Municipal Wastewater
16,000+ publicly owned treatment works across the US rely on engineered liner and cover systems. EFI provides lagoon liners, floating covers, and patented permeable cover technology for municipalities nationwide.
The Challenge
Municipal wastewater treatment plants across the country face aging lagoon infrastructure, tightening discharge limits, and growing odor complaints from expanding residential development. Many facilities need liner replacements, cover upgrades, or treatment improvements without the budget for full plant reconstruction.
Algae blooms, odor emissions, and insufficient contact time for disinfection are common challenges. EFI's engineered cover and baffle systems solve these problems at a fraction of the cost of mechanical treatment upgrades.
Our Solutions
EFI provides a complete range of geosynthetic liner and cover solutions for municipal wastewater treatment plants, including our patented permeable cover technology that eliminates algae growth and controls odor without rainwater pumping.
HDPE, XR-5, and RPE geomembrane liners for treatment lagoons, equalization basins, and storage ponds. NSF-approved materials for potable water contact applications.
Sealed floating covers for odor control and biogas capture at anaerobic and facultative treatment lagoons. Eliminates H₂S complaints and controls algae growth.
EFI's patented permeable cover system (US Patent 6,558,548) controls odor and algae while allowing rainwater pass-through — no pumping infrastructure required.
Geomembrane baffle curtain systems that increase effective contact time for chlorine disinfection and improve nutrient removal without additional treatment capacity.
Patented Technology
Project Spotlight
EFI designed and installed a 307,661 square foot floating cover system for the Johnston County, North Carolina raw water reservoir — one of the largest municipal cover installations in the Southeast. The cover system controls algae growth and protects water quality for the county's treatment plant intake.
