Prinsco offers four sizes of high-performance stormwater chambers designed for site-specific applications such as parking lots, roadways, and commercial developments. HydroStor chambers provide an environmentally sustainable underground water management system that optimizes groundwater recharge and saves valuable land resources. Our four storm chamber models are designed to fit almost any type of performance specifications, project footprint, and construction budget.
Prinsco’s chamber systems can be easily modeled with the HydroCAD Stormwater Modeling System and the Civil 3D Auto CAD Module. Both tools simplify the process of designing a system meeting specific storage and footprint requirements.
