I and I Green Grant

The city of New Hope was awarded a grant from the Met Council in spring of 2018 to investigate the potential causes of Inflow and Infiltration, or I and I. 

The city is continuing the Inflow and Infiltration project in the Liberty Park neighborhood this Spring. More information will be present at the May 13 Council Meeting.

Project Information
This study would aim to determine the relationship between storm water and sanitary sewer inflow and infiltration, known as I/I. The study would also aim to target if the majority of I/I is thru publicly owned sewer or privately owned sewer. The study would explore and compare flows in the Northwood North project area. Flow amounts would be monitored on a Mill and Overlay street and a Fully Reconstructed street, to see how a full road section with drain tile and allowing residents to connect sump lines to an underground system compares to just installing a new pavement section. The two study areas can be seen on the image below. Ensign Avenue was fully reconstructed in 2017 while Jordan Circle was milled and overlaid in 2017.

The city of New Hope is currently conducting an Inflow and Infiltration study in your neighborhoodThis study aims to determine the relationship between stormwater and sanitary sewer inflow and infiltration, known as I/I, and learn if the majority of I/I is entering the sanitary system through publicly or privately owned sewer. Sanitary sewer flow is being monitored on Ensign Avenue (a fully reconstructed street) and Jordan Circle (a mill and overlaid street). The results of this study will allow the city to compare the difference in I/I on a street with a full road section and drain tile vs. a street with only a new layer of pavement.


The city of New Hope requests that residents please stop flushing “flushable wipes” down the toilet. These flushable wipes are sticking to the flow monitors the city has in place for the I/I study, and are interfering with the results as well as potentially clogging sewer lines. These wipes are only flushable in the sense that they will go down your toilet. They do not break down in water and as a result snag on roots or deformations in the pipe. This can cause sewer backups in your home, or your neighbors’ homes. Once the “flushable wipes” enter sewer lift stations, they get caught in the pumps and motors and cause expensive issues and additional backups. An image can be seen below of just how these so-called flushable wipes can clog an entire neighborhood’s sewer system.


Please do not flush these “flushable wipes”. They can cause expensive and time consuming problems forFlushable Wipe Issue yourself and for your neighbors.

The city appreciates all of the input from area residents regarding this issue. Thank you for your cooperation and patience throughout this project. Any questions or comments can be directed to the Project Coordinator, Megan Albert at Public Works at 763-592-6765.


We appreciate your cooperation!
