Municipal Wastewater
Treatment Plant Liners &Cover Systems
16,000+ publicly owned treatment works across the US rely on engineered liner and cover systems. EFI provides lagoon liners, floating covers, and permeable cover technology for municipalities nationwide.
The Challenge
Aging Infrastructure Meets Growing Demands
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.
- Aging lagoon liners require replacement to prevent groundwater contamination
- Odor complaints from H₂S drive community pressure on municipal operators
- Algae growth reduces treatment efficiency and causes permit violations
- Insufficient contact time compromises disinfection performance
Municipal Wastewater by the Numbers
