The Challenge

Problem

Rayonier's Fernandina Beach specialty cellulose mill required expansion of its wastewater containment capacity to support increased production volumes. The existing lagoon system, originally lined by EFI, needed a new cell added and two existing cells rehabilitated to extend their service life. Florida DEP required the expansion to meet updated containment standards including secondary containment and enhanced leak detection.

Our Approach

Solution

EFI returned to the Fernandina Beach facility to install a new 280,000 SF lined lagoon cell with double composite liner, leak detection, and leachate collection. Two existing cells received liner rehabilitation including patch welding, anchor trench repair, and new monitoring wells. All work was coordinated around continuous mill operations to avoid any production impact.

Key Outcomes

  • 280,000 SF new double-lined lagoon cell
  • 2 existing cells rehabilitated
  • Updated to current Florida DEP standards
  • Leak detection and monitoring installed
  • Zero production impact during construction
  • Extended facility containment capacity by 40%
“We brought EFI back because they built the original system and know our site better than anyone. The expansion was seamless — our mill never missed a beat during construction.”
