PORTLAND, Maine — Designing in high-performance, low headloss stormwater treatment is now simpler and quicker for drainage design consultants with the launch of an online sizing tool for the Downstream Defender® from Hydro International, according to a press release.

The Downstream Defender® Sizing Calculator empowers designers to select and specify the most appropriate Downstream Defender® model size needed with the option to generate product drawings, save project designs and submit projects for design reviews and price estimates, reported the release.

The Downstream Defender® is a high-efficiency manhole-based hydrodynamic vortex separator that offers particulate stormwater pollutant removal in a small footprint with minimal headlosses, the release noted.

According to the release, engineers can size Downstream Defender® models in the software according to many various city and state regulatory agency requirements.

“Before the launch, we trialed the online tool with more than 200 users and consulting engineers and received a very positive response,” comments Lisa Lemont, Hydro business development manager. “They really liked being able to easily and rapidly test sizing options as well as getting all-important guidance on whether online or offline configurations would be best on any given project."
