An I & I study was completed in 2022 covering the areas south of Allen Blvd to SW Hart Rd and from SW Hyland Way to SW Hall Blvd. The study area was divided into 6 sub-basins according to monitor flow at these locations. The sub-basins were then ranked according to the percentage of rainfall infiltrating into the city sanitary sewer system. The sub-basin determined to have the highest I & I was selected as the top priority which is the neighborhood along SW 131st Ave between SW Barlow Rd to SW Hanson Rd.

There are sanitary sewer mainlines and laterals that are allowing groundwater to infiltrate into the sewer system. The goal of this project is to reduce flows from inflow and/or infiltration by repairing or replacing public sanitary sewer mainlines and manholes and additionally private sanitary laterals and side sewers.
