Floating Modular Cover Systems

Lemna Technologies was the first company to offer covers designed as a floating modular system for the wastewater industry. Their patented covers feature individual casings that are uniquely fastened together to form a floating system that completely covers the liquid in the basin. The individual casings include closed-cell insulation sealed between two sheets of durable geomembrane that are long lasting and require no maintenance.

Cost-effective, easy to install, and reliable; LemTec™ Modular Insulated Covers are the industry leader in cover technology. Their innovative design addresses these common problems and issues.

  • Heat Loss

    Heat is retained through proper insulation.

  • Equipment Accessibility

    Custom hatches provide access to submerged or floating equipment for maintenance or repair, or access to fluids for sampling purposes.

  • Inconsistent Water Levels

    Floating covers self adjust as fluid levels vary.

  • Trapped Gas

    Gas escapes between the casings and is not trapped inside where it could cause ballooning.

  • Rainwater Collection

    Rainwater passes between casings, which eliminates the need for rainwater collection pumps.

The LemTec™ Modular Insulated Cover can be cost effectively installed by a small crew, with no heavy equipment, and over basins of any size, with any water level. The pre-manufactured panels require no field welding during installation. Their unique design also allows for easy repair, if required, since only affected casings need to be removed, not the entire cover.
