Geomembranes Aid in the Success of Lagoon Wastewater Treatment Systems

Posted by Felon Wilson on Jan 18, 2023 8:22:48 AM

In October 2022, the U.S. Environmental Protection Agency (EPA) announced $2 million in research grant funding as part of their Lagoon Wastewater Treatment Plan. The grants are one component of the EPA’s Lagoon Wastewater Treatment Action Plan, a broad initiative to assist small, rural, and tribal communities with the utilization of lagoon wastewater systems.

4 Potential Stresses and the 3 Strategies for Preventing Geomembrane Mechanical Failure

Posted by Felon Wilson on Feb 15, 2022 9:29:46 AM


Many engineers would argue that geomembranes are only fluid barriers and are not meant to be load bearing in any manner. All loads should be carried by geosynthetic counterparts, such as geotextiles, geogrids, etc., that are placed over and under the geomembrane. However, from a materials and installation standpoint, it is virtually impossible to transmit all load to the adjacent layers. Additionally, it is not usually cost-effective to build a heavily redundant composite system that takes all mechanical bearing off the geomembrane.
