Where is greywater stored?

Greywater is typically stored in a designated tank or cistern, which can be above or below ground. These storage systems are designed to hold water from sources like sinks, showers, and washing machines, while filtering out solids and contaminants. Proper design ensures that the greywater is kept separate from blackwater (sewage) and is often equipped with features to prevent odor and promote safe reuse for irrigation or other non-potable purposes.
