N CITY OF ms FAYETTEVILLE ARKANSAS MEETING OF AUGUST 6, 2019 TO: Mayor and City Council THRU: Don Marr, Chief of Staff Water & Sewer Committee Tim Nyander, Utilities Director FROM: Greg Weeks, Wastewater Treatment DATE: July 17, 2019 CITY COUNCIL MEMO SUBJECT: Repair of Cyclo -Blowers at the West Side Treatment Facility RECOMMENDATION: Staff recommends the repair of two (2) Gardner Denver brand cyclo -blowers for the West Side Treatment Facility by Blocker & Wallace Service LLC in the amount of $31,550.00 plus applicable taxes, and approval of a budget adjustment. BACKGROUND: The West Side Treatment Facility utilizes a biological nutrient removal process to treat an average of 7.2 million gallons of wastewater per day (2017, Annual AVG). Microorganisms, or `activated sludge' feed off both organic and inorganic pollutants in the wastewater. As the microorganisms feed and multiply, a portion of the process solids or sludge must be removed to maintain a proper balance between microorganism populations and available food. The removed solids or Waste Activated Sludge (WAS) are partially dewatered before being sent to the Biosolids Management Site (BMS) for further treatment and later sold as a Class -A Biosolid fertilizer. Before WAS is dewatered or sent to the BMS, it is temporarily stored in one of two tanks. During its storage time, mechanical cyclo -blowers mix and aerate the WAS mixture to prevent solids settling and the microorganisms from dying. Five cyclo -blowers are available to mix the contents of the WAS storage tanks; recently vibration analysis results indicated that two of the cyclo - blowers had hidden, internal points -of -failure requiring disassembly inspection and repair evaluation by a certified repair facility. DISCUSSION: Earlier this year, a cyclo -blower unit experienced an `Alarm' Condition Level during vibration analysis and was shipped to Blocker & Wallace Service LLC — a Gardner Denver factory authorized repair vendor — for disassembly, inspection and repair proposal. The unit's `Alarm' Condition Level was determined to be from Head Plate bore damage, caused by an internal bearing failure, and damage to the rotary shaft from failed internal and external lip seals. The damaged bore will require re -sleeving and machining repairs while the damaged rotary shaft will Mailing Address: 113 W. Mountain Street www.fayetteville-ar.gov Fayetteville, AR 72701 require re -sleeving and new lip seals. This unit was quoted for repair by Blocker & Wallace in the amount of $15,725.00. A second unit that was sent to Blocker & Wallace for disassembly and inspection has experienced similar lip seal failures and needs to be repaired in the amount of $15,225.00. Considering that purchase prices for remanufactured or new blowers range from $24,000 to $33,500, staff recommends completion of the recommended repairs for the two cyclo -blower units in the amount of $30,950.00 plus estimated freight in the amount of $600.00. Taxes are estimated in the amount of $3,076.13 for a total of 34,626.13. Because it was necessary to have the repair facility disassemble the units to determine the extent of hidden and unknown damage to equipment already purchased, a bid waiver and/or formal sealed bidding is not necessary according to Ark. Code Ann. §19-11-203(14)(DD). BUDGET/STAFF IMPACT: Budgeted funds will be moved from the Sanitary Sewer Rehabilitation account to the Plant Pumps and Equipment account to cover the repair costs for the cyclo -blowers for the Westside WWTP. Funds being moved are budgeted funds for sewer rehabilitation/replacement and maintenance.
