West Fargo, ND
For five years now the City of West Fargo has used the I&I Barrier to stop unwanted water coming into the manholes. Excessive ground water filtering into the sanitary manholes has been a problem in the West Fargo area due to massive flooding in the spring and high ground water tables. The I&I Barrier has stopped this water from infiltrating into the sanitary manholes keeping it in the soil where it belongs. We have found several advantages to the I&I Barrier like:
• Easy Installation, no learning curve
• Stops water and sediment infiltration through the adjusting rings
• Helps keep manholes clean during construction
• Keeps mortar from falling into manholes
• Easy to inspect
• Easily adjusted for different road variations.
Bottom line: It saves contractors, engineers and Cities time and money!!
We are happy with the I&I Barrier and will continue to use it for years to come.

As a City Engineer in West St. Paul, Minnesota, and prior to that as an Assistant City Engineer in Chanhassen, Minnesota, I have specified the I&I Barrier for a combined five years. I have found that the I&I Barrier accomplishes what I want it to and more.
The I&I Barrier not only keeps water out of my sewer system, but I have found that it keeps mortar from falling down into the bottom of my manholes when installing rings, keeps sediment out and lastly the I&I Barrier makes my manholes that much more presentable with its visible safety yellow color.
I am more than happy with the I&I Barrier. The cost savings are considerable. I would recommend the I&I Barrier to any city that is addressing the issue of I/I in their sewer systems.
