A Tucson, Ariz., city advisory
committee is pushing for all new homes to be outfitted with plumbing systems
capable of delivering greywater from bathrooms, laundries and kitchens to
outdoor landscaping.
According to
theArizona Daily Star, the committee also wants the Tucson
City Council to require developers of shopping centers and other commercial
projects to harvest rainwater for at least 75 percent of what is used for trees,
grass and shrubs.
These proposed
ordinances, which would take effect in June 2010, are likely the first of their
kind in the United States. “They see them as ways to increase water
conservation as population grows and pressure increases on the region's limited
water supplies,” theStarreports.
Critics cite
costs and development discouragement, and the fact that the new ordinance would
ignore a much larger number of existing homes.
