Northern Interceptor Sewer UV CIPP

Michels Trenchless, Inc. used ultraviolet light (UV) cured-in-place pipe (CIPP) liners to rehabilitate nearly 45,000 linear feet of sanitary sewer pipes and 141 utility holes in Guam, making it among the largest UV projects in the United States. The 130 installations included 24,358 feet of 30-inch, 8,380 feet of 36-inch, 5,986 feet of 42-inch, 4,201 feet of 24-inch, and 1,059 feet of 18-inch diameter pipe.

Communication and coordination was key to success, ultimately resulting in project completion two months ahead of schedule. Guam is nearly 9,000 miles away and 15 hours ahead of the Michels home office in Brownsville, WI. Shipping the required equipment and materials proved difficult with customs. Michels shipped 10 pieces of equipment including spare parts and tools. The UV CIPP liner was manufactured in Germany and was shipped directly to Guam in refrigerated sea containers.
