Challenge
Conrad, Montana, faced serious problems with its aging steel potable water storage tank serving as the community’s primary drinking water source. Leaking seams and corrosion threatened long-term reliability, prompting the need for a protective lining solution that would restore structural integrity and ensure safe potable water storage.
Results
Using OBIC Armor’s multi-layer lining, Advanced Lining restored the wet well in one summer, sealing cracks, preventing leaks, and extending the longevity of the wet well by decades all with a quick, trenchless process that reduced costs and disruption.

About The Company
Advanced Lining is a certified installer specializing in infrastructure restoration using advanced protective coatings and linings. The company partners with industry leaders like OBIC to deliver durable solutions for critical municipal assets.The Challenge
In the mountainous region outside Bozeman, Montana, a 40’ x 40’ bolted steel potable water tank served as the only drinking water supply for the surrounding community. Over time, the tank developed leaks that led to exterior corrosion and raised concern about long-term durability and potential replacement costs. Access to the site posed additional challenges. The tank was located on top of a hill with limited road access, requiring careful equipment transportation planning and a wrecker on standby as a precaution. The project timeline was further impacted when the subcontracted sandblasting crew experienced an unexpected staffing emergency, slowing initial surface preparation operations. Despite logistical complexity and schedule uncertainty, maintaining uninterrupted water service was a priority. Peak Water, the community’s water system operator and sister company to Advanced Lining, handled flow bypass operations
to keep potable water available during rehabilitation
The Solution
To address corrosion, sealing failures, and long-term protection needs, the community partnered with Advanced Lining, an OBIC-certified installer serving Utah, Idaho, Wyoming, and Montana. The rehabilitation followed a precise coating protocol that included surface preparation, application of OBIC potable water primer, sealing of all seams and bolt heads with OBIC 1306 closed-cell polyurethane foam, and a final OBIC 1100 NSF/ANSI 61-certified polyurea topcoat for durable corrosion resistance and safe potable water containment. Despite scaffold and scheduling challenges, the project was completed in approximately 20 days while maintaining strict safety and quality standards.
The Results
The completed lining system eliminated leaks and stopped corrosion, extending the tank’s service life and avoiding costly replacement. Using OBIC’s potable water coating system, the community achieved long-term corrosion protection, permanent sealing at seams and penetrations, NSF/ANSI 61 compliance, reduced maintenance costs, and enhanced structural reliability. With OBIC-certified installers like Advanced Lining, municipalities can rehabilitate aging water infrastructure cost-effectively while maintaining safety, water quality, and operational continuity.
