Significantly reducing the high cost of rebuilding infrastructure

WPL can retrofit into any on-site vessels regardless of shape or size.  Key advantages include a significant reduction in the high cost of rebuilding infrastructure, size of footprint and electricity consumption whilst increasing the overall process capacity of the plant and improving environmental compliance

Our service extends to the hire of packaged wastewater treatment to ensure your site is not disrupted and compliant during a repurpose project.


  • Utilities and municipal
  • Commercial

Enhanced WPL Hybrid-SAF™ technology
