Abstract
The city of Boynton Beach, Florida had 384 feet of 30-inch deteriorated corrugated metal pipe (CMP) in use for under-the-road drainage. Corrosion causes CMP to fail. This corrosion creates voids and causes the road bedding to erode. This Field Report presents an application where the deteriorated culvert was replaced using Snap-Tite.

Introduction
The road leading to the entrance of an apartment complex in Boynton Beach, Florida was in great danger of collapse because of the deteriorated CMP line that ran under it. Major sink holes were evident within the swale of the road.
The Problem
The 30-inch failing culvert was 384 feet long. To dig and replace this culvert would be a major disruption and safety hazard for all residents of the apartment complex.

The Solution Applied
After learning the convenience and ease of a Snap-Tite installation, the city decided against open excavation pipe removal and replacement. Paul Blastic, the Florida Snap-Tite sales representative, helped the city throughout this process. He provided flow rates and recommended the appropriate pipe liner size. Under the direction of storm water superintendent, Louis Johnson, the crew cut a 30-inch opening through the back of the catch basin to insert the new 24-inch Snap-Tite pipe. The pipe was “snapped.”
