Do You Know Your Water Footprint?

Water Footprint Calculator

Sometimes it’s difficult to feel connected to water shortage matters in other places, especially when we’re on opposite coasts of the country or half a world away. But while it may seem like the issue is too big, or too far, and our everyday actions as individuals barely make a drop in the bucket, that’s simply not true!

Earlier this week, GRACE Communications Foundation launched a brand-new online footprint calculator that is focused on household water consumption. The interactive questionnaire uses data from the Water Footprint Network, the U.S. Geological Survey, the U.S. Energy Information Administration, the U.S. Environmental Protection Agency and several other sources to calculate an individual’s water footprint. It takes into account the indoor/outdoor water usage we’re all familiar with, like doing the laundry and washing the car.

Your water footprintIt also calculates virtual water consumption: how much it takes to make the food we eat and the products we purchase. From take-out food to clothing, tech devices and home furniture, all the stuff we buy takes a lot of water to make. Did you know that the average water footprint of an individual in the United States is 2,200 gallons a day?

So take 10-15 minutes of your day to calculate your footprint, or better yet, get the entire household involved! Learn about greywater systems and low flow faucets with your family. Change your answers and see the difference it makes, down to the gallon. You can use it as an educational activity with children (check out our kids section here).

The water footprint calculator is useful in re-evaluating daily habits, and in light of the water shortage issues in the past few years, can also be a reminder of each of our roles in water conservation, no matter where we live. So we can always be mindful consumers of our planet’s resources!

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 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!
