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 48-hr. reserve storage in each on-lot tank
  • Documented low life-cycle costs
  • Deferred capital costs on slow build-out developments
  • Allows for smaller, lower-cost, highly efficient treatment plants
