The City of Tucson Goes Gray
On September 23, 2008 I was touring the Upper Santa Cruz River with Amy McCoy of the Sonoran Institute as my watershed tour guide. The trip was awesome; I never knew that the southeast corner of Arizona was so beautiful.
Towards the end of our day trip Amy was anxious to get back to Tucson to attend an important City Council meeting, I didn’t know it until later that it was the vote on the Grey Water Ordinance that Amy was trying to make it to. The Sonoran Institute, using EPA Targeted Watershed Grant funds, helped to put together the ordinances for the City Council vote.
Because there’s so little surface water in the Tucson area, the city’s major water source has always been groundwater. The Grey Water Ordinance is aimed at reducing the use of scarce drinking water to irrigate desert landscapes. The city estimates that 45 percent of water use is for landscaping, and using rainwater and gray water would greatly reduce this.
The ordinance requires rainwater harvesting plans and capturing systems for any new commercial building built after June 1, 2010. The Ordinance requires that new homes built after that date be plumbed for gray water irrigation systems. This means having a drain for sinks, showers, bathtubs, and washing machines separate from drains for all other plumbing, to allow for future installation of a gray water system.
A key factor contributing to the success of this ordinance was the involvement from the entire community, from plumbers and landscapers to the Friends of the Santa Cruz River, they all added their support for the ordinances success. In addition to the community support, an EPA grant helped finance some of the work towards creating the ordinance language.
The City of Tucson was selected for a Pacific Southwest Regional Environmental Award and on the day of the awards ceremony, I had no idea who was coming to accept the award, but had heard that Councilman Rodney Glassman was coming. He was the driving force behind the ordinances, but I had no idea what he looked like. Well, Rodney is about 6’8”, and super energetic, really hard to miss. Once we connected it was great to sit and chat with him, he is very passionate about the ordinances, Tucson, and Arizona. Way to go Councilman Rodney Glassman and the City of Tucson!
