The Sacramento Bee (probably my all-time favorite newspaper name) has run a couple articles lately about rainwater harvesting. Columnist Dan Weintraub is the latest to weigh in on the subject. The previous article is here.
Rainwater harvesting, like greywater systems, is the kind of conservation that cities have to encourage through zoning laws. Big, expensive projects like advanced water recycling plants, certainly have their place, and, of course, can be built by big agencies with big ribbon-cutting ceremonies. But individual scale recycling is the more powerful solution, not least because of the large-scale change in attitudes and practices it would require.
