City of Gladstone Infiltration and Inflow Project

The City of Gladstone has a longstanding history of Oregon Department Environmental Quality (DEQ) violations pertaining to raw sewage overflowing into the Clackamas River.  Violations that have been a result of stormwater Infiltration and Inflow (I&I) into the city’s sewer collection system.

 As part of a Mutual Agreement Order (No. WQ/M-NWR-2019-038) between DEQ and the City of Gladstone; DEQ granted the city time to correct our system deficiencies. To date the City has met all obligations with DEQ.

In May 2019 the City contracted with Leeway Engineering to complete field work which included smoke testing and CCTV investigations, the findings from the field work was used to prepare the final I&I report for DEQ.

In April 2022 the City Council approved a contract with Leeway Engineering to design the I&I Reduction Project. Leeway Engineering is in the final design stages of the work that needs to be completed by January of 2024.

The City of Gladstone recently requested an extension to the deadline for the I/I project, DEQ has granted this extension.  The City issue a second Request for Proposal in November 2023 and will bring a contract before City Council in early 2024 for approval.
