River Road Outfall Repair

The Missouri River flooding of 2011 and 2014 caused many inland pipes to backfill cause damage inside the 96” pipes. This flooding also caused many safety hazards that needed to be addressed, which created the need to build a new outfall structure and isolation vaults to ease the flow of rising river levels during times of heavy rain.  

 

Hawkins performed the replacement of the 96” diameter pipes that were damaged in the floods and constructed a new double 96" outfall structure and isolation vaults to prevent water from backfilling the pipe line when the Missouri River is at elevated levels. This outfall structure is boasts the largest duckbill check valves in the Midwest on the dual 96” outfall pipes.

 

Hawkins also performed other pipe line repairs for 84" diameter reinforced concrete pipe that had failed during the flood of 2011. The project took roughly six months to complete, requiring extensive dewatering and sheet piling operations due to elevated water levels along the shores of the river.
