Hydro Launches Online Sizing Calculator

Downstream Defender Sizing Calculator takes users through the selection and sizing process

Hydro Intl. Downstream Defender Online Sizing Calculator

Designing in high-performance, low headloss storm water treatment is now simpler and quicker for drainage design consultants with the launch of an online sizing tool for the Downstream Defender from Hydro Intl.

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.

The Downstream Defender is a high-efficiency manhole-based hydrodynamic vortex separator that offers particulate storm water pollutant removal in a small footprint with minimal headlosses. Engineers can size Downstream Defender models in the software according to many various city and state regulatory agency requirements.

The Downstream Defender Sizing Calculator takes the user step-by-step through the selection and sizing process with options to size by regulatory agency, target particulate pollution by particle size, or simply by the required Downstream Defender model, if known. The software also makes suggestions for the suitability of either continuous online or offline drainage layout options. The designer can then generate detail drawings with standard or site-specific elevations and a written specification for ease of use in project proposals.

A simple log-in procedure for the Downstream Defender Sizing Calculator on the www.hydro-int.com website sets up a secure account resource unique to each engineer, allowing the build-up of a library of design iterations to be stored for past and current projects. It is easy to customize the inlet and/or outlet pipe size, the elevations of the inlet and outlet pipes and the manhole cover based on site-specific topography.

Editing is rapid, so that project details can be added and amended as a storm water site design progresses. Once a design is complete, users may opt to submit their design for a free review and price estimate by Hydro’s Technical Support Team.

The Downstream Defender is proven to be more efficient than other structural treatment devices in as little as half the footprint. Headloss is very low making it ideal for use on drainage lines with shallow grades. The Downstream Defender is in service both nationally and internationally for protecting drainage and watercourses from sediment and pollution loads.
