Conotton Creek Diversion

Conotton Creek Diversion

Scope

Michels 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.

Projects

Michels designed, furnished and installed a siphon system to draw down water elevation in a pond impoundment area and maintain upstream river flow during the removal of a high-risk dam. The system consisted of 14 30-inch HDPE siphons, flow-monitoring meters, stainless steel knife gate valves and a priming system.

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.
