Rainwater is 20 times cleaner than any ground water.

Invest in a sturdy above-ground swimming pool and a tight cover, and collect water off your roof. Google 'texas water harvesting' for more info.

One inch of rain on a 1000 sqft home or garage will collect 600 gallons of water. A 12' diameter pool that is 52" tall and filled to 44" holds about 3,200 gallons of water; 5" of rain will fill it.

If you have a home roofed with asphalt shingles, and a garage with a metal roof, use the metal roof.

Keep your kids out of it.
