction. • Corolla did not take into account the additional 6 mgd from the lake Oswego-Tigard Water Partnership expansion because we are not under contractual obligation. If we could acquire the additional 6 mgd, it would take us to 2040. • Many of the older pump stations could be taken out of service because the older pump stations are low capacity. The network of piping could be designed to have a lot of little pump stations lifting the water from one to the next or replace little pump stations with one reliable, modern designed station that is accessible at ground level and does not have confined space entry and maintenance issues. • The new pump stations are built to have a high level of reliability and redundancies so there is still enough capacity if one pump went out. Maintaining old pump stations is a major maintenance hassle and the capacity is so much smaller than what is needed. • Hi Tor pump station capacity is good, however it does not have great reliability nor is it in the best condition. It will be one of the last ones replaced. • There are not a lot of pipes in poor condition that need replacing now. Properly installed cast iron ductile pipes will last a long time and the Tigard area pipes are made of ductile iron. Pipes that have problems are made of pvc or asbestos. As redevelopment happens (i.e., Burnham and Main Streets), older pipes will be replaced. • Security is addressed while doing projects. For instance, when existing reservoir projects are proposed, all hatches are retrofitted for greater security including alarms; and reservoirs are closely evaluated for other security measures, such as air vents. • The telemetry system was updated in 2005-06. It is a dedicated, wireless radio. When new sites are built, they are connected to this telemetry system. • Tigard has water pipes under Bull Mountain Rd; however, COT does not have the $2 million to complete the improvement shown in the Master Plan. Washington County is paving the road starting Monday. This is the most likely route of the pipeline. COT is looking at alternative routes to avoid that route since it will be two to three years before we can build the pipeline. • A seismic evaluation was completed four years ago. COT does not have enough money to do all the seismic upgrades. When we are working on a reservoir, we do a seismic Intergovernmental Water Board Minutes April 14,2010 2 1 evaluation and figure out its vulnerabilities as part of the project. We did a vulnerability assessment that identified the most critical facilities; this is where we will spend our money first. Mr. Murchison, Ms. Pozos, and Mr. Kraska David departed at 7:00 pm. 6. Proposed City of Tigard Water Capital Improvement Plan (CIP) Budget Mr. Koellermeier said the CIP budget had not been completed by the City's finance department. 7. Water Supply Update • Mr. Goodrich reported that water demand is currently 4.3 to 4.5 million gallons per day (mgd). COT is still injecting into Aquifer Storage and Recovery (ASR) 1. This will be completed by June 3. The goal is to reach 120 million gallons in storage. • COT is contracting an additional .5 mgd from Portland Water Bureau (PWB) at a summer interruptible water supply. This water will be sold to us at about 66% of wholesale cost for the 60-day period from July through August. This is the maximum capacity we have in our pipeline from PWB. S. Process of How to Amend/Transfer Groundwater Registration Modification Mr. Goodrich reported that the minor changes requested by TWD were accomplished. Staff requests Member's sign the modification to get it to the Oregon Water Resources Department (OWRD) by the April 25th deadline. 9. Informational Items a. Update from Commissioner Buehner on Lake Oswego/City of Tigard Oversight Committee activities • Commissioner Buehner reported that the oversight committee survey results commissioned by the public outreach program came back positive as far as attitudes, water supply quality, understanding of where their water comes from, what was known about the new project, if they knew their water rates were increasing, etc. Our citizens are more informed than citizens in other areas, think the water system is great, and understand what is going on. However, there was not a lot of support for higher rates. • They have been interviewing applicants to do the water rate study and system development charge update to determine how to finance improvements for the Lake Oswego plant. The committee recommended two firms to go to the next level of interviews on April 201h. The consultant will be hired shortly thereafter. The new rates need to be in place by Jan 2011. b. Update from Commissioner Winn on West Bull Mountain Technical Advisory Committee Activities • Commissioner Winn reported the focus was on transportation this month. There was not any discussion related to water. 10. Non-Agenda Items • Commissioner Winn would like Mr. Goodrich to schedule another tour of the Lake Oswego water treatment plant for the IWB, TWD, and anyone else who would like to be included. • COT will distribute an updated IWB roster once the new Durham representative is appointed. Intergovernmental Water Board Minutes April 14,2010 3 • Commissioner Henschel would like to be added to the IWB agenda to give updates regarding the citizen sounding board. • Mr. Koellermeier stated there are several boards with a lot of information. He suggested we deal with them all from a technology standpoint. COT can email or create a website for projects schedules, information, etc. • Commissioner Winn would like the IWB to pay attention to the Robert's Rules of Order- no side conversations. • Commissioner Buehner announced that when COT gets the new rate study on board, they would give a joint presentation to IWB, Tigard City Council, and Lake Oswego City Council on June 15. She invited the TWD board members to listen to the presentation. • Ms. Gaston stated that May 12 is the next IWB meeting. The regular June meeting has been cancelled so the IWB can attend the June 15 meeting with the councils. • Commissioner Henschel inquired about the status of the [GA. Commissioner Winn informed the Board that COT has sent it to legal. Durham and King City are waiting until COT does their legal review. Commissioner Henschel says TWD will begin reviewing at their board level and may take to legal before COT finishes their legal review. Commissioner Buehner would like to know when the attorneys will get it back. Mr. Koellermeier will inquire and let the IWB know. 11. Future Agenda Ifems • Future agenda items were not discussed. 12. Next Meeting: • June 15, 2010 at 6:30 p.m. Tigard City Hall, 13925 SW Hall Blvd, Tigard, Oregon 13. Adjournment At 7:23 p.m., Commissioner Stone motioned to adjourn the meeting; Commissioner Henschel seconded the motion. The meeting was adjourned by unanimous vote of the Commissioners present, with Commissioners Buehner, Henschel, Stone and Winn voting yes.
