The general contractor had previous knowledge that there was a 12” high-pressure water main in close proximity to where they intended to auger and install the monitoring well. The contractor met with the drilling company and informed them of the existence of the 12” water main. The contractor then called the underground utility locating agency also known as One Call System. Shortly after the request to locate and mark out the existing underground utilities, the city-owned and operated water company marked out its underground line(s). However, the 12” high-pressure water main was not marked. The contractor directed the drilling company it hired to drill, despite its knowledge there was an existing 12” high-pressure water main in close proximity to the drilling location that was not marked/located. The drilling company, despite the knowledge the water main existed and was not marked, complied and began drilling. Low and behold, twenty minutes after the drilling began they drilled directly through the high-pressure water main. The geyser reached more than twenty feet high, and the water flow was so forceful and voluminous it flooded the warehouse causing massive damage to both the building and its contents.
