Location

Lakeside, Montana, just south of Kalispell at Flathead Lake

Description

This structure was experiencing extensive hydrogen sulfide and sulfuric acid deterioration at the sewage treatment lagoon head works.

Solution

The Poly-Triplex Certified Installer was contracted to line the structure with the Poly-Triplex Liner System. The liner was installed and has stopped all deterioration from hydrogen sulfide and sulfuric acid in the structure. This was a considerable savings over removing and replacing the structure, which would have cost several thousand dollars more.

Benefit

The problem was solved and it cost the sewer district much less than anticipated.

Comments

Lakeside Water and Sewer District was very pleased with the results and completed the project at significantly lower cost than replacement. Poly-Triplex provided a more permanent solution than new construction and provided a 10-year warranty, a warranty that was not possible with remove and replace.
