AGENDA ITEM
AGENDA MATTER:
GRIT CHAMBER REHABILITATION PROJECT
EXECUTIVE SUMMARY:
Staff seeks the City Council's approval to enter into an agreement with National Coating in an amount of $77,320.
DISCUSSION:
The influent grit channel/grit chamber was constructed in 1997, and with receiving an average flow of 2.2 MGD, high concentrations of hydrogen sulfide is present. Micro biologically induced corrosion in sewer environments occurs when hydrogen sulfide gas is metabolized by microbes into sulfuric acid. This sulfuric acid attacks concrete compromising the integrity of the structure.
FISCAL IMPACT:
Use $77,320 form 605 Wastewater Reclamation account 605.605.601.08.837 (Equipment Budget) for FY24
RECOMMENDED ACTION:
Staff recommends that the City Council take the following actions:
1. Approve the Grit Chamber Rehabilitation with National Coating for repairing deteriorated concrete and applying the protective coating of Sherwin Williams poly coat 115.
2.Authorize the City Manager or designee the authority to sign an agreement.
