Spirolite® HDPE Structures: Manholes, Risers, Wet Wells and Lift Stations
Spirolite® HDPE structures are lightweight, corrosion-resistant, and built to perform—including manholes, wet wells, lift stations, and risers.
Spirolite® HDPE structures offer a smarter alternative to precast concrete for a wide range of fluid conveyance applications. Whether you need a leak-free manhole, a high-performance wet well, a custom-fabricated lift station, or riser, Spirolite delivers. Manufactured from spirally wound HDPE, Spirolite structures are lightweight, highly durable, easy to install, and built to meet exact project specifications. With options for bell and spigot or welded joints, custom stub-outs, riser heights, and internal platforms, Spirolite structures reduce installation costs and outlast legacy materials in even the most aggressive environments.
Spirolite HDPE Structure Applications
- Sanitary sewer manholes
- Stormwater access risers
- Lift station wet wells
- Bypass and overflow tanks
- Odor control and vent stacks
- Industrial wastewater access points
- Landfill leachate collection risers
Why Choose Spirolite for Vertical Structures

HDPE withstands hydrogen sulfide, chemical exposure, and groundwater intrusion without coatings or liners.
Specify pipe sizes, riser heights, access covers, internal components, and mounting hardware—built to match your system.
Most units can be offloaded and placed with minimal equipment, saving time and equipment costs.
Bell and spigot or extrusion-welded joints deliver leak-free systems for 100+ years.
Spirolite structures arrive fully fabricated with access ports, stubs, ladders, and platforms already installed.
Trusted in wastewater plants, landfill operations, stormwater systems, and industrial facilities.
Project Spotlight: Laguna Beach Lift Station
A 120” Spirolite® HDPE lift station installed below ground in Laguna Beach, California, featured two 10-foot diameter wet wells: a primary lift station structure and a bypass wet well. The bypass structure was engineered with internal piping, ladders, a fiberglass platform, and a specialized valving system—allowing it to serve as a backup manhole in emergency overflow conditions.
