Cost and ease of installation/maintenance are major limiting factors in the widespread use of domestic greywater remediation systems. Introducing people to concepts and technologies that allow them to experiment with greywater on a relatively small scale can act as a gateway to larger — possibly collective — actions towards sustainable water use.
The proposed remediation system is an under-the-kitchen-sink tiered wetland. The roots of wetland plants like alfalfa, water hyacinth, and pickerel weed naturally clean drain water. A five gallon tank stores water that can then be used in gardens. Any overflow goes back into the normal plumbing and into the municipal waste stream.
