Waste Water Treatment
Over the past 100 years, Corrigan Company has successfully completed many waste water and water treatment plants in the St. Louis area. We have recently completed 2 major back to back process piping projects for the St. Louis Metropolitan Sewer District (MSD). One was a 200 MGD Plant and the other was a 113 MGD Plant. Both of these projects were completed on time and under budget. MSD has been a long-time customer of ours. They have hired us to fabricate and install process piping in all of their many plants. Repeat Customers make us proud. When you keep coming back, we know we’ve exceeded your expectations…and that’s why we are in this business.
We love what we do and it shows…
