Check out your local co-op, buy in bulk.
Oh I know you’ve heard of this one from me before. I buy most of my groceries in bulk. It stores well, it’s cheaper, and it’s saves me the headache of grocery shopping. Check around for a local co-op in your area where you can buy foods in bulk.
Put a brick in your toilet tank.
Adding something heavy into your toilet tank will reduce the amount of water it has to fill up with when you flush. Instead of putting a brick directly into your tank (which can dissolve and possibly create drainage issues), here’s what you can do. Grab a plastic jug (1/2 gallon milk or something similar) and fill it partially with pebbles, sand, or whatever stones you have handy. Fill it the rest of the way with water. Place the container into the toilet tank and replace the lid. This should save you 1/2 gallon of water with each flush. And since the average America flushes the toilet 5 times each day, each person in your family will save an average of 75 gallons of water per month.
Do timed showers.
When I was growing up I can’t tell you how many times my parents yelled at me that I was taking way too long in the shower. Now that I’m an adult I can understand the fact that it not only wastes water that you have to pay for, it wastes electricity to heat up all the warm you are using. As far as electricity goes (based on an electric hot water heater) 30 showers a month at 5 minutes each will cost $10.06 vs 30 showers a month at 10 minutes each would cost $20.11 each month. And as far as water goes, a 5 minute shower will use 12.5 gallons of water vs a 10 minute shower which will use 25 gallons.
