This weekend my mother in law Connie and I attended a workshop on rainwater harvesting at Manzanita Village, a co-housing community here in town. Supercool! We ate really good food and shoveled LOTS of dirt. We learned about tanks for holding water as well as basins and berms that you make with dirt to hold water.
We received books written by Brad Lancaster from Tucson and the workshop was taught by Andy Millison.
