Chattanooga TN - Waste Treatment Plant
Extreme Exposure to H2S (Hydrogen Sulfide)
The hole was installed in 2005 at the Chattanooga waste treatment plant. This hole is the last access point just prior to the waste separator. As you can see from the video, this site has extreme hydrogen sulfide gas content. This extreme exposure decay the traditional concrete rings which the municipality had to repair on a yearly basis. The UGT rings have survived the test of time with only discoloration.
