There are many community organizations in Marin to support you should you choose to convert par of your water usage to grey water. Grey water refers to water that has been reclaimed from laundry, kitchen or garden use and reused for toilet flushing, garden watering and other second tier uses. Sometimes the water is filtered and captured into a holding container of some kind.The water can also flow directly from one source to another as in the case of landscape water usage. (See below for resource list.)
In permaculture the water mantra is Slow it, Spread it, and Sink it.
Before the advent of pavement, roadways and culverts, our rainwater for the most part, percolated back into the soil filling the aquifers, creating humidity and maintaining high rain fall through evaporation of the moisture laden soils. Once we began to pave and cement over our surfaces, water that was once destined for the soil and fish-filled creeks was diverted into singular tributaries which created not only increased run-off, but high velocity run-off. Why does speed matter? Our fisheries require water speeds that the returning salmon and trout can swim against. When you add the pollutants that come with run-off – motor oil, detergent, human waste, fertilizers etc, the water becomes dangerous. Fish can’t repopulate. Ground water does not resaturate. Run-off actually CAUSES drought by removing moisture from soils and thus decreasing evaporation. So what can we do? Create a rain garden! It is fun, beautiful and gives your soil a recharge.
