OF BALTIMORE, MARYLAND, IN THE AMOUNT OF $226,320 FOR A REVISED TOTAL OF $537,640 ISSUE:
Approval of a First Amendment to Services Agreement for Temporary Press Rental and Dewatering Services with SYNAGRO-WWT, INC., of Baltimore, Maryland, in the amount of $226,320 for a revised total contract amount of $537,640.
RECOMMENDATIONS:
That the City Council:
Approve the First Amendment to Services Agreement for Temporary Press Rental and Dewatering Services with SYNAGRO-WWT, INC., of Baltimore, Maryland, in the amount of $226,320 for a revised total contract amount of $537,640; and Authorize the City Manager, or designee, to execute the First Amendment to the Services Agreement, including making minor and non-substantive changes.
BACKGROUND:
The City of Riverside Public Works Department, Wastewater Division, is responsible for the collection, conveyance, and treatment of wastewater for over 93,000 customers within City limits. The facilities consist of over 800 miles of gravity sewers, 400 miles of City laterals, 20 wastewater lift stations, 16,000 sewer manholes, and the Riverside Regional Water Quality Control Plant (RWQCP) which has the capacity to treat 46 million gallons per day. Additionally, under agreements with the City, the RWQCP provides wastewater treatment for the Edgemont, Jurupa, and Rubidoux Community Services Districts, and the unincorporated community of Highgrove. To satisfy the United States Environmental Protection Agency’s (EPA) National Pollution Discharge Elimination System (NPDES) permit, wastewater must be treated to achieve regulatory water quality standards. The RWQCP treatment processes requires biosolids to be dewatered and dried and hauled off site for beneficial reuse.
On July 23, 2022, RWQCP experienced catastrophic failure of the Centrysis centrifuge, a key piece of equipment used to dewater sludge, the residual material produced as a by-product during sewage treatment. The failure left the RWQCP unable to process the required 170 gallons per minute of sludge necessary to maintain continual operation. Consequently, RWQCP was required to retain unprocessed sludge onsite.
Retaining sludge onsite can have long- and short-term impacts. Short-term impacts include increased odors and higher solids concentrations throughout the treatment process. Long-term impacts are an increase in biological oxygen demand (reduced treatment effectiveness) and permit exceedances. Whereas reduced treatment effectiveness can potentially be detrimental to public health, permit violations can expose the City to regulatory liability and penalties.
To eliminate the potential for long-term impacts, staff requested City Council approve an emergency purchase order and contract documents, to continue to comply with federal, state, regional, and local regulatory requirements as part of the wastewater treatment process.
On October 4, 2022, the City Council approved an emergency purchase order and ratified the Temporary Press Rental and Dewatering services agreement (Agreement) through December 31, 2022, with SYNAGRO-WWT, INC. of Baltimore, Maryland in the amount of $311,320 - an urgent necessity to protect the public health, welfare, safety, and property in accordance with the Purchasing Resolution No. 23914 Section 301(c).
DISCUSSION:
Due to unforeseen delays with the repair and installation of the Centrysis centrifuge, SYNAGRO-WWT, INC. was asked to affirm the applicability of the originally quoted daily rates to an additional 20 days of rental and hauling services within the original term of Agreement. In support of the extended services and SYNAGRO-WWT, INC. maintaining the original daily services rate, staff is requesting the City Council ratify the First Amendment to the Agreement in the amount of $226,320 for a total contract amount of $537,640.
Purchasing Resolution No. 23914, Section 301 (c) states, “An ‘emergency’ shall be deemed to exist under any one or more of the following circumstances…(c) A breakdown in machinery, facilities, or essential services which requires the immediate Procurement of Goods, Services or Construction to protect the public health, welfare, safety, or property, or personal/confidential information”. The continued breakdown in machinery and essential services require a change order to the original urgent purchase order.
The Purchasing Manager concurs that the action to approve is in compliance with Purchasing Resolution No. 23914.

These items support Strategic Priority 4 – Environmental Stewardship and Goal 4.2 – Sustainably manage local water resources to maximize reliability and advanced water reuse to ensure safe, reliable, and affordable water to our community.
