SPELChamber is an open bottomed, high-density polyethylene infiltration chamber for subsurface retention or detention of storm water runoff. It provides an environmentally progressive and technologically advanced storage and pollutant removal solution – yet it is more cost-effective and requires less maintenance than other types of underground stormwater management systems.

The SPELChamber reduces nutrient and other pollutant loadings by taking advantage of the natural biological and physical properties of the soil, directly comparable to the functions of a septic drain field. It also recharges groundwater drinking supplies, while concurrently helping to maintain base flow to streams, wetlands, lakes, and ponds, and to counter saltwater intrusion.
