The Recharger® 330XLHD is a high-capacity, heavy-duty dry well chamber designed for residential stormwater management. Its large storage volume and compact footprint make it ideal for managing runoff from roofs, driveways, and other impervious surfaces.
CULTEC’s chambers may be used in residential applications to control rainwater collected from gutters and/or catch basins. The chambers collect and store the stormwater underground until the soil is able to accept it back into the ground. Puddles and saturated soil are eliminated as water is diverted into the chamber and recharged into the ground. CULTEC chambers are lightweight and easily transported by hand making them ideal to install in tight areas or where minimal site disturbance is desired.
