From what I gather, a modern automatic dishwasher uses less water than washing the same amount of dishes by hand. This would reduce the wastewater load on the septic system and thus help preserve the drainfield. I do not know the number of gallons saved; would it benefit the system enough to warrant switching to an automatic?
Also, I know that the chemistry of the detergents has changed with modern technology. How friendly are modern detergents to septic systems? In addition to the effects on bacteria etc., I am particularly curious about how fats are broken down in hand washing (Dawn etc.) versus auto washing.
