OK I just read my bill. I have roughly a 2000 SF home with two full baths and a laundry room, I sit on about 1/8 of an acre and have a large front lawn that I water once a day for 15 minutes and planters around the whole property with two people living here and we use on average in June 507 gallons a day. Last year the same time we used 817 gallons a day. I hope this helps a little for what you are looking for. Also I have one sink that constantly drips other than that nothing else leaks. All of my faucets were installed in 97 and I have taken out all of the water saving parts so that I can shower with more than a sprinkle.
