Grey Water Filtration Made Eas(ier)

Behind this beautiful Mediterranean inspired home lies a myriad of green features, sustainable systems and finishes.

One such system feels timely given the scarcity of water we are facing in the west this year.

Drought-stricken California’s homeowners may be thinking about grey water as a means to reuse this precious substance. However, before the advent of the Grey Water system, developed in Australia, called the Nexus system, the main way to use grey water was by diverting water from baths and laundry directly into the yard and onto landscaping.

The system of tubes and tanks filters and disinfects the water with ultraviolet light, employing a unique patent-pending three-stage process that is said to make the water “near potable,” and after being filtered and disinfected, the water is stored in a 200-gallon storage tank. The potential for watering savings is exponential with this device and may cut water use by 1/3 while producing hot water from taps in 3-5 seconds.

How? The system does this by extracting waste heat from grey water via a heat pump, with the heat then transferred to clean water in another storage tank.

This also allows super-fast delivery of water, with hot water available from taps in only 3 to 5 seconds. Not only is this a convenient feature, but the homeowner doesn’t have to turn on the tap and wait for water to get hot — something that can waste a gallon or two.

Every little step we take to conserve water helps with the severe drought we’re facing in the west. ☀️
