HomeMy WebLinkAboutPR 22332: SLUDGE PROCESSING AT THE WASTEWATER TREATMENT PLANTS City of t rthu Texas INTEROFFICE MEMORANDUM Date: January 20, 2022 To: The Honorable Mayor and City Council Through: Ronald Burton, City Manager From: Calvin Matthews, P.E., Water Utilities Director RE: PR 22332—Sludge Processing at the Wastewater Treatment Plants Introduction: The Wastewater Treatment Plants (WWTPs) have had ongoing issues with their dewatering centrifuges' operational capabilities.The centrifuges are used to dewater excess biological solids (sludge) which build up within the WWTP as part of the biological treatment process. With the centrifuges offline at the Port Acres WWTP, due to delays in obtaining repair parts, the solids built up in the plant to the level the plant was facing potential sludge overflow. This could cause the plant to exceed its permitted discharge limit. To prevent this, the excess or waste solids had to be removed from the process. The removal of the solids required an alternative method of dewatering to allow disposal at the City's landfill. Due to the importance of excess sludge removal from activated sludge WWTPs and the lack of standby centrifuges at the City's WWTPs,bids were received by the Water Utilities Department for emergency waste sludge dewatering and hauling. Sprint Waste Services was the lowest,most responsible bidder and was contracted to process sludge with a mobile belt press and haul it to the City's landfill. Due to repair delays to the centrifuges at the City's WWTPs and the inability to operate the plant without this required service, the original contract sum of $80,000 was exceeded and needs to be increased by $10,777.76 to $90,777.76. This funding will cover the existing amount owed to Sprint Waste.This amount is within the allowable 25%limit of contract increases.After this payment,the contract will be terminated and a new contract will be bid.The requested total projected budgetary amount of this proposed resolution is budgeted for in Account No. 410-40-225-5470-00-00-000, Other Contractual Services.
