Klein and Hoffman - Structural and Restoration Engineers

The SEPA project was created to improve the water quality of the Calumet Sag Channel through the use of several newly constructed pumping stations and waterfall structures designed to return oxygenated water to the channel.  The total pumping capacity of all five stations is 1.3 billion gallons per day.  The station sites comprise a “water park” setting open to the general public, and include landscaped grounds and walks for viewing and enjoying the waterfalls.
