When it comes to designing large storm sewer conveyance systems, did you know there are alternatives to reinforced box culverts?   For years, Contech has worked with engineers and agencies across the country on finding efficient and effective ways to move stormwater.   Traditionally, you may be used to defaulting to concrete when looking at larger

I recently had the opportunity to host a national webinar on the topic of Ports & Airports and thought it would be a good idea to mention some of the items that were discussed on the Pipe Blog for those who may have missed it. Ports and Airports are like little cities with both little and big problems. These issues can vary quite vastly, but there

Skiers and children on sleds love a slope on a snowy day, while grounds keepers dread the slopes in mowing season. Slopes are part of our landscape, and we need to deal with them. This applies to the design of a culvert installation as well, particularly when the slope is going across the culvert side-to-side, as opposed to being along the length

First thing’s first, let’s talk about some basic hydraulics. Most shorter length culverts are inlet controlled and just about all storm sewers are outlet controlled. So for storm sewers, the flow is limited by the outlet conditions of the pipe and the roughness inside the pipe matters. The primary method to determine the flow rate (Q) of a storm

The design, manufacture and installation of Concrete, Corrugated Steel, Plastic and Steel Reinforced Polyethylene pipe happens every day for storm sewers and culverts. While most design engineers spent many hours in college learning about hydrology and hydraulics, how many spent time studying the buoyancy of pipe materials in the field? While most
