performance of the equipment, the County would purchase the equipment from them. The Hycor rotary drum thickener was selected to provide uniformity of equipment in the County and to minimize the spare parts budget in the years to come. ANALYSIS The test period has been completed, and the equipment has performed as the County expected. The equipment achieved 100% capacity when it was tested to thicken sludge in the digester. When it was tested directly from the boat clarifier, the machine achieved 80% capacity due to thin sludge and filamentous bacteria in the mixed liquor. The cost for purchasing the Hycor, Thick Tech Basic Unit, Model RDT 150 is $116,460.00. The delivery time of the unit is approximately 12-16 weeks from the time the purchase order is issued. Because the ability exists to shuttle water south, further thought has been given to utilizing this ability to convey waste activated sludge south to the Gifford facility. This is being tried, and if successful may allow a single installation at the Gifford facility, meeting the sludge thickening needs of both North and Gifford. The Utilities Department engineering staff is negotiating with Wharton -Smith, the contractor for the South County Wastewater Treatment Facility Expansion Project, for the installation of this equipment. The result of the negotiations and any associated fees will be presented to the Board for approval in the near future. However, if the staff determined the price to be too high, staff is seeking an approval to bid the work. RECOMMENDATION Utility Services engineering recommends that the Board of County Commissioners approve the following: 1. Direct purchase of the basic unit of sludge thickener equipment now from Hycor in the amount of $116,460.00 due to the 12=16 week lead time. 2. Continue negotiations with Wharton -Smith, Inc. 3. If after negotiations, a favorable installation cost cannot be agreed upon, the staff seeks permission to bid the work. April 7,1998 ON MOTION by Commissioner Grin, SECONDED BY Commissioner Eggert, the Board unanimously approved the 1) direct purchase of the basic unit of sludge thickener equipment now from Hycor in the amount of $116,460 due to the 12-16 week lead time; 2) continuation of negotiations with Wharton - Smith, Inc.; and 3) if, after negotiations, a favorable installation cost cannot be agreed upon, the staff is authorized to bid the work, as recommended in the Memorandum. 52
