Wastewater Series: How Geomembranes help to improve water quality, lower costs and increase efficiencies in wastewater treatment
Part 1: Wastewater Industry in North America
The terms attachments, penetrations and terminations are often considered synonymous, or at least in the same family, when used in the context of geomembranes. This post will focus on attachments and specifically a review of ASTM D6497, one of the main guides for geomembrane mechanical attachments.
As Engineers, we use the term “failure” in a number of ways but know that it implies something did not perform as expected. Was it the fault of the “failed” thing or action, or was it a failure in how it was expected to perform, under those conditions? Regardless, we all know that failure brings negative connotations in many ways, and none are desirable.
Resiliency in drinking water systems has become a broad discussion as many systems have experienced operational and quality problems. Like much of our ageing infrastructure, the backlog of needed updates and repairs continues to grow.
Geomembrane warranties are typically provided by the manufacturer. Standard warranties are usually included at no additional cost and vary among manufacturers and products, in coverage, duration and other factors. It can be confusing trying to understand what a warranty really says. What needs to be considered when evaluating a geomembrane warranty?
Our team was recently invited to speak with Shannon Oelkers from Integrity Environmental on their podcast Tank Talk regarding XR® Geomembrane liners and how they perform in extreme environments.

October 18, 2022, marked the 50th anniversary of the passage of Public Law 92-500, commonly known as the Clean Water Act (CWA). It was a broad initiative which sought to put the country on a new path to correct the lack of attention to maintaining the waters of the United States.
