Brentwood’s StormTank product is a high-void, strong, affordable alternative to crushed stone, concrete structures or pipe chambers for subsurface storm water detention or infiltration. It offers the largest void space of any underground system currently on the market (97%) and has been load tested for use under parking lots and athletic fields with an HS-25 rating. The entire StormTank system is built on site from 18-in.-wide by 36-in.-long top/bottom panels and side panels made of rugged, lightweight polypropylene and 2 3/8-in.-diameter PVC columns (18- to 36-in. lengths).
