How to Easily Reduce Water Use

If you go to the American Water website and log into your account, you'll find under the tab "usage" a link called "usage overview". Click on that and it takes you to a graph like the one below. Click on the "Neighborhood Average Usage" box in the upper right and a green line will appear that compares your water consumption to the local average.

Below is what ours looks like. We use about 2000 gallons per month, which is less than a sixth of the local average. How do we manage this? We're empty nesters for one, but it's mostly a matter of valuing water, and understanding that every time you turn on the tap, you're consuming elaborately treated water that was pumped 20 miles uphill to Princeton, and that every bit of the water that goes down the drain then has to be elaborately and expensively treated at the Stonybrook wastewater treatment plant on River Road. That understanding makes us less cavalier about water use. Some easy strategies for reducing consumption are listed below the graph.

MEANS OF USING LESS WATER

• Resilient native landscaping, and mulch to prevent the soil from drying out
• Get in the habit of turning the water off when washing hands, brushing teeth, i.e. don't let water run straight from faucet to drain. 
• Shorter showers, or even "Navy" showers (turn water off while lathering up)
• low flow toilets (people liked to make fun of them, but they flush better than the inefficient older style); lots of good brands. Ours are American Standards available at the local hardware.
• Get in the habit of using cold water for most tasks, rather than waiting for the hot water to arrive at the faucet. 
• Front load washing machines use a minimum of water
• See below for way to minimize water use when washing dishes.

SAVE ADDITIONAL MONEY

• I once learned that your annual sewer bill is calculated based on your water usage in the winter (likely Jan-March), since they want to charge you only for water that goes down the sewer, not the water you use in summer to irrigate your yard. Therefore, winter is an especially good time to hone your water conservation habits, since it will save you money on your sewer bill year-round. 
• Adjust your water heater (somewhere in your basement) so that it only heats the water slightly beyond the hottest water you need. Many water heaters are needlessly overheating water, which is not only wasteful and expensive, but also leads to lots of fiddling with faucet handles to mix in just the right amount of cold water. Ideally (though no use of fossil fuels is ideal), you should be able to turn the hot water on for a shower--no cold at all--and be comfortable.
• A novel approach to hand-washing dishes: One doesn't need standing water in the sink. Moisten the dishes while stacking them in the sink, to soften the dirt. That way, nature does most of the work. Put some dish soap on a sponge, then with the water turned off, wash some dishes and set them on the counter. Turn water on to rinse that batch, using the rinse water to further moisten the unwashed dishes in the sink. Then turn the water off and wash some more. This way, no time is wasted turning the water on and off to rinse each separate dish. Sounds elaborate, but quickly becomes second nature, and avoids having water running directly from faucet to drain--the ultimate in pointless consumption. Also, try using only cold water. Water that isn't hot enough to kill germs just makes them stronger. Hot water may be needed if there's grease, but otherwise is not essential. Best time to start the habit of using cold water is in the summer, but the habit once established can often continue through the winter.
