Waste Water Treatment
Corrigan has reliably served the waste-water treatment industry in St. Louis for more than 100 years. That includes the St. Louis Metropolitan Sewer District (MSD) which has relied on Corrigan for fabrication and installation of process piping systems. All of our work is completed to specifications of the client as well as state and federal regulatory agencies.
Our waste-water treatment team has efficiently completed projects from small piping and equipment replacements to new 200 million-gallon-per-day plant upgrades.
