We use our dishwasher but only need to run it every few days and use the Water Miser feature, so it probably uses less water than washing dishes three times a day for several days. But in the summer I do use a lot of water just to maintain my gardens. But I can tell that this is going to be a bad La Nina drought year for us, so I may have to half-starve my plants and shower every third day or something -- yikes!
