The committee discussed the possibility of requiring individual metering upon change of ownership or when units are converted to condominimums. This subject will be studied further by the Water Committee and some changes may be recommended in the near future. WINDY GAP: The water needs report prepared by Engineer Robert Kemp of DMJM— Phillips-Reister-Haley dated July 24,1980 was discussed at length by the committee. The committee was informed that Mr.Kemp had not considered the augmentation suit or the reuse factor when preparing the report. After considerable discussion the committee decided to hold a special water committee study meeting with Mr.Kemp and Mr.Larry Simpson of the Northern Colorado Water Conservancy District in attendance.The non committee members of the Board of Trustees will also be invited to attend. COLORED WATER COMPLAINTS: The attached letter dated November 13,1980 from DMJM-Phillips Reister-Haley,about the subject of colored water and excess turbidity was discussed by the committee.Superintendent McCracken explained the step he was taking to help eliminate this problem. WATER RATES: The committee recommends to the Board of Trustees that an ordinance be prepared to implement the l0 increase in water rates effective the January meter reading and that the new tap fees be effective January 1,1981.Copies of the proposed new rates are attached to these minutes. ALONZA R.KORLER: Mr.Kohier has requested the water department construct a new winter water line to his property in exchange for a water tap #3-566-13-00. The committee recommends this exchange not be approved. 0 0 BRADFORD PUBLISHING CO.,DENVER R E C 0 R D 0 F P R 0 C E E D I N G S Water Committee -November 13,1980 -Page Two (2) BIG THOMPSON PLANT DRAIN LINE: Superintendent McCracken reported he has completed the installation of the Big Thompson Drain line to a point east of Highway 7. Superintendent McCracken will work with the Recreation District in regard to the balance of this project. REPORTS: 1.The augmentation suit will be in court again on November 20th at 11:30 A.M. 2.Mr.James Bissell’s application for water on Devils Gulch was reported to the committee.Mayor Tregent has informed Mr. Bissell of the Town’s water extension policy. 3.A property owner in Country Club Manor has requested a fire plug be installed near his residence,Superintendent McCracken will examine this request and report to the Public Works Committee, There being no further business,the meeting adjourned. ‘-)i ‘AL Li JoanJan Horn,Town Clerk — U NOV 24 1980 — 0 WATER RATES —1981 fl URBAN PRESENT PROPOSED RURAL PRESENT PROPOSEL Up to 2500 gal.each mo.$7.42 $8.16 Up to 2500 gal.each mo.$12.015 $13.22 Per 1,000 gallons in excess of 2,500 gallons Per 1,000 gallons in excess of 2,500 gallons $1.90 Pumped—flow rates in addition to the above each month $3.405 $3.75 Pumped—flow rate in addition to the above each month $3.405 $3.75 Per 1,000 gallons in addition to the above in excess of 2,500 gallons $.07 TAP FEES —Effective January 1,1981 Per 1,000 gallons in addition to the above in excess of 2,500 gallons $.07 For a single family dwelling having forty fixture values or less: 5/8”connection Water Rights Fee (40 Values) Tapping Materials 5/8”meter Remote reader Filing Fees (rural only) Additional fixture values 1980 1981 SIZE 5/8”or 3/4” 1” 1¼” 1½” 2” 3” 4’, 6” 960.00 1,705.00 2,665.00 3,840.00 6,830.00 15,365.00 27,315.00 61,465.00 1,005.00 1,785.00 2,790.00 4,020.00 7,150.00 16,085.00 28,595.00 64,346.00 $1.17 $1.29 $.2.09 $.08 $.08 960.00 1,500.00 55.00 40.00 17.00 6.00 2,578.00 1,005.00 1,430.00 55.00 40.00 17.00 6.00 2,553.00 CONNECTION CHARGES BY SIZE 37.50 35.75 C Orley 0.Phillips c .O Senior Vice Presidentt2r.

Richards of the Boulder Water Department and we have the following comments: 1.We believe the water sampled meets the requirements of the Colorado (and EPA)Primary Drinking Water Regulations. While not all the tests were run to show compliance with the primary regulations,Estes Park’s water has,in the past,been in compliance and we have no reason to believe it was not in compliance at the time the tests were run. 2.The water sampled,however,did not meet the EPA Secondary Drinking Water Regulations in several respects.Two things must be kept in mind about these secondary regulations. First,they do not go into effect until January 19,1981; second,they are not enforceable at the Federal level.They have been issued more as guidelines,but they may be adopted by the States as part of their overall drinking water regulations. The secondary regulations are more nearly aesthetic items than they are matters relating to public health.The contaminants that exceeded the secondary regulations were: Measured Value EPA Secondary Regulations Worst of 6 Color 60 41.6 15 Units pH 5.24 5.42 6.5 -8.5 Iron 1.23 0.77 0.3 mg/L Copper 1.1 0.31 1.0 mg/L A Subsidiary of Suite 700 PlanningDaniel,Mann,Johnson,&Mendenhall 910 Fifteenth Street Architecture Denver,Colorado 80202 Engineering Telephone:303/892-7300 Systems Cable:DIMJIM Denver Economics Town of Estes Park November 13,1980 Attn:Mr.Dale G.Hill Page 2 3.Two of the three locations complaining of colored water showed significantly higher levels of iron and copper than the average. Iron and copper are the two most widely used plumbing materials. It is to be expected that the low-pH,relatively soft water would cause some of the metallic piping material to go into solution.Why this takes place more at some customers than at others is difficult to say without considerable detailed investigation. This condition is not something new.In August,1978,a green-stained wash cloth from a motel on Highway 7,which was analyzed for us by the Denver Water Board lab,showed an extremely high level of copper in the green stain. We have speculated that the mildly aggressive characteristics of Estes Park’s water may be aggravated in some buildings by electrolysis set up between dissimilar piping materials such as copper and galvanized steel that have been connected together directly without a dielectric coupling;or by stray electrical currents caused by a defective electrical device in the building which allows some current to flow into the building’s electric system ground which is connected to the building’s water lines. The solution to the first is to see that dissimilar piping materials are separated by a dielectric coupling or insulating bushing.These are standard plumbing items.The solution to the second is more difficult.It involves temporarily disconnec ting the building water service line,probably at the meter,and measuring the electrical potential between the house plumbing and the outside water service line.If there is an electrical potential then either the defective electrical device,if it can be found,should be replaced or the house electric system should be grounded independently of the water line with grounding rods. 4.The water analysis by Mr.Richards does not indicate to us that any major chemical change has taken place in Estes Park’s water.Except for the values of copper and iron (which seem to vary from one building to another)this analysis is similar to the analysis made in August,1978.
