What city has the largest grey water system?



  1. 0 Votes

    Austin (TX) was among of the first major cities to experiment with large-scale grey-water systems, and as such has the longest history of successful grey-water plumbing in the US.

    Los Angeles and Phoenix also have well-established grey-water programs, although these operate on a much more privatized, personal level than Austin’s, which promotes the most state-active grey-water system in the US.
