Phalen Creek Storm Tunnel Rehab
Portions of the Phalen Creek Storm Tunnel system are in need of rehabilitation. The rehab work is to be completed in 3 project phases (2016 – 2019).
The main work site is located between 4th Street and the Kellogg (3rd) Street Bridge, and is planned to be utilized through the Spring of 2019.
The rehab work is mostly underground, and includes constructing a reinforced concrete liner inside the existing tunnel, as the existing tunnel floor and roof are in poor condition.
Phase 1 project work began in the Fall of 2016, and included construction of a temporary paved trail to maintain pedestrian and bike traffic around the work site.
The temporary trail and chain-link fencing (to secure the work site) are to remain in-place through the Spring of 2019. Phase 1 work was completed in October of 2017.
Phase 2 project work is planned to begin in November of 2017 and be completed in the Spring of 2018.
Phase 3 project work is planned to begin in the Fall of 2018 and be completed in the Spring of 2019.
Westside Inflow and Infiltration Project
In 2018, the City of Saint Paul received a grant from the Metropolitan Council to complete an Inflow and Infiltration (I&I) Demonstration Project. This is a multi-year project that will inspect and potentially repair the sanitary sewer system in a designated area located on Saint Paul’s Westside neighborhood, see map for details.
If your property is within this area, you should have received a letter about this project, including receiving a FREE inspection of your sanitary sewer. To receive this free sewer inspection, property owners must contact the city’s contractor, SEH at 651-318-0350 as soon as possible to set up an appointment before June.
This sewer project has two phases:
- 2019 (Inspection Phase): Inspect sanitary sewer service from homes by free televised scoping and conduct area-wide sewer flow monitoring.
- 2020 (Repair Phase): Review sewer service conditions, evaluate repair options, and potentially make needed repairs with minimal or no cost to property owners.

West Side Flats Flow Monitoring Program
This study project will address the inflow/infiltration (I/I) mitigation efforts in the sanitary sewer collection system serving the Riverview Lift Station area on the City of Saint Paul west side area. It is to determine if adequate I/I reduction has occurred from recent sanitary sewer collection system investigations and sewer rehabilitation to allow continued community development in the West Side Flats area.
The overall scope of the flow monitoring program will be conducted from early fall 2018 through fall 2019 (the remaining duration of the current West Side Flats Flow Monitoring Program).
Como / Zoo Flow Monitoring and Capacity Analysis Project
The program is designed to gain a better understanding of the wastewater flow conditions in the sanitary sewer collection system downstream of the Como Zoo.
The Como Area neighborhood is located east of the Como Avenue and Lexington Parkway N intersection in the City of Saint Paul. This neighborhood is located downstream of the Como Zoo, which consists of open air animal exhibits that require the storm water runoff to be discharged to the sanitary sewer.
The objective of this work plan will be to collect additional wastewater flow data to update and calibrate the City’s existing sanitary sewer model (PCSWMM) as needed to determine any future measures required to minimize sanitary sewer backups in the Como Area neighborhood. SEH will work with City staff to coordinate current and future efforts in developing an effective flow monitoring plan which will include the installation and data collection of wastewater flows at approximately six (6) meter locations and a rain gage station for the Como Area neighborhood of the City of Saint Paul.
The overall scope of the flow monitoring program will be conducted from early fall 2018 through fall 2019.
