Rathbun Regional Water Association – Intake Structure

Centerville, Iowa

This project’s scope required the design of an intake structure for water treatment from Lake Rathbun at a depth of 53 feet below ground level.

Stiver Engineering provided the client with structural design through a 20-foot diameter by 64-foot deep caisson design. We designed the reinforced concrete structure to be poured in lifts and sunk into the earth until the cutting edge of the caisson reached the design elevation, and it was installed on the bank of Rathbun Lake, Centerville, Iowa. Stiver Engineering provided structural plans to the client for construction.
