AUSTIN, Texas -- Residents of a Texas county say they hope a plan to build homes that harvest rain will catch on in other drought-stricken parts of the country.
Travis County commissioners this week approved a developer's plan to build 10 $500,000 homes that rely on rain rather than wells or water piped in from Lake Travis.
The developers of the Vistas at Pedernales Canyon Trail say a family of four should be fine with 12 to 15 inches of rain a year and Travis County usually gets about 30 inches a year, the San Antonio (Texas) American-Statesman reported Thursday.
Rainwater will flow from the roof into cisterns and then run through filters for household needs, the developers said. County officials called it a small step toward resolving looming water issues west of the Texas capital of Austin.
