Request for Qualifications:
Sewer Inflow and Infiltration Planning and Design

Qualifications Due: 5/25/2023 @ 2:00 pm PDT

RFQ Document: Request for Qualifications - Sewer Inflow and Infiltration

Description: The 2021 Sewer Utility Capital Improvement Program Update indicated that the City needs a wastewater rehabilitation program to reduce the amount of I&I that enters the collection system. The CIP has broken up the I&I program into two separate projects: program planning (long term/annual) and construction (short term):

  • CP-1: Infiltration and Inflow Program: On-going Citywide program to identify Infiltration and Inflow issues throughout the City’s collection system (monitoring, inspection, etc.)
  • CS-1: Infiltration and Inflow Repair: Address found I&I issues (CIPP, injection grouting, pipe replacement, lid replacement, etc.)

Most I&I issues are assumed to be in the Old Town area of the City where the sewer main piping is aged concrete bell and spigot. City Council approved the 2023/2024 budget with $615,000 to build our I&I program and complete the initial annual maintenance. In early 2023, the City began monitoring flow at four locations throughout Old Town in preparation for this I&I program. Data collection began on March 1 and is expected to be collected through July/August 2023.

Using this data collection set, the consultant will create a maintenance program to reduce I&I into our system. Additionally, the selected consultant will design a construction plan set for the 2024 maintenance program based on the consultant’s highest priority findings.
