INTEROFFICE MEMORANDUM

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.
