Challenge

The Village of Hamler, Ohio, was experiencing extreme hydrogen sulfide (H₂S) corrosion and groundwater infiltration, leading to 168,000 gallons per day of excess water entering the lagoon system during rain events. This overwhelmed the system, risking EPA compliance violations and costly repairs.

Results

Significant Infiltration Reduction: Within a week of completing the first 10 manholes, daily infiltration decreased by 30,000 gallons. By project’s end, rain-event infiltration dropped from 168,000 to 75,000 gallons per day. Restored EPA Compliance: Reduced excess water allowed the lagoon system to function properly. Long-Term Protection: OBIC Armor’s SWAT-tested durability and 10-year warranty ensure lasting results. Cost Savings: Rehabilitation prevented an expensive full replacement, saving the village significant funds.

The Solution

OBIC Hamler_Before and After 1024x768

Seeking a durable and cost-effective solution, the Village of Hamler partnered with Advanced Rehabilitation Technology (ART), an OBIC-certified installer, to restore 25 of its 100 manholes. ART implemented OBIC's high-performance lining solutions, applying OBIC 2210 Leak Stop Grout to seal high-pressure leaks and installing the OBIC Armor multi-layer system to create a seamless, long-lasting barrier. This approach was executed in increments of 10 manholes, allowing for real-time monitoring and adjustments.
