Scope

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:

In addition, Michels rehabilitated 141 utility manholes. The majority of the manholes were along a two-lane highway, however some of the work traveled through neighborhoods, and two main sections went through the jungle.

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.

Communication and coordination was key to the success to this project, ultimately leading to the project being completed two months ahead of schedule.
