Cistern Location on Property: What Are the Best Practices?

April 5, 2026

Quick Answer

When selecting a location for a cistern on your property, consider placing it on high ground to prevent waterlogging, ideally with a slight incline to allow for drainage. This location should also be far from potential contamination sources like septic systems, wells, and animal enclosures. A suitable location can be determined by assessing the topography of your property.

Choosing a Site for the Cistern

When selecting a location for the cistern, ensure that it’s situated 10-15 feet away from any potential contamination sources, such as septic systems and wells. This distance will prevent cross-contamination and ensure the water quality remains safe for consumption. It’s also crucial to position the cistern in a spot that allows for easy maintenance and access.

Considering Topography and Slope

The ideal location for a cistern is on high ground, with a slight incline to prevent waterlogging. A gentle slope of 1-2% will allow water to drain away from the cistern, reducing the risk of flooding. This slope should also be considered when designing the cistern’s drainage system to ensure efficient water flow.

Additional Requirements

In addition to the site selection, ensure that the cistern is positioned in a spot that receives minimal direct sunlight. This will help prevent algae growth and maintain water quality. The cistern should also be partially shaded to reduce evaporation and prevent water loss.
