Conotton Creek Diversion

Conotton Creek Diversion

Scope

Michels Construction, Inc. designed, installed and operated a system to divert peak flows of up to 168,000 gallons per minute, or 242 million gallons per day, so a pipeline could be open cut in dry conditions. The Michels team calculated the need for a total of nine 16-inch and 18-inch electric submersible pumps. Nine parallel 24-inch HDPE pipe runs were fusion welded to 600-foot lengths, including two 45-degree bends and three 90-degree bends on each pipe run. More than a mile of pipe was assembled and put into operation within seven days, allowing the project to stay on schedule. Michels also installed 42 deep wells and 6,000 lineal feet of wellpoint dewatering systems to lower and control groundwater levels throughout the project to further enhance working conditions.

  • Michels Dewatering group was tasked to design, install and operate a system to divert peak flows of up to 168,000 gallons per minute, or 242 million gallons per day, so that a pipeline could be open cut in dry conditions across the Conotton Creek.

Projects

Michels developed a diversion plan for Hay Creek to allow a pipeline crew to perform an anomaly dig to repair an imperfection of a high-pressure pipeline that crossed the creek.

Michels constructed an underground water retention cistern inside of an occupied apartment  building. Due to historic water levels in Milwaukee, WI, a parking garage had been underwater and inaccessible since March of 2019.

Michels designed a water diversion solution for the Little Calumet River for an anomaly dig. The river serves as a drainage canal for the area and can rise at least 4 inches in water elevation. As little as 1 inch of rain can substantially alter the flow of the river.

Michels performed casing removal on sections of natural gas pipe in Minnesota, Wisconsin and Kansas. The work sites in Minnesota and Wisconsin were wetlands, while the sites in Kansas were located in agricultural fields.
