Quick Answer
DESIGN A GREY WATER SYSTEM FOR A TINY HOME BY ROUTING WASHBASIN AND SHOWER WATER TO A SEPARATE TANK AND USING A SUBMERSIBLE PUMP TO DISTRIBUTE IT TO A DECANTER OR BIOROCK SYSTEM FOR SAFE REUSE IN TOILET FLUSHING.
System Components
A typical grey water system for a tiny home consists of a washbasin and shower water collection tank, a submersible pump, a decanter or Biorock system, and a distribution pipe network. The collection tank should be sized based on the water usage of the household, typically a minimum of 10-20 gallons (38-76 liters) to accommodate 1-2 people. A submersible pump with a flow rate of 5-10 gallons per minute (19-38 liters per minute) is sufficient for most tiny homes.
System Design and Installation
When designing the system, consider the slope and elevation of the collection tank and distribution pipes to ensure gravity-fed flow. The decanter or Biorock system should be installed below the collection tank to facilitate gravity flow. The distribution pipe network should be sized to accommodate the flow rate of the submersible pump and the needs of the household. Consider using 1/2-inch (13 mm) or 3/4-inch (19 mm) PEX tubing for the distribution pipes.
Water Treatment and Safety
The decanter or Biorock system is responsible for treating the grey water to remove solids, bacteria, and other contaminants. Regular maintenance and monitoring of the system are crucial to ensure safe and effective treatment. It’s recommended to test the water quality regularly and perform routine cleaning and maintenance of the system to prevent clogging and contamination.
