The current drought is expected to continue through this year in our area, and we need to find ways to sustain the lawn and plants at our new house. I'm hoping to find a local company to install a cistern for rainwater collection, but may have to settle for a bunch of rain barrels. In addition, how safe or advisable is it to use the water from the washing machine? Could I divert the greywater for use on shrubs? Are there HE detergents for front load washers that would be okay for the plants? During a previous drought, we kept 5 gal. buckets in each tub/shower and poured that water over the shrubs and flowers; it made a huge difference and we didn't notice any harm from the soap & shampoo. Any advice on how best to do this? Thanks.
