I don't get the intense focus on grey water in these threads. Grandparent poster mixes up grey water and tertiary recycled water down thread, so maybe confusion over that or selective use of terms so Arizona comes out on top? Who knows?

Sure, Arizona seems to be leading in grey water, but treated effluent are exponentially higher flows and that absolutely is being used and applied in Southern California. GWRS is currently operating at 100 MGD of indirect potable reuse and in the midst of an expansion to 130 MGD and San Diego is currently building their indirect potable system to 83 MGD. All in addition to the 100s of MGD tertiary recycled water distributed via purple pipes and other means throughout the region. This is not to say the current status is sufficient(I'd love to see an exponential expansion on managed aquifer recharge), but seeing a number of recent threads opining as if no "responsible" water management is being done in the region, which is frankly, absurd.
