What is a cistern hole?

A cistern hole is a cavity or opening in a cistern, which is a large water storage tank or reservoir. Cistern holes are typically located at the top of the cistern, allowing water to be poured in for storage. They may also be used for monitoring the water level or accessing the interior of the cistern for cleaning or maintenance.

Cistern holes can vary in size and shape, depending on the design of the cistern. Some cisterns have a small, circular hole with a lid that can be opened and closed, while others may have a larger opening that requires a ladder or other equipment to access.

Cistern holes are essential for filling and maintaining the water supply in a cistern. They are often equipped with filters or screens to prevent debris and contaminants from entering the cistern along with the water. Proper maintenance and regular cleaning of cistern holes are important to ensure the quality and safety of the stored water.
