There is no resource more precious and more endangered in Southern Arizona than water. Each of us uses an average of 96 gallons of potable water per day.

Faced with uncertainty about how climate change will affect our water resources, Pima County and the City of Tucson recently formed a joint Water and Wastewater Oversight Committee to plan for a sustainable water future.

Producer Laura Markowitz follows the flow of wastewater in Pima County and describes a water-saving alternative to flushing that has been embraced by a neighborhood in Marana.

An Earthship is a radically sustainable home made of recycled materials.

* Electricity is from the sun with solar panels and wind with wind modules.
* Water is caught on the roof from rain and snow melt.
* Sewage is treated on site in interior and external botanical planters.
* Heating and Cooling is from the sun and the earth.
* Food is grown inside and outside.

Earthships are constructed with recycled materials and perform as expected in any part of the world, in any climate and still provide you with what you need to survive.

Earthship Biotecture is a global company, based on 40 years of research and development by Michael Reynolds, principal architect of Earthship Biotecture.
