Rainwater catchment supplies:
Native plants that can be used as lawn:
Carex praegracilis: Meadow Sedge, more runner, turf-forming
Festuca rubra: Red Fescue, the lumpy lawn, requires much more water than above, but easily available in conventional nurseries.
Bouteloua gracilis: Blue gramma grass is also very lumpy, looks like a bluer Bermuda, great for desert/hi-elevation applications.
Books and other resources:
Shawna Dark et al, Historical Wetlands of the San Gabriel River I believe this is the newest link to the above research showing how dewatered the landscape of the San Gabriel River watershed has become in the last 100 years.
You can buy books, plumbing supplies, etc. from this website. Reading the articles on the website is an education in water storage and reuse. The only source of salt-free dish and laundry cleanser that I am aware of, "Oasis Biocompatible."
Ludwig, The New Create an Oasis with Grey Water, Oasis Design
Ludwig, Builder's Grey Water Guide, Oasis Design
Ludwig, Water Storage: Tanks, Cisterns, Aquifers, and Ponds for Domestic Supply, Fire and Emergency Use--Includes How to Make Ferrocement Water Tanks, Oasis Design
Another excellent resource for water use.
