The StormTank Pack stormwater management system from Brentwood is designed for non-load bearing, subsurface applications, including infiltration and integration in bioretention and rainwater harvesting applications. The system yields a 95 percent void space and utilizes crossflow media, evenly distributing stormwater runoff to the base. It can accommodate layout variations, be cut to any length and does not require assembly. 610/374-5109; www.brentwoodindustries.com.
