About Underground Water Tanks

To install underground tanks, a hole is dug and the tank is placed below ground level. Water flows through an input pipe and into the top of the underground tank. Before the water enters into the tanks it passes through a screen that filters out any leaves or other debris. The water rises until it reaches the top of the overflow pipe, located in the middle of the tank. Once the underground tank is full, the extra water flows into the overflow pipe and out to a designated area on your property. All underground tanks utilize a submersible pump to pump water out of the tank. Underground water tank storage capacity ranges from 130 to 2800 gallons.
