The City Council approved $100,000 pilot program Tuesday that will be the precursor for a rebate system intended to go into effect next year.Rebates could be in the range of $850, said interim Water Director Andrew Quigley, which, in a far-sighted move, is the amount the city currently rebates for gray-water systems. Rainwater harvesting captures rainwater for use on a property, while gray-water harvesting reuses water from washing machines, sinks, showers and bathtubs for irrigation.
The rebates are not expected to begin until July 2012, because Tucson Water which spent $23,000 setting up a similar gray- water-harvesting rebate program, is now spending $100,000 to set up the rainwater program.
In the United States, a typical water-harvesting system can cost between $2,500 and $4,500, said Lincoln Perino, who installs them in Tucson for Technicians for Sustainability. More
