To dig or not to dig? Trenchless technologies like ultraviolet (UV) curing point to a future for rehabilitating underground pipes without digging.
Communities of all sizes now have an additional tool to rehabilitate water and sewer pipes without digging them up. It’s ultra violet (UV) cured-in-place piping (CIPP), and some industry experts see it as the future of trenchless technology. One community in the Twin Cities metropolitan used the new technique to rehabilitate utilities with minimal disruption to property owners. This first UV curing application in Minnesota was completed at Medicine Lake in Plymouth on sewage piping.
Why did Medicine Lake choose to use UV curing?
The City’s sewer main had reached its life expectancy and needed rehabilitation. The community is located on a narrow 210-acre peninsula on a lake, so a less invasive approach seemed attractive. Traditional curing, which uses steam and hot water, comes with disadvantes such as requiring an extensive footprint, a long time to perform and heavy equipment. When the City turned to UV curing, they were able to avoid digging up residents’ pristine shorelines and dramatically reduced the impact that heavy equipment would have made.

Top 10 Reasons to Use Ultra Violet Cure
UV curing is the future of trenchless technology due to its efficiency and environmentally friendly techniques and applications. Towns and cities of any size could benefit from UV curing -- especially if the project area is adjacent to water or is in a confined area.
