Underground Water Tanks

An underground storage tank is a container used to house liquid substances for preservation, treatment and use at a future date. Underground storage tanks typically store petroleum and hazardous chemical substances.These tanks can be constructed of concrete blocks or with other materials. The tanks are partly (1.5 m) built below the soil surface. These tanks can store up to 20,000 liters of water, used for domestic use and crop cultivation. Water extraction can be done with handpumps or small and efficient motor pumps.
