Storm Sewer

The best storm sewer solution is the one that matches the project’s hydraulic, structural, and installation requirements without forcing tradeoffs you cannot accept in the field.

For many civil site projects, that means starting with a system that delivers improved hydraulics, dependable structural capacity, and product options for different cover depths and site constraints. Contech offers storm sewer solutions and pipe systems built around those decision points rather than a one-size-fits-all answer.

Hydraulics matter most when slope is limited, cover is constrained, or the design team is trying to move more flow without oversizing the system.

A smooth interior can improve flow efficiency and help you manage grade, excavation, and structure depth more effectively. That is one reason Contech’s storm sewer portfolio emphasizes smooth interior performance in multiple product lines, including ULTRA FLO®, which is positioned for storm sewer applications where hydraulic efficiency and structural strength both matter.

Structural capacity becomes the deciding factor when you are dealing with heavy traffic loading, deep bury applications, challenging backfill conditions, or long-term performance expectations under pavement.

This is where product differences start to matter quickly. Contech gives engineers options that address different structural demands, including corrugated metal pipe for broad strength ranges and DuroMaxx® SRPE for applications that call for steel reinforcement with a smooth interior. If your project includes unusual loading, narrow windows for construction, or deep cover, add project-specific calculations early.

Joints matter because storm sewers do more than convey runoff. They also need to protect alignment, reduce infiltration risk where required, and support long-term system reliability.

In practice, joint selection affects installation speed, maintenance exposure, and confidence in the finished system. Contech highlights watertight and performance-oriented joint options across different pipe families, including A-2000™ and DuroMaxx®, so the joint decision can match the project requirement instead of becoming an afterthought. If joint performance is critical on your job, define that requirement early in design and review it alongside material and profile selection.

For deep bury applications, the first option to review is usually the one that combines structural strength with the hydraulic performance your layout requires.

Contech gives you more than one path. Corrugated metal pipe is used across storm sewers and other buried infrastructure where strength and service-life options are central to the design. DuroMaxx® SRPE systems show how Contech applies steel reinforcement, smooth interior performance, and joint options in demanding buried applications.
