One of the most dramatic moments for Waterbury’s aging drinking water system came when water from a pipe break was so forceful that it launched large rocks into the air, damaging a garage a hundred feet away when they came down.
Other frequent near-tragic events led to the fast-tracking of an improvement program. In September 2025, a break in a transmission line cut water along a 10-mile stretch of pipe to nearly half of the city, causing 24 schools to close, flooding homes and businesses, and triggering a boil-water order. The city of Waterbury Water Department had to use a payloader’s bucket to flatten this geyser.

TESTIMONIALS
"The City of Fort Lauderdale was dealing with aging infrastructure that due to erosion from the brackish saltwater was virtually disintegrating. We knew that we needed to provide the quickest solution possible for our community, and the technology utilized allowed for the replacement of the compromised FM in record time. This trenchless process, coupled with the use of HDPE and its 100 plus year life span, is quite simply the best available technology out there."
Omar Castellon, P.E. Assistant Public Works Director – Engineering, City of Fort Lauderdale
