http://www.statesman.com/news/texas/city-building-17-5-million-line-for-reclaimed-154994.html Wonder if any other cities are doing this, and if so, why can’t HO’s reclaim their “grey” water? It can’t be too hard to isolate potable & non-potable systems, and only use it outside for irrigation. I’ve been doing it for years, but it’s not “legal.”

Well, some of that comes in just how gray the water is, residentially.
Much of the water down the kitchen sink, is more black than gray. And the 'excess" water used likely helps in dilution, too 9just think of cleaning chicken parts or the like).
This gives muni-level treatment plants something a residence cannot, scale. Not that I'm keen to add yet another utility connection in the street, mind you--but it remains an intriguing thought.
Yeah, I know what you mean. Just wondering how long it'll take for Austin Water & Wastewater to get the lines crossed and all of UT comes down with the dysentery. I'll have DW take a canteen every day when she goes to work....
I believe the UPC or current equivalent allows you to split certain greywater from other water and use it to irrigate. I'm thinking it was 'Appendix J', but I may be mistaken.
I designed a greywater storage, treatment, and land application system for a house ... accepted by the State of Idaho but rejected by the local Health District who had a difference of opinion w/ the state. I even designed it after commercial land application systems.
Sometimes the regulating authorities stick their heads in the sand and don't want to hear about or explore opportunities. That seemed to be the case with the Technical Guidance Committee in Idaho whos job it is to explore and consider alternatives. They really weren't doing that about 15 yrs ago; maybe it has changed.

I've worked on the design of several wastewater treatment plants in rural communities where the effluent water is used to irrigate crops. It gets pumped from settling ponds to a series of irrigation pivots.
The City of Los Angeles has a modern sewage treatment plant in the middle of the SF Valley which reclaims a very large percentage of it's effluent for use in irrigation of nearby public golf courses, freeway landscaping and to fill a ten acre concrete pond in an adjacent park. The pond is used for human powered boating. Though not approved for swimming, fishing is allowed.
I work with a wastewater reclaim system as well. Treated sewage water is used for a golf course irrigation ponds/system. This is a fairly common wastewater land application system. Treated wastewater is used for all kinds of irrigation applications including some crops (not necessarily edible crops).
