Even though Poseidon Hydro Excavation is still a young company — having formed in September 2015 — the company, with just the two founders working for it, has lined up some big jobs. One of the biggest is currently taking place in downtown Milwaukee, Wisconsin, where the hydroexcavation company is working on the Milwaukee Zoo interchange project (interstates 94, 894 and 41 intersect at this location). The company, using its 2016 Ramvac HX12/27, is digging pilot holes for pilings that are running near 96-inch sewer lines. The company has had to dig holes up to 27 feet deep as the Department of Transportation is requiring the pilings to be below the sewer before they can be driven to the required depth. Louis Kelly and Bill Lietzke, owners of Poseidon, say the soil was unstable, which caused cave-ins of the original holes dug and now they are using casings in holes to help complete the job. So far, the company has done 30 holes for pilings ranging from 20 to 27 feet deep and 24 inches in diameter. The project kicked off in February 2016 and there is no end date in sight for Poseidon.
