Peter Kaleta , Director of Ronald L. Chernick Public Works Stephen M . Uhlarik Tom Cech , Village Engineer Chuck Henrici ', Fire Chief Dale Wolter , Water Foreman Robin A. Weaver , Admin . Asst Public Works The meeting began at 7 : 08 P.M . by action of Trustee Tosto , the Committee Chairman . WATER REPORT : Chairman Tosto introduced John B . Black , the consultant who prepared the April , 1981 Water Report for the Village , and asked him to sum- marize his findings, Black indicated that the report was prepared with two purposes in mind . The purposes were : l ) To determine what internal improvements were necessary to accept Lake Michigan water . 2 ) To determine the adequacy of the Elk Grove system when the supply will be from Venture rather than the existing wells . Demand, according to Black , should be met by Venture ( Lake Michigan water) first and any further delivery met by pumpage from storage within the Village . Elk Grove Villag.e will have four (4) points , . from which to receive Lake Michigan water . Black disagrees with the Venture suggestion that 8 million gallons of storage are necessary . He feels that 5 . 5 million is adequate as the acquifer is an easily tapp.d underground storage source of water , in cases of emergency . Trustee Chernick inquired as to whether or not wells will be totally terminated . The Director of Public Works , H . Peter Kaleta , responded that in order to attain Lake Michigan water , the Village must phase out all of the deep wells . However , the Village can maintain the wells for stand-by emergency use . John Black recommends that Wells X12 , 9 , 10 (7 or 11 ) and 13 be retained on a stand-by basis . Well #14 could possibly be sold to an industrial /commercial concern or a neighboring community after Elk Grove Village ' s need for it ceases . Well #9 is especially important for stand by use as it is powered by a gas engine and will pump despite electrical power outages . Trustee Tosto strongly recommended that no wells be shut down until quirks in the new Venture system are adequately worked out . In re- sponse to questions by Committee members , Black reassured them that there will be more than adequate storage on the West side of the Village to handle both a peak day and a major fire . Black stated that two considerations . . . 1 ) reliability ; and . . . . 2) economics are the two determining factors in the design of"a 4 Capital Improvements Committee Report Page 2 water system for the Village , Trustee Tosto brought up concerns for the future in asking whether or not the Village will be able to meet demands during an area wide catastrophe in the year 2000 when the population of the area has increased . Black indicated that approximately 67% of average day demands could be met even after water in the reservoirs has run out . The Village ' s water distribution map was explained and examined with regard to points of connection and retained well sites . Venture will pay for the construction of a minimum 12 inch water main down Arlington Heights Road to Biesterfield Road . This one connection point will be fully paid for by Venture . Venture will also be responsible for constructing and maintaining pressure control' stations along their pipeline for Elk Grove Village ' s other points of connection . Since Venture must trasmit water to the communities West of Elk Grove Village , there will be adequate pressure through the Village ' s portion . Chairman Tosto asked Mr . Black for his input on when the Village ' s portion of the work should be started . Black suggested that the Village not commit its resources until the Venture pipeline is half way through the Village . OHe added that it could take Venture up to a year to effectively control and operate their pumping stations . Mr . Kaleta asked for an estimated time allotment for Village work . Mr . Black estimated three months for the design phase and no more than 8-9 months for the construction phase . Fire Chief Henrici brought up concerns about fire protection systems'. Many sprinkling systems are based on and built for a minimum water pressure of 55-60 pounds . If Lake Michigan water does not enter the Village at these pressures , some systems will need to be altered' at the expense of the owners . Lower pressures may also , according to Chief Henrici , increase insurance costs . Chief Henrici asked that the "total " cost should be taken into consideration . In response , Mr. Black stated that it is not economically feasible to increase the pressures as water for fire protection purposes is such a small proportion of the total water needs . At this point , the water pressure of the water from Lake Michigan is not known and is likely to be adequate for all current sprinkler systems . Mr . Black cal - culated that the likelihood of a fire in any one place at the same time as the maximum water usage hour on any of 30 days is 2 . 25 In 100 ,000. Trustee Stephen Uhlarik , referring to Page 9 of the Water Report inquired as to whether or not the 21 . 2 MGD (Million Gallons Per Day ) was a set figure or a negotiable one . Black indicated that the figure was negotiable , that the Village has input in establishing a figure , but that a specific figure cannot be demanded . A MGD figure will be in a contract and the Village will have recourse if it is not met . Current figures are estimates because the entire design of the organization is not set . Trustee Uhlarik requested clarification on the percentage of daily demands which would be met ak Capital Improvemer—s Committee Report Page 3 with a retained facility . Variations will occur based on the time of day but according to Mr . Black , 70% of average daily demand will be met for 3 days with the use of storage , after that , 48% would be available in the year 2020 . Mr Black indicated that this rate is ex- cellent when compared to most cities . The possibility of being with- out a constant supply of Lake Michigan water for more than three days is very unlikely . The most likely source of failure , according to Black , is an electrical outage , for which the Village is equipped with emergency generators at the Pumping Stations . Trustee Uhlarik asked about the estimated $200 ,000 it will cost for , the Village construction work. Public Works Director Kaleta indicated that one reason for the cost being so reasonable was that the Village will have four points of connection , which allows use of the existing transmission network of watermains . • Chairman Tosto thanked John Black for the report and his attendance at the meeting . OTHER BUSINESS : The Waumm et al letter to President Zetteck was discussed . Residents in the area of Forest Lane and Oakwood Drive wrote the letter to complain about the poor drainage at that intersection . Tom Cech , Village Engineer , indicated that it is one of the sites planned for work next year . All members of the Committee agreed that there are sufficient MFT (Motor Fuel Tax) funds ; therefore , this intersection should be added to the other three areas selected for placement of storm sewers . This action will be recommended by the committee at the July 14 , 1981 Board Meeting . The estimated cost is $ 15 ,000 . 00 . The plans for this work will be completed in September of this year . The actual construction work will be com- pleted in late Fall , 1981 . Chairman Tosto directed staff to write a letter to these residents regarding Committee and Board action . Trustee Uhlarik requested that the staff arrange to move the "Road Closed" sign back farther from Nerge Road near Mitchell Trail as it obstructs the view of drivers wishing to make left turns . Commitee memebers asked the Village Engineer and the Director of Public Works to prepare a staff recommendation on the exact points of connection to the Venture pipeline . The meeting was adjourned at 9 : 00 P . M . Respectfully submitted A. &Oka — Robin A . Weaver , Admin .

Black V CAPITAL IMPROVEMENTS COMMITTEE SUMMARY OF MEETING June 30, 1981 1_ Met with our Consultant, John B. Black to discuss his water � report. A. Water demand will be met by the Water Agency (Venture) and delivered at 4 points within the Village. B. Storage of 5.5 million gallons of water, rather than the'8 million suggested by Venture, will be adequate with the easily tapp44 aquifer as a source of water. C. All deep wells will be phased out of use but 5 will be maintained for emergency use. D, There will be adequate storage on the west side of the Villa �o handle both a peak day and a major fire., E. The Water Agency (Venture) will construct and maintain pressure; control stations along their pipeline. F. Work on construction by the Village, in Mr. Black's opinion, should not be started until the Venture pipeline is half way through the Village and the estimated design and construct464%"�' , phases should take about one year. G. Some sprinkler systems may have to be adjusted in the unlikely case that we maintain lower water pressure. d B. Sevlenty-percent of average daily demand for water can big not for 3 days based on planned storage capacity. Other Business: • The Committee will recommend to the Board that storm sewer work be done at the intersection of Forest Lane and Oakwood Drive with Motor Fuel Tax Funds, in addition to the three areas already approved, at an approximate cost of $15,000.00.
