Skyrocketing H2S Levels Prompt Emergency Manhole Repairs

By Jeff Griffin, Senior Editor | May 2014, Vol. 69 No. 5
A fully deteriorated manhole at Moody Gardens, Galveston, TX.

“Had the condition of the manholes been discovered earlier,” said Dupré, “they could have been rehabilitated by more economical methods. This illustrates why periodic annual assessments are so important to identify issues before they become more costly to remediate or even fail completely. Our firm knows that there are many different ways to properly rehab sewer structures so we have a complete tool box of rehabilitation methods we can deploy as required to offer the best possible solution.”

Workers were forced to execute an emergency repair of manholes in and around the Moody Gardens complex, including the famous “pyramids.”
