The StormTech MC-4500 chamber from Advanced Drainage Systems provides designers with a cost-effective method to save valuable land and protect water resources. It is primarily designed to be used under parking lots, thus maximizing land usage for commercial and municipal applications. At 60 inches tall and 100 inches wide, it optimizes water-quality assurance with fast, easy installation and a minimum 50-year service life. To help designers, owners and contractors design conceptual layouts and estimate costs, the ADS StormTech Design Tool is available. The initial layouts can be refined or customized by the designer or as requested. The design tool can be the first step to evaluating conversion opportunities to determine the feasibility of retention pond replacement, alternative underground products, public safety or water harvesting. 800/821-6710; www.ads-pipe.com.
