Mr. John Bock discussed the circumstances connected with a sewer line back-up at 1280 and 1150 w. Oxford. One owner is not satisfied with the carpet being cleaned, but wants the linoleum and carpet replaced. Stu has requested a legal opinion from the City Attorney. Stu recommended, and the Board concurred, to assist with initial clean-up and evaluate further requests on a case-by-case basis. The Board recommended that staff have a written policy to be distributed as needed. 8. PETITION FROM RESIDENTS NEAR 777 W. OXFORD RE: W. NASSAU WAY. The Board received a petition from citizens near 777 W. Oxford Ave. regarding a piece of property currently for sale on W. Nassau Way. They are concerned that if the lot is divided and sold, multiple units with be constructed and a permanent driving exit onto W. Nassau Way will create additional hazards. Community Development was given a copy of the petition, and responded that most likely the lot could only be divided for one single family home. 10. REVOCATION OF WATER AND SEWER TAPS. In a prior meeting, the Board received a request from an industry in the City of Sheridan for a water tap. The Board received a copy of a legal opinion from the City Attorney regarding revocation of water and sewer taps, based on a request for a water tap from a property inside the City of Sheridan. The City Attorney, in his memo, did not recommend such an arrangement. Ms. Habenicht moved; Mr. Wiggins seconded: Ayes: Nays: Members absent: Motion carried. 11. INFORMATIONAL ITEMS.

Olsen, Secretary [S E A L] -6- A TT. 3 InterOffice Memo To: Doug Clark, City Manager From: Frank Gryglewicz, Director of Finan · Date: November 27, 1996 Subject: Financing Warer System Improvements This is an update on efforts to provide least-cost financing for the improvement to the water system. Since the bond issue failed in November, Stu, Jeanne, and I have begun examining the following alternatives to obtain the necessary funds for the water system improvements. 1. Use Colorado Water Resources and Power Development Authority revolving funds. This option will allow a 20 percent federal government subsidy on the interest. 2. If revolving funds are not available, we will look at short-term financing and another election in November, 1997. An aggressive campaign to sell this issue would be undertaken as early as possible. 3. If the election fails we will either look at revolving funds again or a revenue bond issue. I will keep you informed of the progress of this project. If you have questions, comments, or concerns please call.

I AT T. Lf are being negotiated by city staff and Brown & Caldwell. the design engineer, for inclusion in the Pbase lb project: Trickling Filter Media Dewatered Sludge Pumps Engine Generators None of this equipment will be purchased directly by the cities. Purchase requirements are included in the Phase Ib construction bid package and the equipment will be and supplied by the successful contractor. Approval of the equipment will be made with the approval of the construction contract, currently scheduled to come before city council on January 6, 1997 at a regularly scheduled council meeting . Bids for the project will be received on December 12 and the qualified, complete low bidwill be presented to Council for approval on January 6, 1997. Irick!inr Filtet Media Trickling filter media is used in two treatment processes: 1) organic removal (secondary treatment) and 2) ammonia removal (nitrification). In both of these processes, micro-organisms grow on the surface of the media . Wastewater is poured over the media to come in contact with the micro- organisms, which then remove either the organic matter or the ammonia. The specially designed media consists of plastic sheets that are glued together to provide the wastewater/organism contact as well as mixing of the wastewater in the filters. There were three media suppliers when the first filters were built in the Phase Ia project (1991). Since that time, two of the suppliers have eone out of business, including the supplier of the media in the Ia project . The remaining supplier. BrentWood, Inc ., manufacrures a high quality filter media. Brown & Caldwell and staff have negotiated a total price for the media which will be included in the construction contract. The pre-negotiated price compares favorably with the costs for recent similar projects. The total cost of the media will be $1,070,000. The only other option to a pre-negotiated price was to let the bidding contractors do pricing on their own and put the price in the contract. This approach, with a single supplier of the media, would probably resulted in a higher project cost . DEC -9-96 MON 12:38 PM L/E WWTP FAX NO. 3037622620 P. 2 Dewateresi Slnd&c Pwnps Moving dewatered sludge from the centrifuges to the loading facility will be accomplished by pumping. Two pumping options were identified during project design: 1) piston pumps (commonly u~ to pump concrete) designed for sludge service, and 2) progressive cavity pumps, specifically designed for slud2e service. The piston pumps can pump solids up to 40% dry weight and would handle the dewatered sludge at 20% quite easily. The cost of each pump is approximately $156,000.00 and three pumps (or two pumps with additional alternate equipment) are required. Progressive cavity pumps can handle dewatered solids, but at concentrations below what a piston pump can handle. Above 15% solids, special fearures are needed to reliably operate and to minimize maintenance costs. One progressive cavity pump was identified as having the needed features and was tested at the facility for several weeks. The test unit operated successfully, at concentrations well above 20%. The cost of the pumps was negotiated with the supplier and is included in the bidding documents . Seepex is the pump manufacturer . The cost of each pump is $36 ,090.00 (total of $108,270.00 for 3 pumps), well below the cost of the piston pumps. In the event the progressive cavity pumps do not meet specific operating and maintenance criteria, the pumps will be returned to the manufacrurcr and piston pumps will be insT.alled. The dewatering facility is designed to accommodate either type of pump. Engine Generators The existing cogeneration system is presently at the end of its useful life and is being replaced in the Phase lb project. The new system will utilize all of the digester gas produced at the plant, compared to about 30% utilization now . The new system will use electricity generated in the plant directly , which will eliminate the cost differential between current sales to Public Service Company and electricity purchase cost from PSC (we currently receive less per kW-hr than we pay .) The new system will also be an emergency power system, fueled by narural gas, to provide partial power during a PSC electrical outage. To accomplish this, the engine/generator sets must be able to run reliably on both natural gas (a clean high BTU fuel) and digester gas (a sour low BTU fuel.) Jenbacher, an Austrian company, has the most advanced and reliable carburation system to allow operating in a dual fuel mode . Changes in the operating parameters of the engine are made by computer and sophisticated electronics . They have several installations of the same type. including in the United States . The efficiency of their equipment is also higher than other manufacturers, with low emissions of NOx. Brown & Caldwell and staff have negotiated a purchase price of $880,000 for two engine/generator sets for the project. This cost is well below the original equipment estimate. Another option being considered for the use of digester gas is its direct sale to PSC . The gas would be piped to the Arapahoe power plant, located on the other side of the river , and burned in the plant.
