S-29B Stormwater Chambers
Innovating with Next-Generation Plastics
Performance in stormwater management starts with product quality, and quality starts with innovation and advanced materials. With the S-29B chamber, Xerxes continues its history of outperforming the competition with next-generation materials. As the world’s first long-fiber thermoplastic chamber, it is far superior to plastic chambers. Availability is often second only to product quality. The new Xerxes manufacturing facility is in the U.S. so customers have chambers when and where they’re needed.

Success Story
Windsor, Pennsylvania
More than 2,000 S-29B chambers created a stormwater management system for a new recreation and park center in Windsor Township, Pennsylvania. They are building a recreation/park area for residents and Township buildings for residents.
Ready availability of the HydroChain chambers and the high-strength of the reinforced composite chambers were the main selling points for choosing these chambers. Xerxes’ expert engineering and sales teams worked closely with York Excavating, the project’s contractor on this project, which required a three-system installation to meet the site’s need for 27,000 cubic feet of storage.
