Changing showerheads and faucet aerators can cut water use almost invisibly, and for San Antonio Water System customers, it doesn't have to cost anything. Check out these freebies, available at SAWS service centers:
Wash fresh produce in a tub of water. Save the water and use it on your plants.
If you drop ice cubes when filling your glass, don't throw them in the sink; add them to your water-reclamation bucket or spread them around a houseplant.
Collect water from boiling eggs, pasta or potatoes to use in the garden. Let it cool, but don't let it stand for more than a few hours.
Keep a spray bottle of water handy for rinsing your hands while cooking.
In the bathroom
Keep a bucket in the shower and tub to catch water while you're waiting for water to get hot. Use this water to flush toilets or water plants.
Scoop as much bathwater as you can before draining the tub. Use it on plants.
Around the house
When you clean your fish tank, use the water, which is rich in nitrogen and phosphorus, to water and feed your plants.
