We just stopped at a nice restaurant in San Luis Obispo, which is attached to an inn. The management posted an announcement in the restrooms that they were operating an experimental wastewater system by means of which their graywater from dishwashers and sinks was routed through a filtration and purifying system and then used to flush the toilets throughout the restaurant and hotel. It saved them millions of gallons a year. One small local innovation.

Made me proud!
