FYI for those that hand wash thinking they are saving water.
http://1greengeneration.elementsintime.com/?p=314http://www.landtechnik.uni-bonn.de/ifl_research/ht_1/homeenergy_0504_dishwashing.pdfMy wife normally does the dishes but she has been injured so I have been on duty, and 40 minutes into it I realized (again) we should have a dish washer. So, I set out to the web to prove what I had been told that using a dish washer is actually more efficient than doing it by hand. Above are my findings. (More efficient for us meant less water consumption, and also that means less energy running our hot water heater (gas), but slightly more to have an electric machine wash.) In the end we will save TONS of water, propane, and spend maybe more in electrical to run it, I haven't compared electrical but I do know our overhead lighting in the kitchen uses 450 watts total so it may be a wash since I won't be in there

I am a "super hand washer" because a day ago I pre-cleaned everything, and today I cleaned everything. I haven't measured my sink but I would guess it's more than 4 gallons and I've gone through it 3 times today + rinsing and the pre-wash... well over 5x an energy star dishwasher I`m sure.
Our biggest issue is not putting tons of water and food into the septic, so even with a dish washer we will scrape into the trash our leftovers.
Those of you on septic and with a dish washer how many times a week do you wash your dishes in the machine?
