Resolution to Approve a Professional Services Agreement with Hubbell, Roth & Clark, Inc to Develop an Asset Management Program for the Wastewater Treatment Plant and Sanitary Lift Stations, RFP No. 20-12 ($389,595.00)
Memorandum
Your approval is requested for a Professional Services Agreement with Hubbell, Roth & Clark, Inc. (HRC) in the amount of $389,595.00 for professional engineering services to develop an Asset Management Program (AMP) for the City's Wastewater Treatment Plant (WWTP) and six sanitary sewage lift stations.
The City's WWTP has been operating under a 2007 National Pollutant Discharge Elimination System (NPDES) permit issued by the State of Michigan Department of Environment, Great Lakes and Energy (EGLE) that does not require an AMP. Subsequent NPDES permits issued to other plants have included a requirement for communities to prepare and implement an AMP. A new permit for the Ann Arbor WWTP is pending and will require an AMP. To proactively fulfill this pending requirement, WWTP staff issued RFP #20-12 for professional engineering services to develop an AMP.
The City's WWTP consists of an East and West Plant that were originally constructed at different times. The West Plant reached obsolescence in 2009 and was demolished, replaced and placed back into service in 2015. The East Plant was renovated by the installation of new pumps, blowers, and ancillary treatment components in 2017. Additional capital improvements at the WWTP include the biosolids management equipment, systems and building that were renovated in 2012. All these assets will be part of this AMP.
WWTP staff also operate and maintain eight lift stations at seven locations that raise sewage for gravity flow through the sanitary sewer system to the City's WWTP. Five of the lift stations are in the process of being replaced due to their age and condition. Two stations are scheduled to be replaced in 2020, two stations in 2021 and the last station in 2022.
