The step-by-step Flexstorm Product Configurator online software program from Advanced Drainage Systems Inc. (ADS) allows users to select the proper components and design an inlet filter unit for a stormwater drainage system and to be configured based on drainage structure type and filtration needs. The program is available for free at www.inletfilters.com. The resources section contains product details, engineering drawings, specifications, educational videos, plus operation and maintenance plans. Because components are configurable and adjustable, units are designed to fit any drainage structure.
