Installer Spotlight: A Tale of Two Clarifiers for Midwest Infrastructure Coatings

Midwest Infrastructure Coatings (MIC) has been busy working across Missouri, using OBIC products to restore and protect wastewater clarifiers.  In the towns of Hannibal and Nixa, two critical clarifier projects have been completed, each with its unique challenges but with the same goal – ensuring the long-term integrity of wastewater infrastructure.

Hannibal, Missouri – A Clarifier Reborn

In Hannibal, a 7,000 square-foot clarifier that had been in service for over 30 years was facing severe corrosion due to hydrogen sulfide (H2S) gas.  The concrete had deteriorated so much that the rocks within the launder were exposed.  The team at MIC got to work restoring the structure with the OBIC Armor Multi-Layer System.

The project kicked off with a subcontractor sandblasting the surface, followed by the application of OBIC 1000 polyurea to the clarifier walls and the launder section at 100 mils thick.  The crew used OBIC 1306 structural foam to successfully fill a gap in a damaged area by the launder.  Despite the unpredictable weather, which could have forced the team to put the clarifier back into service prematurely, the fast-set OBIC products allowed them to complete the project efficiently and on time.

The city of Hannibal was impressed with the speed of the application and the immediate results, extending the life of the clarifier for decades to come.  What was once a major liability for the municipality has now become one of its most reliable assets.

Nixa, Missouri – A Record-Breaking Project

In Nixa, Midwest Infrastructure Coatings tackled the largest exterior clarifier ever coated in OBIC’s history – spanning 16,700 square feet.  This 20-year-old structure was in need of rehabilitation to extend its life before any significant issues arose.  The project began with sandblasting and painting the steel rotation assembly, a task that took four weeks for the subcontractor to complete due to challenging weather conditions.

Once the surface was prepared, the MIC team worked tirelessly over 12 days to complete the OBIC coating process.  They applied OBIC 1000 polyurea at 100 mils thick on the clarifier’s floor and launder, followed by OBIC Armor in gray for the walls. The city of Nixa, one of MIC’s largest clients, has a proactive approach to infrastructure management – requiring any new wastewater structures, such as manholes and lift stations, to be lined with OBIC products before acceptance into the city’s system.

The OBIC Difference

Both the Hannibal and Nixa projects demonstrate the value of OBIC’s advanced lining systems.  By using OBIC Armor, Midwest Infrastructure Coatings was able to extend the life of these critical wastewater clarifiers, saving municipalities the cost of major repairs or replacements down the line.  With the help of OBIC, these structures are now set to provide reliable service for many years to come.
