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 ^[1]. 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.
