More bad news about the drought. Government monitors say the portion of the U.S. affected by extreme drought has risen since last week. The drought is forcing many communities to rethink their relationship with water, and there may be some lessons from cities that are used to living with water shortages.
From member station KUT, Mose Buchele has this story about San Antonio, Texas.
(SOUNDBITE OF CHILDREN PLAYING)
MOSE BUCHELE, BYLINE: I'm standing in San Antonio's Brackenridge Park along the San Antonio River. It's 100 degrees outside but, hey, this is Texas, and there are kids playing and families picnicking. I just asked a guy feeding ducks along the river where the water started, where the source of the river was, and he pointed me in the direction of some natural springs upstream. In fact, that's not completely right. Actually, at this time of year, the water really starts flowing here.
(SOUNDBITE OF MACHINERY)
BUCHELE: This is the place in the park where the city pumps treated wastewater into the river to keep it flowing when the weather is dry. That might sound a little bit gross, but it doesn't stop Ashley Castillo and her husband from fishing here on the river.
ASHLEY CASTILLO: It doesn't bother me too much me.
BUCHELE: So do you eat the fish you catch here?
CASTILLO: No, not at all.
BUCHELE: And aggressive water recycling is just one reason why San Antonio bills itself as Water's Most Resourceful City.
CHUCK AHRENS: It would be asking a lot to remember all of our programs because we have a lot of them.
BUCHELE: That's Chuck Ahrens, VP of Water Resources and Conservation with the San Antonio Water System. His list includes big money projects like desalination. But the city's greatest success is found in simple conservation.
AHRENS: We have an ordinance that doesn't allow you to water after 10:00 in the morning and before 8:00.
BUCHELE: That's to curb evaporation.
AHRENS: We've given out - free - over a quarter of a million water-efficient toilets.
BUCHELE: That, of course, cuts back on water use. The city also offers free audits to show homeowners where they can save water. These are the things that have allowed San Antonio to be one of the fastest growing cities in the country, while not increasing water consumption. In fact, the city still uses about the same amount of water it did in the early '90s, even though it's added more than 300,000 residents.
Calvin Finch heads Texas A&M's Water Conservation and Technology Center.
CALVIN FINCH: Other cities have the advantage that they can see that San Antonio has managed water conservation. And we are still growing.
BUCHELE: But exporting that expertise can be dicey. A few years ago, Water System Director Robert Puente went to Atlanta when it was facing serious drought.
ROBERT PUENTE: And so I and our chief financial officer went out there and gave some talks and made some presentations. They were, I would say, well-received, but they did leave scratching their head. They didn't necessarily understand or agree with what we were doing over here in Texas.
BUCHELE: Puente says his entire business model - to convince customers to buy less of his product - seems backwards in parts of the country where drought is uncommon. In San Antonio, the more water you use, the more you pay per gallon. Currently, only about half of water utilities across the country do that.
Again, Calvin Finch.
FINCH: There's a number of communities that still reward extra water use. You know, just like if you buy in volume, you get a discount.
BUCHELE: San Antonio also funds conservation programs. But Puente points out all that investment pays off when water shortages hit. And it can make for some fun family fishing .

ADDIE CASTILLO: Look at - we catch a fish right now.
BUCHELE: Back in Brackenridge Park, Ashley Castillo's husband, Miguel, has hooked a fish and delighted his daughter, Addie.
MIGUEL CASTILLO: Ah, it's a little perch, that's all it is.
CASTILLO: It's a little baby perch.
BUCHELE: It's also something that wouldn't be possible during drought, if not for decades of serious planning and investment in water resources.
