Way's Elisa can conserve water at home:
1) Keep the water off while brushing her teeth. While brushing her teeth, instead of keeping the water going it's best that she turns the water off. After she is done brushing her teeth, then she can turn the water back on so she can rinse her tooth brush, and her mouth.
2) Take shorter showers. Taking shorter showers is a great way to conserve water. Instead of taking a 20+ minute shower, take a 10-15 minute shower to conserve water.
3) Don't let faucets run without you needing them. So if your not doing dishes, washing your hands, or taking a shower. Remember to keep your faucets off to conserve water.
Those are a few way's Elisa can conserve water at home!
I hope this helps! :)
