Challenge
The Monroe Wastewater Treatment Plant faced the urgent need to rehabilitate its chlorine contact chamber, a critical structure responsible for final water disinfection prior to discharge. The project was complicated by the necessity to keep the plant operational, requiring phased isolation of large basins, careful management of system flows to prevent backups or overflows, adherence to strict time constraints, and the presence of a malfunctioning gate valve causing persistent active leaks. These factors demanded a solution that could be applied rapidly, restore structural integrity, and ensure regulatory compliance without compromising ongoing treatment operations.
Results
The OBIC Armor System enabled the Monroe Wastewater Treatment Plant to complete the rehabilitation of the chlorine contact chamber with just two weeks of total downtime and no operational disruption. The spray-applied polyurea lining provided immediate, long-term corrosion resistance, minimized the risk of overflow, and allowed for a phased, trenchless installation approach. Two crews efficiently executed the work across two phases, demonstrating the system’s effectiveness in maintaining continuous plant operation while delivering durable protection for critical wastewater infrastructure.

The Monroe Wastewater Treatment Plant required urgent rehabilitation of its chlorine contact chamber, a vital component in the facility’s final water disinfection process. The project presented significant challenges, including the necessity to maintain uninterrupted plant operations, the need to phase the isolation of large basins, and the importance of preventing system backups or overflows. Further complicating the effort was a malfunctioning gate valve that resulted in active leaks, all of which had to be addressed within a constrained project timeline. Selecting a solution that could provide rapid application, restore structural integrity, and ensure compliance with environmental regulations was paramount.
The Solution
After assessing the technical requirements and operational constraints, the Monroe Wastewater Treatment Plant selected the OBIC Armor System, applied by OBIC-certified installer CTR Coatings. The decision was driven by the system’s proven performance in municipal wastewater environments, its rapid spray-applied application, and its ability to cure quickly, enabling rapid return to service. OBIC’s advanced polyurea coating technology offered a trenchless approach, minimizing the need for disruptive excavation and allowing phased installation. The expertise of certified crews ensured precise execution and adherence to industry standards, delivering a comprehensive solution for both immediate rehabilitation and long-term protection.
The Results
The rehabilitation was completed efficiently, with only two weeks of total downtime, zero operational disruption, and work executed in two well-coordinated phases by two dedicated crews. The spray-applied OBIC Armor System provided robust, long-term corrosion protection to the chlorine contact chamber, mitigating the risk of future leaks and structural deterioration. The project highlighted the effectiveness of trenchless, phased rehabilitation for critical wastewater infrastructure, yielding cost savings, operational continuity, and extended asset life for the Monroe Wastewater Treatment Plant. Key metrics include: Total Downtime – 2 weeks, Crews Deployed – 2, Phases Completed – 2, Operational Disruption – 0.
