Stormwater system 
The CULTEC Recharger® and Contactor® underground chambers are designed to replace conventional stormwater management systems such as ponds, swales, pipe, and stone trenches. The Recharger 150XL, 180, 280, 330, V8, and 900 HD models are high-profile, high-capacity chambers. The Contactor EZ-24, 100, 125, and Field Drain C-4 are lower profile, lower capacity chambers that can accommodate systems with high water tables or other depth restraints or when a larger infiltrative surface area is required by design. The entire recharger series and the Contactor 100 include an internal manifold, using side portals located on each chamber for maximum design flexibility and decreased installation footprint. This eliminates the need for costly fabricated pipe manifolds. It also reduces the required bed size by placing the manifold within the bed of chambers. The recharger and contactor series offer maximum infiltration capability due to their fully open bottoms and perforated sidewalls. They are lightweight and designed to be installed easily in trench or bed configurations, according to site restrictions or client preference. CULTEC (Brookfield, Conn.).
