The LemTec™ Gas Cover System is comprised of a custom-engineered, rigid, durable geo membrane cover that isolates liquid in lagoons and tanks from ambient air, allowing no diffusion of odor vapors, and a piping system to draw off gas produced under the cover using negative pressure. An LET gas cover can be paired with a LemTec™ Modular Insulated Cover System for heat retention to maintain optimal digester performance or for additional protection of gas collection from ice, debris, and UV. Access ports can be designed into the system for equipment maintenance and sampling, and the cover itself is easy to remove for tank or lagoon maintenance.

Each LET wastewater treatment process and technology, including the LemTec™ Gas Cover System, is custom designed with our Advanced Integrated Lagoon Technologies (AILT) approach. The AILT approach allows us to integrate cutting edge technologies, such as our gas containment and collection covers in combination with over 30 years’ proven experience to deliver guaranteed results that meet each of our clients’ unique needs.
