For most of us, setting up a grey water system— that is, setting up a system to recycle waste water that's only slightly contaminated to use for flushing a toilet or watering plants—is too complicated. Water Legacy aims to change that by bringing a mainstream grey-water recycling system into the home.

Water Legacy's residential graywater reclamation system conserves potable water by recycling spent water for safe usable purposes. Wastewater generated by homes is usually either black water, contaminated to levels that prohibit use, or graywater which can be treated and stored for non-potable reuse.

Water Legacy's system is a stand-alone system that collects used bathing greywater, filters and disinfects this water, and manages the automatic supply to the toilet system. After it's installed, it requires no operator intervention.

Unlike the DIY solutions, Water Legacy uses a multi-barrier disinfection system to ensure that even the water in your toilet has been disinfected using hydrogen peroxide and UV. Unfortunately, this only supplies water to your toilet and is not designed to help you water your lawn or plants.
