This may seem like a crazy question, as I have researched this and have found no available information. Maybe someone here can help...
I'm in Arizona (land of water drought) and I would like to put a small lawn in my backyard. However, I want to be very conscientious about the amount of water that I use. Rather than do away with the lawn entirely, or go to synthetics, I would like to find a way to reduce the amount of water that a lawn typically consumes.
My question is this: Can I put a plastic liner in the soil underneath a natural lawn in order to retain (or slow) the loss of irrigation water?
While some of a lawn's irrigation water is lost to evaporation, I suspect most is lost to the soil and water table below. Would a solid, or even perforated liner of some sort help to reduce this water consumption?
thanks for any help you can provide
