As land prices rise and project footprints shrink, developers and engineers are forced to rethink traditional stormwater management. Gone are the days when an open detention basin in the back corner of the site was the default. The trend is shifting underground, and for good reason. Corrugated metal pipe (CMP) detention and infiltration systems provide a solution that helps maximize usable land, comply with regulations, and reduce long-term maintenance costs.

Stormwater design isn’t always straightforward. Between utility conflicts, easement restrictions, odd property lines, and topography, most sites require more than a one-size-fits-all solution. That’s where the flexibility of corrugated metal pipe (CMP) comes in.

When it comes to underground stormwater systems, longevity depends heavily on material selection. While all corrugated metal pipe (CMP) systems offer structural integrity, the right coating ensures they perform for decades in the specific environmental conditions of your site. This article breaks down the main CMP coating types, their performance in different soil and water conditions, and when to use each.

When it comes to stormwater management and culvert design, selecting the right pipe material is crucial for performance, longevity, and cost-effectiveness. Enter Aluminized Type 2 (ALT2) pipe—a material that has become a staple in civil engineering projects. But what makes it so special? This blog will cover everything you need to know about ALT2 pipe and why it’s often the top choice for stormwater and drainage systems.

Red flags are design elements that are commonly or easily overlooked and may need extra attention when designing. Considering the red flags upfront will expedite the design and fabrication process, and eliminate delays, installation, and performance issues.

Corrugated metal pipe (CMP) is the “go-to” material for most stormwater detention and infiltration projects. A wide range of gages, corrugations, and diameters

Stormwater detention systems often include a large portion of the storage volume within the voids of the backfill material. Depending on the underground
