Cistern
Definition and meaning of Cistern in real estate.
A cistern is a storage tank designed to collect and store water, typically rainwater, for later use. They can be located above or below ground and are often used in rural areas or sustainability-focused properties for non-potable or potable water needs.
In more detail
Cisterns are common in regions without access to municipal water systems or productive water wells. They collect rainwater from roof gutters and channel it into a concrete, plastic, or metal tank. The stored water can be used for irrigation, toilets, or fire protection, and with proper filtration, it can even serve as household drinking water.
Buyers considering a property with a cistern should inspect the tank for cracks, ensure the pump functions properly, and test the water quality. Maintenance includes regular cleaning to prevent algae growth and sediment buildup.
