A friend had a tank in the attic over her garage. I am not quite sure what the details were. The rainwater fed into it with an overflow that went into a tight line drain to the stormwater system. She had it attached to soaker hoses in the beds around the house. This way she could adjust the sprinklers for the lawn so they didn't hit and stain the house stucco and still have nice shrubs and flowers around the house. I think she had some sort of valve to switch them over to city water during a dry spell. memory fails.
