The 3-part workshop that will address the following:

Part 1
The eight universal principles of water harvesting along with simple
strategies that turn water scarcity into water abundance – and a whole
lot more.

* Examples and details of passive water-harvesting earthworks in the
private and public sector.

* Retrofitting of existing and new construction single family and
multi-family housing

* Landscape along public rights-of-way, off parking lots, in streets
with traffic calming structures.

You will see how these strategies can help reduce water consumption by
30 to 50%, avert flooding, help grow shade trees passively cooling
neighborhood temperatures in summer by 10 degrees, how such
rain-irrigated shade can reduce skin cancer risk in children at public
schools, local food-security and celebration can be enhanced, and how to
integrated water-harvesting with passive and active solar design/water
heating/power. All of this leading to substantial reductions in utility
use, while increase quality of life and health of the environment at the
same time.

Part 2
* Basics of highly efficient, low-cost, legal greywater-harvesting

* Greywater stubouts. ( simple plumbing connections put in during home
construction that allow the homeowner to easily and inexpensively
redirect their greywater to the landscape for passive irrigation of

Such stubouts will very likely be mandated in all new home construction
in Tucson by 2010. In addition, we’ll cover tax credits for such
systems, wise soap/detergent selection, and how to integrate such
systems with rainwater harvesting and sun harvesting systems. These
systems help reduce water consumption by 30 to 50%, and enable
home-scale fruit production without the use of potable water for

Part 3
* Questions and Answers
* Brainstorming session on how we can begin to develop strategies in
our various spheres of influence.

Light lunch will be available
