1. Make sure your toilet is an ultra-low flush model, which uses only one and a half gallons per flush.
1. If you wash dishes by hand—and that's the best way—don't leave the water running for rinsing. If you have two sinks, fill one with rinse water. If you only have one sink, use a spray device or short blasts instead of letting the water run. Saves 200 to 500 gallons a month.
1. Put a layer of mulch around trees and plants. Chunks of bark, peat moss or gravel slows down evaporation. Saves 750 to 1,500 gallons a month.
