Acoma St., protested a high bill due to an inaccurate meter reading taken from a faulty remote. John Bock appeared to review the circumstances and his reasons for adjusting the bill. John noted that, as a policy, he arranges to repair the meter or remote and adjusts the bill to a prior comparable amount if the owner responds in a timely manner. The Board recommended the Utilities Department continue to use this policy for billing adjustments resulting from faulty meters and remotes. Bev Bradshaw entered at 5:17 p.m. 3. GNAT PROBLEM -2319 W. HARVARD AVE. The Utilities Department received a letter from Sabin Walker, an attorney for Mr. Bill Miller of 2319 W. Harvard Ave. who is experiencing a gnat problem as a result of standing water. The Utilities Department spoke with Tri-County Health Department and the State Health Department and it was determined that there was no evidence of raw sewerage being discharged and the insects are a nuisance species , not a public health threat. No action was recommended. Mr. Miller was notified by letter. This was for the Board's information only. 4. HOTEL SEWER TAP AGREEMENT -DEN MAR. Den Mar submitted a Hotel Sewer Tap Agreement for their proposed 278-unit hotel to be built at 10325 Park Meadows Drive in Littleton. The proposed agreement has been reviewed and approved by Englewood's City Attorney. Per the Water Board policy established at their August 13 , 1996 meeting, the proposed agreement sets the sewer tap fees at half the standard fee , with no additional tap fees to be collected unless the water usage exceeds the agreed-upon limit of 100 gallons per unit , per day . Tap fees in the agreement total $208,512.50. Mr. Otis moved; Mr. Cassidy seconded: To recommend Council approval of the Hotel Sewer Tap Agreement with Den Mar for a Parkridge Marrida Hotel at 10325 Park Meadows Drive. Ayes: Nays: Members absent: Motion carried. 5. THKAGREEMENT. Wolosyn, Clark, Cassidy, Otis, Kasson, Bradshaw None Higday, Moore, Habenicht Stu discussed the RTD light-rail station that is being negotiated with the McLellan Foundation to be located on a portion of Englewood's McLellan property. A land exchange with RTD for the McLellan property was discussed. The McLellan Foundation will be making a recommendation to City Council in the future. 6. WATER SUPPLY OUTLOOK. The Board received a memo from Joe Tom Wood discussing the water supply outlook for Englewood for the summer of2002 . Joe Tom noted that in a dry year, which this summer appears to be, the low stream flow in the river, together with the demands for water from senior rights, might result in the City's senior river rights not being able to provide the City with all of the water needed. Englewood can eliminate water shortages by drawing water from McLellan Reservoir, utilizing the Bear Creek augmentation plan or diverting reusable wastewater return flows from the river. Stu noted that if alternate rights were going to be used, the plan would be reviewed with Council. 7. CENTENNIAL AGREEMENT FOR TEMPORARY LEASE OF RETURN FLOWS. Centennial owns reusable wastewater return flows to the S. Platte River and Englewood has means to re-divert these flows at Union Avenue and either use them or redeliver to Centennial. The proposed agreement would divert the return flows and pay Centennial $85 .00 an acre-foot for the flows, plus pumping costs. Centennial would acquire all return flows delivered to McLellan Reservoir that are not acquired by Englewood and shall pay Englewood $30/acre foot , plus pumping costs. Mr. Kasson moved; Mr. Otis seconded: Ayes: Nays: Members absent: Motion carried. To recommend Council approval of the Centennial Agreement for Temporary Lease of Return Flows.

Camp, Dresser & McKee prepared a response to Mr. Dounay' s questions regarding the use of chloramines. Stu noted that Mr. Dounay' s questions were good questions and the responses can be used for future inquiries. A letter with the responses was mailed June 11, 2002. The meeting adjourned at 5:58 p.m. The next Water and Sewer Board meeting will be Tuesday, July 9, 2002 in the Community Development Conference Room. Respectfully submitted, Cathy Burrage Recording Secretary A 77. 2 SECOND EXTENSION OF WASTEWATER TRANSMISSION AGREEMENT THIS AGREEMENT, made and entered into effective as of May 16, 2002, by and between SOUTH AR.APA.HOE SANITATION DISTRICT, a quasi-municipal corporation, hereinafter called "SOUTH AR.AP AHOE"; THE BOARD OF COUNTY COMMISSIONERS OF THE COUNTY OF A.RAPA.HOE, a body corporate and politic of the State of Colorado, hereinafter called the "COUNTY"; the CITY OF ENGLEWOOD, Colorado municipal corporation. hereinafter called the "CITY"; SOUTHGATE SANITATION DISTRICT, a quasi- municipal corporation, Arapahoe and Douglas counties, hereinafter called "SOUTHGATE"; and WASTE MANAGEMENT OF COLORADO, fNC., a corporation. hereinafter called "WMC".

The SolarBee is a unique solar-powered circulator for lakes , dams, drinking wate r impoundments, stormwater reservoirs and other large bodies of water. The SolarBee Model 1 OOOOF , w ith its 36" diameter intake hose , circu lates and renews the surface of the reservoir at 10,000 gallons per minute in full sun light. The result is that the 5,000 horsepower per acre of solar power which strikes the body of water is put to much greater use throughout the water column for revers ing eutrophication and breaking down pollutants . The SolarBee offers these exciting benefits for improving water quality in large reservoirs: * No energy or other ongoing costs. * Reduction or elimination of chemical additions for controlling algae or precipitating phosphorus . * Increased dissolved oxygen and higher pH to much greater depths in the reservo ir . * More precipitation of phosphorus as apatite , more gassing off of ammonia. * Reduction or elimination of taste and odor problems as blue green algae control is achieved. * Better water clarity as the gentle mixing causes more bioflocculation. * Better fish habitat since the d issolved oxygen levels typically go up in the cold water zone below the treatment depth as set by the intake hose . * Large volume of influence, up t o 2,000 acre-feet of water per machine, depending on water conditions and the depth to which the intake hose is set. * Works in all climates , from desert conditions to ice , and for widely fluctuating water levels. * Various financing options are avai lab le. And our rent-to-own program which allows the owner to test the SolarBee in actual field conditions for one or more seasons before comm itting to a purchase. PSI has been in business providing quali ty pumping products and service since 1978, and developed the SolarBee in 1998. With over 250 installations nationwide , t he SolarBee is a "proven performer". Most SolarBees have been installed in wastewater lagoon systems , where the problems of excess nutrients and short detention times are much harder to solve than in fresh water reservoirs. Now, for the past two seasons , the So larBee has been bu ild i ng an impressive record in fresh water reservoirs as well. Our experience indicates that when it comes to water quality issues in large reservoirs , a few thousand dollars spent today can avoid the need to spend millions of dollars tomorrow. If you 're looking for a long-term answer to your water quality problems , please call us for more information and a video tape, and check out our website at solarbee.com . Thank you!

The So/arBee is silent and solar powered. There are no electrical costs or power wires. Coast Guard approved marker lights are available when necessary for boater safety. 6 1. The SolarBee intake hose is up to 36 " in diameter, depending on the model , and the length can be adjusted to treat the top 3 feet to 100 feet of the reservoir. In drinking water reservoirs , the intake should be set slightly lower than the inlet to the treatment plant. 2. In full sunlight, depending on the SolarBee model , up to 10,000 gallons per minute (2,500 gpm of direct flow plus 7 ,500 gpm of induced flow) renews the surface of the reservoir and mixes photosynthetic oxygen throughout the reservoir. The entire reservoir is placed into circulation from sunup to sundown. The larger models treat up to 2,000 acre-feet per machine. The SolarBee has survived high w in ds to 90 mph, high waves , hail , and 36 " of ice without damage. The SolarBee is easy to relocate by moving the mooring blocks . 3. Dissolved oxygen (DO) and pH are increased throughout the treated zone as the reservoir is destratified down to the end of the intake hose. The mixing action and higher pH causes more ammon ia (N) to be stripped from the reservoir, and more phosphorus (P) to be precipitated with calcium hardness to form hydroxyapatite , a stable non-nutrient which settles to the bottom of the reservoir. 4. The SolarBee enables the "good " diatom and green algae to out-compete the "harmful " filamentous or blue-green algae for phosphorus. Phosphorus remains the limiting nutrie nt all season in most cases, instead of nitrogen , thus preventing the blue- green algae from taking over. With fewer or no blue-green algae blooms , there are less actinomycete and other bacterial problems , and consequently there is less production of geosmin and MIB (2-Methyl-i-Borneol). Even a few parts per billion of these chem icals can cause a "musty", "woody" or "lagoon" taste and odor problem in drinking water. 5 . The surface renewal performed by the SolarBee helps control the surface microlayer, which contains extremely concen- trated nutrients . This also helps control blue-green algae growth. More small lapping waves are produced , the water looks "looser" and better, clarity is improved, and gas transfer into and out of the reservoir is improved . 6. By diffusion , even the water lower than the intake hose has higher dissolved oxygen and a higher pH , which keeps more phosphorus (P) tied up with iron and calcium at the silt-to-water interface, and enhances digestion of humic substances. History has demonstrated that being pro-active to halt or reverse eutrophication is much more cost effective than waiting until the problem needs a multi-million dollar solution. The So/arBee is extremely cost effective. So/arBees can be purchased outright, by /ease-purchase, or on a rent-to-own plan. The factory performs the delivery, installation, startup, and on-site training. The SolarBee is constructed of stainless steel metal parts, needs very little maintenance. The SolarBee has a 5 year warranty and an expected 25-year life. ©PUMP SYSTEMS, INC ., 2002 The SolarBee is manufactured by PUMP SYSTEMS , INC., BOX 1940, DICKINSON , ND 58601 FW042502 PHONE 1-800-437-8076, FAX 701-225-0320, www.solarbee .com, www.pumpsystems .com . --~9£ ~cwll@vvBee® Pond Circulators ----------...1 OPERATION AND FEATURES r- "soiutions for pond problems" Description The SolarBee is a floating solar-powered pond circulator.
