 We've got to deal with water usage. I can save gallons a day in toilet flushes. That starts to add up pretty quickly. And so I've seen people out there change out those old toilets and go to a one-gallon flush, and you can save a couple hundred bucks a year on water if you have high water rates. Now, it could be $50 a year if you've got lower water rates, but it sure adds up pretty quickly.
