DuroMaxx® Stormwater Detention and Infiltration

DuroMaxx steel-reinforced polyethylene (SRPE) pipe combines steel and polyethylene (PE) to make an exceptionally strong and durable pipe for stormwater detention and infiltration applications. DuroMaxx is unique as it has fewer joints to assemble on site, can be made watertight, and can be used in applications with corrosive soils.

DuroMaxx SRPE Pipe for Stormwater Detention and Infiltration

Eighty (80) ksi steel reinforcing (SR) provides the strength; pressure rated polyethylene (PE) resin provides the durability. The combination of materials results in an extraordinarily strong and durable pipe that sets a new industry standard for stormwater detention and infiltration applications.

DuroMaxx provides the lightweight, durability of traditional HDPE with the added structural strength of steel, making it the perfect choice for deep burial and corrosive soil applications.

DuroMaxx detention and infiltration systems can be designed with gasketed bell and spigot joints or welded coupler joints for increased water tight reliability. DuroMaxx is available in diameters ranging from 30 to 120 inches and in lengths up to 48 feet. Larger diameter pipe provides increased storage volume in a smaller footprint, while long pipe lengths reduce the number of sections to be set and joints to assemble.

DuroMaxx Features - Benefits

  • Twice as stiff as traditional HDPE pipe- requires less structural backfill.
  • Corrosion resistant HDPE - can be used in applications with corrosive soils.
  • Several joint configurations - 30 psi welded coupler (WC), 15 psi high performance (HP), 3 psi low head (LH) and soil tight (ST) joints available.
  • 48 foot pipe lengths - fewer joints to assemble on site, resulting in faster installation rates.
  • Lightweight - easily handled and quickly installed.

DuroMaxx for Stormwater Detention

DuroMaxx stormwater detention systems store stormwater runoff exceeding a site’s allowable discharge rate and release it slowly over time. Installed below grade, stormwater detention systems maximize land usage and help meet water quantity requirements.

DuroMaxx for Stormwater Infiltration

Perforated DuroMaxx infiltration systems store stormwater runoff in the pipe and surrounding stone during a storm until it can be released slowly into the surrounding native soil. Perforated CMP is often used to meet Low Impact Development requirements.

DuroMaxx for Combined Sewer Overflow

DuroMaxx can provide storage for combined sewer overflow (CSO) via underground storage tanks. DuroMaxx vessels are both durable and water tight, providing a cost-effective way to handle this critical problem. With diameters of up to 120" and flexible design configurations combined with its watertight joints, DuroMaxx is an ideal solution for CSO storage.

DuroMaxx for Rainwater Harvesting Cisterns

The UrbanGreen Rainwater Harvesting cistern is made from DuroMaxx Steel Reinforced Polyethylene (SRPE).  The eighty (80) ksi steel reinforcing ribs provide the strength and pressure rated polyethylene (PE) resin provides the durability. The combination of materials results in an extraordinarily strong and durable below ground cistern. SRPE cisterns can be designed in any length and configuration to suit project storage and layout requirements.
