The Recharger® 902HD is a 48" (1219 mm) tall, ultra-high capacity chamber which has been designed and tested in accordance with ASTM F2787 "Standard Practice for Structural Design of Thermoplastic Corrugated Wall Stormwater Collection Chambers".

The Recharger 902HD provides resistance to the loads and load factors as defined in AASHTO LRFD Bridge Design Specifications Section 12.12.

Typically when using this model, fewer chambers are required resulting in less labor and a smaller installation area. The Recharger® 902HD has the side portal internal manifold feature. HVLV® FC-48 Feed Connectors are inserted into the side portals to create the internal manifold.

The Recharger 902HD is available in only one model type and is open on both ends.
A separate end cap is required with this unit (sold separately) to cap the ends of rows.
