Stormwater Vaults
Optimizing Storage Capacity
The Vault is an innovative stormwater storage product that increases storage capacity and reduces stone fill by eliminating the need for stone between rows. A major benefit of using Vaults for storage and infiltration is that they provide high-density storage while allowing access to the excavation floor for maintenance. Manufactured of fiberglass-reinforced plastic, the Vault optimizes system efficiency, lowers installation costs and can provide greater design options for stormwater detention.

Success Story
Saint-Ismier, France
One of the world’s largest technology companies turned to Xerxes’ French distributor when creating the stormwater management system needed at its new site in Europe. In turn, Eaux-Vives provided an underground system using the innovative vault chamber to create storage capacity of 325 cubic meters.
The double-barrel vault shape of this innovative product can maximize storage volume within a smaller footprint than most other stormwater products. Manufactured of lightweight fiberglass-reinforced composite material, an entire system can be installed within a matter of hours, while saving costs at every stage – shipping, excavation and installation labor and equipment costs. Additional costs can be realized at many sites because this product generally requires less stone backfill than most infiltration installations.
