I have been reading about various water projects, and some of them are not working in the most sustainable way. i.e. installing plumbing! Please watch this video about water retention landscaping, and how it has been done in a community in Tamera, Portugal. It is so important.
It is totally natural, and brings entire ecosystems to life.

Put your fears up in the sky and let them be changed by the clouds. Let them be cleansed by the rain.
