Grey Water Harvesting

The Dirty Water Underground - New York Times

Jamie Kripke for The New York Times

LAURA ALLEN’S modest gray house in the Oakland flatlands would give a building inspector nightmares. Jerry-built pipes protrude at odd angles from the back and sides of the nearly century-old house, running into a cascading series of bathtubs filled with gravel and cattails.

Not only did Volkswagen achieve this milestone in 1999, but they had an even larger goal in mind: an ultra fuel-efficient car with a super stingy fuel consumption rating of just 1 litre per 100 kilometres (282 mpg)."
