TIGARD WATER DISTRICT BOARD OF COMMISSIONER'S MEETING Monday, March 25, 2002 Members Present: Norm Penner, Beverly Froude, and George Rhine, Staff Present: Dennis Koellermeier and Twila Willson Visitors Present Paul Owen 1. Call to Order Commissioner George Rhine called the regular meeting of the Tigard Water District Board of Commissioners to order at 7:02 p.m. 2. Roll Call and Introductions Commissioner Rhine called the roll. Mary Stobbe and Bruce Stobbe were absent. 3. Approval of Minutes—January 28, 2002 Commissioner Norm Penner requested correction to Item #5, sentence two, to read Commissioner Norm Penner, not Commissioner George Penner. Commissioner Penner motioned to accept the minutes as corrected and Commissioner Beverly Froude seconded the motion. All voted to accept the January 28, 2002, minutes as corrected. Commissioner Beverly Froude commented on Item #7 of the January 28, 2002, minutes. She was grateful that the water was now drinkable and thanked staff for making phone calls to get the situation corrected. 4. Visitor's Comments—No Comments 5. Intergovernmental Water Board Update— Norm Penner Joint Water Commission —A feasibility study is underway and several public meetings, sponsored by Clean Water Services, have been held but poorly attended by the public. Demand and supply forecasts were being compared. Regional Drinkina Water (Bull Run)Aaencv-Tigard has made its position known and has signed the joint funding agreement to finance the proposed agency feasibility study. The fourteen other agencies were to sign or would bow out. A RFP (Request for Proposal) has been issued to seek a consultant for the study. Several citizen groups have been lobbying to be included as active participants in the on-going planning of the agency. Aquifer Storage Recovery was also discussed at the IWB meeting. Commissioner Penner mentioned the clogging that was under investigation and requested Dennis Koellermeier give an update during his report. Tigard Water District Minutes - 1 - March 25,2002 0 The Beaverton Intertie was to soon go out on bid. City of Tigard staff, Sally Mills, reported on the lead and copper testing required by federal law. Commissioner Penner said Sally gave a very good presentation. At the conclusion of the regular IWB meeting, a presentation by the City of Portland was made on their plans to respond to the federal EPA regulations to address Cryptosporidium. Commissioner Penner commented that the venture sounded costly. Commissioner George Rhine asked if Tigard had any open reservoirs. Dennis Koellermeier said that the City of Portland was the only agency with open reservoirs to his knowledge. Commissioner Penner added that Portland presented four different options, which ranged in cost from $60-$200 million. There would be problems about the treatment facility location and what treatment approaches to use. At this point, Commissioner Rhine skipped to Item 7— Utility Manager's Report. 7. Utility Manager's Report— Dennis Koellermeier Aquifer Storage and Recovery—The water injection was now at about 65% of ASR capacity with the target date to run through April 29th. The ASR well was shut down for about 24-hours due to turbidity issues. Change orders on the project are under 3%. Beaverton Intertie —The construction plans were about 90% complete and should be going out to bid the end of the month. Everything was coming along well and within budget. Due to the high water year, this could allow Tigard to obtain low priced water for a much longer period of time, perhaps even year round. Gaarde Street—The project created a large hole and traffic diversions, but the project is on time with completion of the project the end of the second week in April. Interties with Other Cities—While performing localized flushing for the intertie with Lake Oswego, a valve was inadvertently left open and water was sent to Lake Oswego a day earlier than anticipated. This created turbidity and the City of Tigard received many phone calls. The press release explaining this situation was included in the handout material. There may be a few laundry claims because of this incident. Commissioner Rhine asked for updated information on the November water main break. Mr. Koellermeier stated that almost all repairs have been finalized. The City moved slowly to get bids for the best value and the insurance claim is to be filed. Mr. Koellermeier gave some background about an article in the Portland Tribune on 3/19/02 entitled Group questions consortium for Bull Run. The group mentioned in the article did ask good questions, i.e. cost equity issues. He had concerns that more opinionated people on the board might not like or accept the answers to these questions. Issues include money and if there is an equitable system for Portland to recover some of their costs. The Bull Run is partly a financial investment and is also an emotional issue. Tigard Water District Minutes -2- March 25,2002 The City of Portland has appointed the review board mentioned in the newspaper article. Commissioner Sten has been a proponent and is sincere in listening to citizen's input. The public needs to be educated to understand the issue's pros and cons. Mr. Koellermeier indicated that all the meetings are open to the public and anyone could attend and give comments even though they were not a voting member of the board. 6. Budget Preparations Discussion Copies of the letters that were sent to the previous Budget Committee Members were included in the informational packets. Doreen Hames agreed to continue to participate as a Budget Committee Member for another term. The need for Budget Committee Members was announced at the last Citizen's Involvement Team (CIT) meeting and will be announced again at the CIT meeting next week. The time is approaching when the committee members need to be in place. Each of the board members would try to acquire one citizen to participate on the Budget Committee. Commissioner Rhine would contact David Strauss and try to involve him. 8. Informational Items Informational items were distributed for board members to read at their leisure. 9. Non Agenda Items Commissioner Froude wanted to know what plans were being made to continue conservation efforts now that the drought appeared to be over. Mr. Koellermeier stated that issue is the focal point of the Water Consortium Group. Focus would be made on keeping conservation at the forefront by maintaining a strong program. Rebate programs are planning to be introduced by the City of Tigard, i.e., citizen's who upgrade their house or landscaping to meet certain conservation measure criteria will receive a rebate toward to cost of their conservation upgrades. The conservation message will continue. 10. Set next meeting date The next meeting will be April 22, 2002. A discussion of when to reschedule the May meeting was held with May 20th or 28th as the preferred dates. 11. Adjournment Commissioner Penner motioned to adjourn the meeting, with Commissioner Froude seconding the motion. The vote was unanimous to adjourn the meeting at 7:49 p.m. Tigard Water District Minutes -3 - March 25,2002 It has become necessary for us to resign our seat on the Tigard Water District Board of Commissioners due to health problems. /91//: e 2-- Bruce Stobbe Date /174 Z - /, / /9.-- -2 Mary Stot ` eDate I MEMORANDUM TO: Ed Wegner FROM: Dennis Koellermeier, Assistant PW Director RE: Service Line Pressure Reducing Valves DATE: April 2, 2002 The Water Division currently supplies and maintains pressure reducing valves (PRV, regulators) on the service lines of residential customers in our water service area (including King City, City of Durham and the Unincorporated area of Washington County)that have greater then 80 psi at the water meter. This practice is a carry over of the Tigard Water District. After monitoring our expenses and the impacts of this practice on our daily operations, I am convinced that we need to change our current policy and process to a mode that is consistent with our surrounding water providers and current State law. This report presents the issues involved in this policy change proposal. Codes/ Rules/ Regulations: Our current Tigard Municipal Code 12.10.090, Water-Plumbing-Inspections, states, "... Plumbing should be of high test and first class, and in conformance with the appropriate codes of jurisdiction issuing the building permits, and where pressures may become high, on 5/8"x3/4"and 1"meters, a pressure regulator may be installed at the meter by the City to control varying pressures... the City will not be responsible for damage from varying pressures." The requirement of the installation of pressure reducing valves is outlined in the Uniform Plumbing Code (UPC) 608.2. Excessive Water Pressure, states, "where local static water pressure is in excess of eighty(80) pounds per square inch (552Kpa), an approved type pressure regulator preceded by an adequate strainer shall be installed and the static pressure reducer to eighty(80) pounds per square inch (552Kpa) or less..." This code is enforced by the plumbing department's representatives and is a requirement of the builder/homeowner in which excessive pressure exists. Oregon Administrative Rules for Public Water Systems Chapter 333.61.050, (Construction Standards (9)-(e)) Responsibilities of Water Suppliers, states, "Distribution piping shall be designed and installed so that the pressure measured at the property line in case of Community water systems, or at the furthest point of water use, in the case of a Transient Non-Community water system of the type described in subsection (d) of this section, shall not be reduced below 20 psi." Our legal requirement as water purveyors is to supply a minimum amount of water pressure. Historical Costs: Installing and Maintaining Service Line Pressure Reducing Valves 1999-2000 1. New Installations - 380 water meters installed with approximately 80% of these meters (304) receiving a pressure reducing valve at a cost of$33.00 each. • 304 pressure reducing valves for new meter installation at $33.00 each = $10,032 (Note: Labor and equipment costs being charged to the meter installation.) 2. Repair of Existing -164 service orders for defective/broken pressure reducing valves. • 164 pressure reducing valves replaced (defective/broken) at $33.00 each = $5,412 • 164 hours for UWII averaging 1 hour per replacement at $16.63 per hour = $2,727 • 164 hours for utility vehicle/equipment at $15.00 per hour = $2460 Total cost breakdown for 1999/2000 = $20,631 Historical Costs: Installing and Maintaining Service Line Pressure Reducing Valves 2000/2001 1. New Installations - 596 water meters installed with approximately 68% of these meters (406) receiving a pressure reducing valve at a cost of$33.00 each. • 406 pressure reducing valves for new meter installation at $33.00 ea. = $13,398 (Note: Labor and equipment costs being charged to the meter installation.) 2. Repair of Existing - 152 service orders for defective/broken reducing valves. • 152 pressure reducing valves replaced (defective or broken) $33.00 ea. = $5,016 • 152 hours for UWII averaging 1 hour per replacement at $16.63 per hour= $2,528 • 152 hours for utility vehicle/equipment at $15.00 per hour= $2280 Total cost breakdown for 2000/2001 = $23,222 The total operating cost for two years of this program was $43,853 or$21,926.50 per year. Comparison to Neighboring Water Providers The following water providers were contacted to ascertain how they dealt with this issue. x Pe$ d On der i °; :ine ads,;e., 02 Agency Install Agency Maintains Special Conditions Agency On New Installations Pressure Reducing that Alter Question #1 Valves on Existing Service Lines City of Tualatin NO NO One time, special case City of Hillsboro NO NO Remote taps on high pressure line City of Gresham NO (1) NO (1) YES (1) City of Beaverton NO (2) YES (2) YES (2) McMinnville Water NO NO NO Sunrise Water YES YES Authority Clackamas River YES YES --- Water TVWD NO (3) NO SEE#3 City of Salem NO (4) NO SEE#4 City of Portland NO NO SEE#5 1 — City will install and maintain PRV upstream of meter to protect meter. 2 — City will install and maintain if City modifies existing pressure zone boundary. 3 —TVWD will install if the district altars existing pressure zone boundaries— customer maintains. 4—Only if pressure exceeds 100 psi. 5— Only if pressure exceeds 100 psi, case by case basis. Analysis and Conclusion Tigard Water District historically provided a unique service to its customers by maintaining service line pressure reducing valves and the City of Tigard Public Works Department has continued that practice. The current cost of this program averages approximately $22,000 per year and consumes approximately 160 man-hours or four weeks of a staff member's time. The legal requirements for the installation of service line pressure reducing valves is clearly assigned to the property owner in the Uniform Plumbing Code. The City Ordinance or the Intergovernmental Water Board Rules and Regulations do not assign this responsibility to the City. By providing this service we are treating our customers inconsistently. By providing this service and absorbing these costs into the Water Fund we have created a subsidy, in that not all our customers need this service but all pay to install and maintain them for those that do. The dollars and man-hours that are expended on this program could be redirected to other more pressing tasks that are beneficial to all customers. Changing our current practice presents two areas where customers will be impacted. The first area is on new installations. We view the impact to the customer here to be minimal in that the vast majority of our new customers are contractors building homes. These building contractors apply for a water meter/connection as a part of their building permit application process. It will be a very simple task to notify all new water meter/service applicants of this policy change and the majority will know we are now becoming consistent with the surrounding communities. If a pressure reducing valve is needed, the plumbing inspector will require the builder to install it and the ultimate customer is then consistent with current UPC requirements. The second area of customer impact will be the maintenance of those pressure reducing valves currently installed in the system. Part of our problem in judging the impact of the change is the fact that the City has not historically recorded which services have pressure reducing valves installed on them. We are forced to estimate this number and our Water Supervisors estimate this number to be approximately 8,000. The issue before us is how do we stop providing a service to our customers that we have historically provided while maintaining customer satisfaction. This is addressed in the recommendations. Recommendations Staff recommends: 1. Tigard Municipal Code section 12.10.090 be modified to clarify that all water service plumbing shall be installed per UPC standards and maintained at the owner's expense. 2. The Intergovernmental Water Board's Rules, Rates and Regulations be modified to be consistent with Recommendation #1. Adoption of Recommendations #1 and 2 above will allow the Public Works Department to stop the installation of service line pressure reducing valves on new installations. This will allow our current number of installations to stop growing. These changes should be made as soon as practical. 3. The Public Works Department should adopt a department policy that states our plan to: a. Start on a program that will result in the City stopping its current practice of service line pressure reducing valve maintenance effective July 2, 2003. b. Develop an informational program that will distribute this policy change to our customers via bill stuffers, printed media, website, etc. c. Notify every service call for pressure reducing valve maintenance of our policy change. The Department shall continue to service/maintain existing service line pressure reducing valves until July 1, 2003. • 2001 Summer Water Supply Season -- Retrospective The following "retrospective"describes the conditions we experienced during the 2001 drawdown season and the key management measures we employed to respond. Weather: Water Year 2001 (October 1, 2000—September 30, 2001)was the driest on record in Portland, in Bull Run, and at many other long-term monitoring sites in the region. Only 56.06 inches of precipitation fell at Headworks during this period; normal annual precipitation is 80 inches. This statistic is somewhat misleading, however, because the low annual total was due to extremely dry winter months coupled with normal or above average precipitation during the spring and most of the summer. See graph comparing Water Year 2001 precipitation to median values for 1900-2000. Total precipitation from November 2000 through February 2001 was about 25 percent less than the 42 inches that normally falls at Headworks, while March through June precipitation was about 10 percent more than the normal 24 inches. This trend persisted into July and August with about 40 percent more rain than the usual 21/4 inches. Unusually dry weather returned in September(about half the normal month's rain) and lasted through the first week of October, when the fall rains began in earnest. Snow accumulation in the spring season also helped mitigate the effects of a dry winter. Winter snowpack was well below normal, but began to increase in March as the precipitation picked up. By mid-April, snowpack in Bull Run was near or above normal and remained that way through the late spring melt. We did not experience"heat wave"conditions during summer 2001. Peak day demand was 183 million gallons per day(MGD). In past years (e.g., 1980), we have peaked as high as 230 MGD. Average demand during summer 2001 was 143 MGD. Average daily temperatures during the summer were comparable to 2000, and precipitation was somewhat higher than 2000. Bull Run Supply: Drawdown began on July 3 and ended on October 11. The actual drawdown followed very closely the median projections from mid-June through early September, then tracked the warm-dry forecast during September and early October. The attached drawdown curve shows actual storage conditions (bold line) in comparison to the June 18th projections. From mid-July through mid-September, the projected date for the beginning of reservoir refill (under the median projection)varied from October 6 to October 12. Actual refill took several weeks,beginning on October 11th and completing on November 4th. Streamflow in Bull Run was about 80 percent of the long-term average for most of the summer. In September, streamflow dropped to two thirds of normal in the first half the month and to slightly less than half normal flow in the second half. Reservoir inflow was down to slightly more than 40 million gallons per day(MGD)prior to the October storms that initiated reservoir refill. 4' The Bureau drew approximately 9.9 BG out of storage to meet water supply demands and to provide for downstream releases. In early October,prior to refill,minimum useable storage remaining in the Bull Run reservoirs was about 300 million gallons. Groundwater pumping during mid-October helped increase reservoir storage back to about 1 BG, a threshold used as a management target. Our experience this summer leads us to believe the previously assumed available capacity of 10.2 BG might be too optimistic. Over the winter, the Bureau reviewed the water quality and physical limitations associated with drawing water from storage(e.g., taste and odor problems at low reservoir levels). Based on this review, we chose a new estimate of 9.9 BG for use in the 2002 summer supply plan. A technical memorandum describing the background and rationale for this change is available. Groundwater Supply: The Bureau pumped groundwater during October to augment supply. Pumping began on October 8"'and continued for almost two weeks, ending on October 19t. The total amount pumped was 440 million gallons. The blend ratio was approximately 45-50 percent groundwater to 50-55 percent Bull Run water. Although the blend ratio was rather high,customer complaints to the Water Bureau were minimal, in part due to the short duration of the pumping. Conservation Activities: Portland and the Regional Consortium partners began sending out conservation messages in the late spring in response to preliminary forecasts of dry conditions and lower than normal supply,primarily in the Trask-Tualatin system. West- side water providers invested in additional advertising to get the conservation word out, above and beyond what the Regional Water Providers Consortium sponsored. Highlights of Portland's program included the following: • A summer conservation bill stuffer(beginning in May)—"Help Your Plants Stand Up to the Heat." Messages included addition of organic material to soil to help increase water holding capacity,how to water and care for new plants,use of appropriate watering tools, and maintenance tips. • The"Sprinkler Man"radio ad(August) on many local radio stations. These ads represent a longstanding partnership with the Portland Area Radio Council. • On a single day in August, Conservation staff talked with several hundred people on the South Park Blocks who were attending the Iranian Festival,the Portland Farmers' Market, and the annual summer bread festival. Staff distributed conservation devices and printed information. • Several low income demand management workshops (throughout the summer). These targeted workshops educate customers about the Bull Run as a source of water supply, Bull Run transmission and distribution, how to do minor plumbing fixture repairs, and ways to save water inside and outside the home. Portland also participated in Regional Water Providers Consortium programs including the following: • Radio ads (beginning in May) announcing landscape workshops. Landscape workshops were held at Drake's 7 Dees, Wilsonville Garden Center, Portland Nursery, Farmington Gardens, and Tualatin River Nursery. Radio ads were heard on KISN and KKCW. • Bus sides (signs) and other outdoor advertising around the Portland metro area. "Water. Be resourceful with it."was the featured message. • Television ads in July and August on KATU, KPTV, KOIN, and KPDX. Various Consortium member staff and landscape representatives appeared on featured television segments: In the Garden with Mike Darcy; Fox 49; and AM NW. Messages were geared toward reducing peak season water use without compromising the health and beauty of landscapes. • A new turf care brochure • Consortium conservation information was distributed at Metro's Garden Tour in July, as well as at the landscape workshops. • Salmon Festival at Oxbow Park. Toilet and faucet demonstrations were used to help customers learn about indoor water use issues. Over 8000 people attended the festival and many participated in the Consortium's hands-on booth. • Consortium's web site featured wise water use tips. Particular attention was paid to outdoor watering tips during the summer. Most of the advertising efforts directed listeners/viewers to the"www.conserveh2o.org"website. Regional Coordination: Westside wholesale customers experienced drier spring season conditions than occurred in Bull Run. To assist, the Bureau provided additional water to the Tualatin Valley Water District. TVWD purchased approx. 1.2 BG less water from the Joint Water Commission than originally planned, and increased purchases from Portland by an equivalent amount. The effect on Portland's daily water demand was an increase of approx. 6-7 million gallons per day. This increase was somewhat offset by increased groundwater pumping by Powell Valley Road Water District(approx. 1.5 mgd more in 2001 than in 2000). Fish Releases/Downstream Flows: The Bureau released approximately 1.7 billion gallons of water into the lower Bull Run River during drawdown, and tracked the resulting downstream water temperatures. The daily release amounts were derived using flow release experience from recent previous years and a regression model developed by the Bureau. Approximately 30 cfs (20 mgd) were released during most of the drawdown season. For a few days in August, when the air temperature got hotter, slightly more water(40 cfs, or 30 mgd)was released to keep the water temperature cooler. The goal was to stay under the DEQ water temperature standard for rearing fish(17.8 degrees Celsius, based on a 7 day moving average of maximum temperatures). The temperature of the water released from Dam 2 met the standard. Water temperatures measured downstream at Larson's Bridge did not meet the standard during five separate multiple- day periods during July, August and September. Larson's Bridge is the warmest location on the lower river(at river mile 3.7). It appears, however, that the Bureau was able to manage the flow amount and temperature of the release to reduce the magnitude of the temperature peaks at the bridge. Our 2001 experiences will be used to improve downstream flow management in future years.
