In Tucson, the sight of rain is pretty common at this time of the year, and much of it usually makes its way into a wash.

In the harvesting process, rainwater drips down into two collection points and collects in a cistern. Then, that water can be used to do a variety of things, such as watering plants.

There are a few issues that need to be figured out before rainwater harvesting is made a requirement. Some sticking points are that harvested rainwater would have to supply a minimum of 75% of a development?EUR??,,????'???s landscape water budget. And then, there?EUR??,,????'???s the matter of cisterns. According to landscaper Richard Underwood, ?EUR??,,????'??Cisterns are not real attractive, they look like mini-silos.?EUR??,,????'?? Also, some cost about $2,000 to install.

City Council won?EUR??,,????'???t vote on the ordinance until October. If it passes, the plan wouldn?EUR??,,????'???t go into effect until June of 2010.
