No No
BACKGROUND/JUSTIFICATION:
The 2024 Utility budget includes $100,000 within the Rehabilitation and Reconditioning detail of the Sewer Fund for the
East Wastewater Treatment Facility pretreatment channel lining. Deterioration of the concrete channel over the past
two decades from hydrogen sulfide has caused erosion and softened the concrete, impacting structural integrity. Repairs
are necessary for conveyance of influent wastewater through the pretreatment building and its process, including
metering, screening, and grit removal.
Channel lining consists of coating preparations including hydro blasting, hand tooling, patching and descaling surfaces. A
liquid bypass is required for one week to allow for preparations and cure time. Staff will conduct bypass and combo unit
services with the coating team for a project reduction of $21,000. Pipe work will be procured to support this project
separately quoted for $7,113.67. Hiperline has conducted work with us in the past and their product far exceeds
alternatives, important for the environment and conditions this room sustains. Future expansion of this building will not
impact the channel reconditioning, further benefiting best coating recommendation. Staff recommends authorization of
Hiperline quote for high performance lining of the influent channel for $62,780.00.
