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