Prelos® – The Next Step in Sewer Evolution

Prelos: Pressurized Liquid-Only Sewer

Prelos: Pressurized Liquid-Only Sewer

The Modern Sewer Solution

Prelos is the answer for community sewer, offering low life-cycle and initial capital costs and enabling more cost-effective wastewater treatment. This technology is based on nearly four decades of proven sewer solutions. 

  • Pressurized liquid-only (effluent) sewer technology 
  • Eliminates the need for scouring velocities 
  • Small-diameter, liquid-only sewer lines follow grade and carry primary-treated effluent to the treatment facility 
  • Minimal community disruption during installation
  • 24 to 48hr reserve storage in each on-lot tank1 
  • Documented low life-cycle costs2 
  • Deferred capital costs on slow build-out developments 
  • Allows for smaller, lower-cost, highly efficient treatment plants3
