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
Prelos Processor:
The Prelos Processor is the core of the Prelos Wastewater Collection System. With the Prelos Processor, we've brought the ease of specifying, installing, operating, and maintaining a liquid-only sewer to a whole new level. Components are included and designed to work together - simply, durably, and efficiently.
- High-quality, watertight tank package
- Unique “meander” design for superior solids removal and primary treatment
- Only liquids are conveyed to the treatment facility
- Easy to maintain, with compatible, long-lifespan components
- Single riser and lid provide access to all components
- Lightweight, easily rebuildable effluent pump can last more than 25 years4
- Optional industry-leading, extended 10yr limited pump warranty available
- Single line-item that’s easy to specify
Based on average flow of 150 gpd (568 L/day) per household.
