The Village of Hamler, Ohio, faced a significant challenge with its wastewater management system. Due to severe hydrogen sulfide (H2S) corrosion and excessive groundwater infiltration, the town was dealing with extreme water intrusion into its manholes during rain events. This increased water volume was straining the lagoon system, forcing it to process more water than it should and not being able to retain it for the required amount of time, creating potential compliance issues with the EPA.
To combat these issues, Hamler turned to Advanced Rehabilitation Technology (ART) for a solution. ART utilized OBIC’s high-performance leak stop and lining solutions and the results were immediate and impressive.

Project Scope and Execution
In 2022-2023, Hamler initiated a rehabilitation project targeting 25 of its 100 manholes. The process was carried out in increments of about 10 manholes at a time, allowing the village to track improvements as the work progressed.
During the first phase, the project team discovered:
- Severe H2S corrosion and deteriorating concrete.
- Significant leaks, with water gushing around pipes and pipe boots.
- Groundwater infiltration that was overwhelming the lagoon system.
The ART team used
OBIC 2210 chemical grout leak stop as it’s designed to seal high-pressure leaks. Water was shooting across the manhole from one side to the other, requiring multiple drill holes around the pipe openings to effectively seal off infiltration. Once dry, each manhole was lined with the OBIC Armor multi-layer system, providing a seamless, durable barrier against future water intrusion and chemical degradation.
The Village of Hamler selected ART to install OBIC Armor primarily for its ability to withstand H2S gases, which had been a primary culprit in the deterioration of their manholes. With SWAT testing certification and a 10-year warranty, OBIC Armor provided a long-term solution to protect and extend the life of their infrastructure.
Immediate and Measurable Impact
The impact of the rehabilitation was clear from the start. Within the first week of completing just 10 manholes, the village saw a 30,000-gallon-per-day reduction in infiltration into the lagoon system. By the end of the project, total daily infiltration, especially during rain events, had dropped from 168,000 gallons to 75,000 gallons—a massive improvement that relieved pressure on the wastewater treatment system and eliminated EPA concerns.
Encouraged by these results, Hamler is now planning further updates to its lagoon system and intends to continue rehabilitating the remaining manholes with active infiltration issues after the lagoon project is completed. With OBIC’s advanced products and ART’s expertise, the village has successfully extended the life of its infrastructure while improving operational efficiency.
