SDS’s original product GEOlight® was designed and engineered with the specific intention of protecting CSOs and saturated land from overloading by more extreme rainfall events. Unlike the antiquated drainage systems that many of our cities and towns are equipped with, our geo-cellular storage tank systems are designed to accept substantial and rapid influx of surface water, retaining this excess water until such time as it can be safely released.

Our GEOlight® and Rigofill systems store, under the ground, water which is unable to soak into the ground naturally and can later be allowed to infiltrate, under controlled conditions, or can be retained for subsequent use.
