What is a cistern?

A cistern is an underground container that is designed to collect and store rainwater or other types of water. It is typically made of concrete, brick, or other durable materials, and it may be lined with a waterproof membrane to prevent leaks.

Cisterns are commonly used in areas where water supplies are limited or where water is not readily available. They can be used for a variety of purposes, including irrigation, firefighting, and drinking water storage.

Cisterns are typically connected to a roof or runoff system, which directs rainwater into the container. The water is then stored until it is needed, at which point it can be pumped out for use.

While cisterns are a useful way to conserve water and reduce water bills, they do require maintenance to ensure that they remain clean and free of debris. Regular cleaning and disinfection are necessary to prevent the growth of bacteria and algae, which can contaminate the stored water.
