Quick Answer
Dispose of non-usable grey water by burying it at least 4 feet underground, away from water sources and sensitive ecosystems, or use it for irrigation and flushing toilets after treating it with natural or chemical methods.
Choosing a Disposal Method
When deciding on the best method to dispose of non-usable grey water, consider the environmental impact and local regulations. Burying grey water 4 feet underground can be an effective solution, but ensure it’s at least 100 feet away from any water sources, such as wells or rivers. This method also requires careful placement and maintenance to prevent contamination.
Treating Grey Water for Irrigation
If you choose to treat grey water for irrigation or flushing toilets, consider using a natural filtration system or adding a chemical treatment, such as chlorine or ozone, to kill bacteria and viruses. Use a treatment capacity of 1-2 pounds of chlorine per 1,000 gallons of grey water. Regular maintenance of the treatment system and monitoring of water quality are crucial to prevent contamination.
Designing a Grey Water System
Design a grey water system that separates clean and non-usable water streams. Use separate pipes for washing machines, sinks, and showers, and install check valves to prevent backflow and contamination. Consider implementing a grey water tank with a pumping system to facilitate reuse.
