Applications
Spirolite® HDPE Stormwater Detention
Spirolite® HDPE stormwater detention systems are lightweight, durable and designed for easier and faster installs with long-term, leak-free performance.
Spirolite® HDPE systems offer an advanced solution for underground stormwater detention, retention and CSO (combined sewer overflow) management. Fabricated from spirally wound, profile-wall HDPE pipe, Spirolite has been engineered to resist corrosion, install quickly, and last 100+ years. Compared to concrete or steel systems, Spirolite is easier to handle, require less equipment and arrives jobsite-ready in long lengths with fewer joints--ideal for municipal infrastructure, commercial developments and environmental containment projects.
Spirolite HDPE Stormwater Applications
- Detention and retention basins
- Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) storage
- Equalization and surge tanks
- Emergency runoff capture
- Underground stormwater reuse systems
- Commercial site drainage
