Laura Allen of Greywater Guerrilas stopped by today to give us the lowdown on recycling greywater and the new draft permitting rules on the table in California to encourage rainwater harvesting and catchment systems. She offered some practical advice on installing residential greywater systems (three-way valve, anyone?) and some background on commercial systems. We'll never look at a toilet or washing machine the same way again.
