Water District Representatives - General Manager Hoagland and Clerk of the Board Matson. 1. Future Water Sup~ly Issues for the EVMWD Service Area. (F: 164.1) General Manager Hoagland noted that the Board has wanted to meet with the Council for a while, and expressed appreciation for the opportunity to discuss significant water issues. He explained the current water supplies being local groundwater wells producing 9,600 acre feet/year; surface runoff from San Jacinto River Basin (Canyon Lake ) 3,000 acre feeUyeaz; imported water from Lake Skinner (Auld Valley Pipeline) 5,500 acre feet/year; for a total of 18,100 acre feet/year. He e~cplained that there is only about 10 feet of excess water in Canyon Lake. Councilwoman Brinley questioned the current water level in Canyon Lake. General ManagerHoagland indicated it is presently at 1372' elevation. Mr. Hoagland explained the current demands for water, being 36 million gallons per day on peak days . He explained the potential for approximately a 7% loss in water; and noted a situation in the downtown area which was a cost effective approach to the leakage. He explained the complicating factors of ~vater quality and the cost of supplies from the Colorado River. He also explained the level of salts and phosphates in these waters which already exceed the salt discharge level when they purchase the river water. He advised that local ground water is very high quality and low in minerals, but noted problems with water from Canyon Lake. He stressed the balancing act to address these complicating factors. He detailed the availability and cost factors for each type of supplies; and stressed the benefit of using local water. He addressed the future needs and presented graphs for wet and dry year scenarios based on a 3% per year growth rate; and stressed the limitations on the long range supply. He noted that one well on the island has water suitable for their use and explained potential assistance from the wetland project and the Temescal Valley project. He stressed the need for additional supplies by the year 2001 or 2002. He presented a diagam of the Temescal Valley pipeline project and explained the plan to address the needs for the development in Horsethief Canyon. He detailed the back basin runoffrecovery project and stressed that this would be the lowest cost PAGE TWO - STUDY SESSION MINUTE5 - NOVEMBER 5, 1996 alternative for providing the necessary water supply. _/ Councilman Alongi questioned the Eastlake Project Area. Mr. Hoagland showed it. i~ Boardmember Attridge questioned use of water for a golf course. Councilman Metze questioned the ownership of property in the azea. N1r. Hoagland indicated that they do not own the property at this time. He noted that the Eastlake Development will increase the demands on the system by 50%, and they will need to mirigate that impact; and will be discussing that to determine how both parties can meet their objectives. He stressed the potential opporhxnity to use low cost local resources to meet the need. Mayor Pape questioned the depth proposed in the back basin. Mr. Hoagland indicated that there would be no significant changes to the topography, but it could be up to 10 or 15 feet deep. Mayor Pape questioned the possibility of using the area for sailboats. Mr. Hoagland indicated that it would probably be too shallow. Mayor Pape inquired whether this body would go dry in the summer. Mr. Hoagland confirmed that would be the goal and further detailed the project. There was general discussion with regard to the project, water quality and the improvements required to facilitate it. Assistant City Manager Watenpaugh questioned the potential need for excavation and fill to begin this project. Mr. Hoagland confirined that will be needed and expressed willingness to work with the developer to mitigate the impacts on water supply. Boardmember 7effries noted that there has been limited discussion of this topic by the Board, to date. Mr: Hoagland confiuned and explained that this is a component of the water master plan. Mayor Pro Tem Kelley questioned the capacity of the Temescal - Pipeline Project. Mr. Hoagland indicated that the daily capacity will be approximately 26.8 million gallons a day. Boazdmember 7effries noted the total cost for the project. Mr. Hoagland indicated that the worst case scenario for the pipeline is about $30 million in project costs, with an additional $18 million in connection fees. Mr. 7effries noted that part of the problem is who will pay for the project; and suggested it would either require a large development fee or a general assessment. There was general discussion of water sources and the related costs. Mr. Hoagland stressed the cost of imported water. Mr. Watenpaugh questioned the timing for the diversion of water,' and whether the wetland project would be lined. Mr. Hoagland indicated that there would be no lining, but the water would be allowed to sit on the ground without soaking in. Mr. Watenpaugh questioned the potential for trading wetland azeas for this are. Mr. Hoagland noted the difficulties, in that it would not have water yeaz round, but they are working to see what will be the most beneficial approach. 2. Reclaimed Water Use for Level Maintenance in Lake Elsinore. (F:164.1)(X: 92.1) General Manager Hoagland noted that Boardmember Anderson requested this discussion. He stressed the unportance of understanding the scope of watei issues to Lake Elsinore, and addressed the background, requirements, supplies, costs and other issues. He explained the requirement that the Lake be maintained in an operating range of 1240 to 1249, and noted that there is approximately another two yeazs of evaporation in the Lake right now. He noted the Agreement to Fill and Operate and advised that a lot of the issues have been resolved and are being resolved, with the remaining issue being the addition of water to maintain the level. He explained that there is an annual evaporation rate of 14,000 acre feet/year, and stressed tHe impabt of the requirement for body contacY quality water. CouncIlwoman Brinley questioned the level of water quality: Mr. Hoagland clarified that the intent is to use tertiary treated water or a three part process. He explained the three levels, and clarified that'it canbe used for anything but dnnking. He stressed ihat the water is completely disinfected. 1Vlayor Pro Tem Kelley questioned other lakes which aze presently using this type of water. Mr: Hoagland indicated that Lake Irvine and some others are presently PAGE THREE - STUDY SESSION MINUTES - NOVEMBER 5, 1996 using it. Councilwoman Brinley questioned previous parasite problems in that area. Mrs. Kelley inquired if he knew of one with recreation uses. Mr. Hoagland indicated that he did not,. but stressed the wnsistently high water quality levels. Councilwoman Brinley inquired if this was infended as a pilot program: Mr. Hoagland indicated that it was not but noted other pilot programs including one in San Diego to provide treated drinking water. , Boardmember Attridge noted a project in Fountain Valley and stressed the millions of gallons of water a day from tfiat plant. Mr. Hoagland addressed the supply issue, and explained that d~inldng water would require 80% of current total annual production to maintain Lake Elsinore's water level. He further indicated that about 2,000 acre feet of reclaimed water is available from Eastern Water District in 1998; in addition to the EVMWD 3,000 acre feet of reclaimed water. He noted that Eastern will have more available in the future, but only about 30% of the water required is cunently available. He also noted an issue before the Water Board to consider a feasibility study to apply for a NPDES Pemtit to discharge reclaimed water from multiple sources into Lake Elsinore . MayorPape questioned the evaporation rate vs. The water available and questioned where the additional water will come from. Mr. Hoagland concurred that tlvs was an area of concern, He compared the cost for Drinking water of $S million/ Year vs reclaimed water of $.85 million/year. He stressed the difficulty of ineeting the requirements. Councilwoman Brinley questioned how to sell reclaimed water to the public and stressed the honor stories of diseases contracted. Mr. Hoagland indicated that no one has ever gotten sick swimming in reclaimed water, and stressed that it is treated and filtered. Councilman Metze questioned the water in the Domenigoni facility and reclaimed water. Boardmember Anderson indicated that would be drinking water. Councilwoman Brinley stressed the need for a thorough education process for the public. Boardmember Attridge indicated that this has been addressed previously. , Boardmember Anderson stressed that it is a lot closer in timing, than originally anticipated. Boardmember Attridge stressed that the issues should be gone at this point. Councilwoman Brinley reiterated the need to address it as a near future issue. Councilman Alongi questioned what is done with the reclaimed water now. Mr. Hoagland indicated that it is used for agricultural users. Councilman Alongi questioned the safety factors xo.ensure proper purification. Mr. Hoagland stressed the redundancy within the plants to assure adequate treatment and backup systems, and noted that it had not historically been a problem. He also stressed the monitoring factor and the impacts of runoff. Councilman Alongi questioned whether the water would be stored elsewhere before putting it into the Lake. Councilwoman Brinley questioned the monitoring of this water. Boazdmember Anderson indicated that the water is not cunently being used. Mayor Pape inquired whether this suggestion had been discussed with Eastern Water District. Mr. Hoagland indicated that it has been discussed, but there is cunently no pernut to put water in Lake Elsinore. Mayor Pape inquired whether the pipelines will accommodate this future capacity. Mr. Hoagland indicated that in 14 months they will need a place to put the water from the pipeline. Councilwoman Brinley inquired if the intent was to buy and store reclaimed water in the Lake; and the future potential that they would sell the water from the Lake. Assistant City Manager questioned the Fill and Operation Agreement which requires that the City pays for one-half of the fill water. Mr. Hoagland confirmed, and explained that he hopes that the reclaimed water will make the level a non-issue. Councilman Alongi questioned what would be done with the excess reclaimed water. Mr. Hoagland indicated that they would send it down stream. Councilwoman Bririley questioned when the process would start. Mr. Hoagland indicated that it would take almost two years to get ~ discharge perrnit; which would probably be about the right timing to address th ; neeJ. `~h:.r~ was general discussion with regard to Council concurrence on placing rec:vn ~u v~:z}ar in the lake and discussion of the concerna for recreational uses. There v~a~ emnhasis ~l~.ced on the joint interest and impact of the lake. Boardmember Ander~on-sfress. ~ t'~° neeii to ~et the study going to meet the needs in the ne3rt two yeazs. Boari;r::.;mberAttridge suggested concunence of the boards. Boardmember Wicke clari`~ec! the import:zr.~r; of the study to PAGE FOUR = STUDY SESSION MINUTES - NOVEMBER 5, 1996 start the process; and indicated that Council would be asked to agree with starting a study. Mayor Pro Tem Kelley questioned the potential for a special education project. Boardmember Anderson suggested consideration of tours of the plant to assist in this area. Councilman Alongi stressed the responsibilities of the water district. Boazdmember Attridge stressed the education effort which has been made previously. Boardmember Anderson further discussion tours of the plant to show the processing and the changes in the water. ' Mayor Pape questioned the nitrogen and phosphorus levels of the water to be dischazged. Mr. Hoagiand explained the remova} of nutrients from the reclaimed water; and indicated that he believes that the questioned has been answered through tests and results. He detailed the recent obsecvations with regard to lake algae, lake turnover , the presence of various nutrients and the problems in removing these substances. Mr. Hoagland explained the need to compile this information into a model to see the impacts of phosphorous on the lake. Mr. Hoagland noted that a large part of good quality water as a result of the 1995 winter exchange of water; and noted that is needed on a more regular basis. He stressed that the whole point of lake management was to cause more frequent spilis from the iake and dilution of the sediments. Councilwoman Brinley stressed,the need to educate the public on reclaimed water and give them a comfort level with the program and assure that all precautions have been taken. Councilman Metze noted that much of that is both bodies showing the same thing. Boardmember Attridge commented that it is impossible to educate everyone, but the education process is still importanf for other agencies and both boards. Councilman Metze concurred that it is important to put forththe effort. Mayor Pape'noted a recent effort to put reclaimed water in the Newport Bay. Mr. Hoagland advised that is still an issue, but partially misinformation. Boardmember Attridge indicated that the back basm is polluted all the time. City Treasurer Knapp questioned studies on channel fish and algae.' Mr. Hoagland concurred that much research has been done in this area and most fish don't like the type of algae in the Lake. He noted unsuccessful efforts to find a nauve fauna to help control the algae. Mr. Knapp questioned the possibility of plants to assist with this effort. Mr. Hoagland e~cplained that would require thousands of acres of plants. He noted the difficulty of the heavy rain and upstream flows over a short period; and noted previous research with regard to the prevention of evaporation. He stressed that the besY approach would be to pump it up to the treatment plant for processing: The Boards thanked each other for the opporiunity to meet jointly.
