FROM: Kurt Muth, PE, Assistant Director of Public Works, Assistant City Engineer
DATE: September 8, 2026
SUBJECT:
A resolution authorizing the Director of Purchasing to Process a Change Order to the Agreement with Insituform Technologies, USA LLC for the 2026 Sanitary Sewer CIPP Lining Contract in the amount of $85,000
PURPOSE:
To increase the Contract amount from the original value of $1,344,479.50 to a new Contract value of $1,429,479.50 due to adding additional sewer segments to be lined.
BACKGROUND:
This change order is necessary to increase the contract value to address additional sanitary and storm sewer segments that were brought to the City’s attention after the original scope of work was established. These segments have been identified as candidates for lining to help address infiltration and inflow (I/I) issues within the sewer system. Lining these additional segments will help reduce the potential for groundwater and stormwater entering the sanitary sewer system, improve system capacity and performance, and support the City’s ongoing efforts to reduce I/I and associated impacts on the wastewater collection system.
DISCUSSION:
The project was originally bid on February 25, 2026, with Insituform Technologies, USA LLC providing the low bid. The contract was then presented and approved at City Council on April 14, 2026, as resolution R26-083. Additional funds are proposed to come from account 510-4063-511-7314 (IB018 Sanitary Sewer Evaluation & Rehabilitation) which has a budget of $3,750,000 for 2026.
IMPACT STATEMENT:
Adopting this resolution will improve system capacity and performance and support the City’s ongoing efforts to reduce I/I and associated impacts on the wastewater collection system.
RECOMMENDATIONS:
I request the proposed resolution be adopted.
