Grey water systems are systems that process grey water which is wash water or all wastewater except for toilet wastewater and food wastes from garbage disposal grinders. The water is not safe to drink but can be used for irrigation after water treatment and filtration through the system.

There are many different filtration and treatment technologies available depending on what the water will be used for.
