Mechanical issues temporarily prevented the City's Wastewater Treatment Plant's (WWTP) biosolids dewatering centrifuges from providing the biosolids dewatering capacity required to maintain economical biosolids transport for beneficial use. The Wastewater Division followed the City's Emergency Policy in securing a rental centrifuge from Aspen Rentals to restore the WWTP's required biosolids dewatering capacity.
The cost of the centrifuge rental is estimated at approximately $100,000 for a six-month period if needed, resulting in the need to seek ratification by the City Council via Resolution, in accordance with City of Yakima Administrative Code ADM 3-500 City/County Procurement Manual which requires approval by the City Council for emergency costs exceeding $50,000. The approved Emergency Purchase Order Justification Form and Aspen Rental Agreement are attached for City Council review.
The centrifuge rental is funded through Wastewater Operating Fund 473. |
