Recommended Action
Approve Work Assignment No. 7 with Insituform Technologies, Inc. in the amount of $42,777.06 & Work Assignment No. 8 with Granite Inliner, LLC in the amount of $189,255.00 for the Inflow & Infiltration Project.
Background Information
Inflow and infiltration (I&I) are extraneous flows that enter the wastewater collection system and flow through to the wastewater treatment plant. These flows reduce the capacity of the system and can lead to sanitary sewer overflows. Inflow occurs when storm water enters the sewer system through flooding of the manholes and direct connections of storm water to the wastewater collection system. Infiltration occurs when groundwater and storm water enter into wastewater collection system as a result of physical defects such as cracked pipes, leaking manholes or deteriorated joints. Most of the I&I experienced by the City is a result of infiltration and this I&I Rehabilitation Project is designed to mitigate that infiltration. This I&I Rehabilitation Project includes manhole rehabilitation and manhole lining in the Holiday Park area.
On May 22, 2018, Commission approved the zero-dollar, multiyear Contract Nos. 2018-41.001, 2018-41.002, and 2018-41.003 with Insituform Technologies, LLC., Layne Inliner LLC. (now Granite Inliner LLC), and Hinterland Group, Inc. Commission directed staff to bring each individual work assignment back for Commission approval.
Work Assignment No. 7 is for the rehabilitation of 28 manholes which have been assessed and are in need of structural repair. Work Assignment No. 8 is for the epoxy lining of the 28 manholes being rehabilitated and an additional 56 manholes. The lining will protect the manhole walls from deterioration due to hydrogen sulfide has in the system and extend the life of each manhole. The rehabilitation and/or lining of these manholes will not only extend the life of the manholes but will also reduce infiltration coming from these manholes.
The Contracts have been reviewed by the City Attorney and is approved as to form and correctness.
