The federal district court found that exclusions j (5), (6) and l barred coverage for damage caused to the city's water main collector system. Sunwestern Contractors, Inc. v. Cincinnati Indem. Co., 2019 U.S. Dist. LEXIS 82642 (D. Ariz. May 15, 2019).
Sunwestern contracted with the city of Tucson for the construction of a water main collector system. During the project, Sunwestern conducted a pressure-test of the pipeline when several flanges, which connected the pipe sections, came apart. The flange failure caused water to tear out gaskets, seriously damage the pipeline, components of the pipeline, and surrounding areas. Four million dollars in damage was caused.
