Challenge

The 26,000-gallon aeration tank in Kent, Connecticut, exhibited significant deterioration due to constant exposure to aggressive wastewater conditions, including continuous moisture and corrosive chemicals. The rehabilitation project required not only the complete removal of failing coatings and targeted structural repairs, but also meticulous dust containment and environmental controls, as the tank was located adjacent to a school athletic field. Protecting sensitive internal tank components and ensuring compliance with operational and regulatory standards were critical to the project’s success.

Results

The rehabilitation was completed within a three-week window, fully restoring the structural integrity and safety of both the aeration tank and its 20-foot catwalk. Application of OBIC 1000 and OBIC 1150 polyurea coatings delivered long-term corrosion protection and enhanced operational safety. The project achieved environmental compliance and provided a cost-effective alternative to tank replacement, significantly extending the service life of the structure.

About Precision Trenchless

 Precision Trenchless, an OBIC-certified installer, rehabilitated a 26,000-gallon wastewater aeration tank under tight environmental and site constraints. The project included extensive surface preparation, structural enhancements, and the application of a high-performance coating system to ensure long-term durability in a demanding wastewater environment. This trenchless approach delivered reliable protection and performance while minimizing disruption and avoiding costly replacement. 

The Challenge

The municipality in Kent, Connecticut, faced increasing risks from a 26,000-gallon aeration tank suffering from advanced corrosion and chemical attack, threatening structural stability and process integrity. The tank’s proximity to a school athletic field imposed additional requirements for environmental protection and dust containment during rehabilitation. Critical internal tank components needed safeguarding throughout the process, and all activities had to comply with stringent regulatory and operational standards.

The Solution

Precision Trenchless, an OBIC-certified installer, conducted an in-depth assessment and determined that full rehabilitation using OBIC’s advanced polyurea coating systems would address both performance and compliance goals. After evaluating traditional replacement and alternative coatings, the team selected OBIC 1000 and OBIC 1150 for their proven durability and chemical resistance. The project involved comprehensive surface preparation, targeted structural repairs, and precise application of two OBIC coating systems. According to the Project Manager, “Precision Trenchless executed a detailed rehabilitation plan focused on preparation and controlled application, delivering long-term durability and performance in a demanding environment.” This approach ensured minimal disruption and reliable protection for the wastewater infrastructure.

The Results

The project was completed on schedule in just three weeks, restoring the tank’s structural soundness and ensuring the long-term safety of the 20-foot catwalk. The dual OBIC coating systems delivered robust corrosion and chemical resistance, meeting all environmental and regulatory requirements. The solution extended the service life of the aeration tank, provided a cost-effective alternative to full replacement, and minimized downtime. Key metrics included 26,000-gallon tank capacity, three-week project duration, and successful multi-system coating application, underscoring the effectiveness of OBIC technology in challenging wastewater environments.
