Northern Interceptor Sewer Rehab
- Location Guam
- TimelineOctober 2018 - June 2020
Michels utilized ultraviolet light (UV) cured-in-place (CIPP) pipe liners for pipe rehabilitation of 43,984 linear feet of sanitary sewer pipes, making it among the largest UV projects in the United States.
The project’s 130 CIPP installations included:
- 24,358 feet of 30-inch diameter
- 8,380 feet of 36-inch diameter
- 5,986 feet of 42-inch diameter
- 4201 feet of 24-inch diameter
- 1059 feet of 18-inch diameter
Although the terrain was not steep or sloped, crews had to be cautious of the surrounding wildlife. Guam has an enormous population of brown tree snakes, while not poisonous they can make one sick if bitten.
Guam is located in Micronesia in the Western Pacific Ocean and is outside of North America. It is a United States territory located about 9,000 miles away from Michels headquarters. The UV CIPP liner was manufactured in Germany and was shipped directly to Guam in refrigerated sea containers. Demonstrating dedication, the crews lived on the island for nearly the entire length of the project, traveling home about once a month.
The Michels crew in Guam was named Crew of the Year by cured-in-place pipe (CIPP) liner manufacturer, Premier-Pipe USA.
