There are several companies selling plastic, food grade water tanks up to 10,000 gallons. You set it up to capture rain from your roof. Add a pump and some plumbing and you are on your way to thumbing your nose at high water bills and the corporate thieves who would take your water and could care less if you die!

There are “gallons” of info on the INTERNET. “Rainwater harvesting is an ancient technique enjoying a revival in popularity due to the inherent quality of rainwater and interest in reducing consumption of treated water,” according to the Texas Rainwater Manual at http://www.twdb.state.tx.us/publications/reports/RainwaterHarvestingManual_3rdedition.pdf. I also have a link to one of the biggest dealers of Plastic Water Tanks in the USA, located right here in Burnett Texas AND they don’t have any tanks Made in China. The link is on railroadingbastrop.com.
Rainwater is sodium-free, important for persons on low-sodium diets. (Your doctor’s going to love this)
Rainwater is superior for landscape irrigation.
Rainwater harvesting reduces flow to storm water drains and also reduces non-point source pollution.
Rainwater harvesting helps utilities reduce the summer demand peak and delay expansion of existing water treatment plants.
Rainwater harvesting reduces consumers’ utility bills. (Bastrop Water Company won’t like that – but does anyone really drink Bastrop’s water?)

Quoting the above BA article: “If the biggest pump wins, rural areas are sure to lose.” Guess what? You don’t have to lose if you start collecting pure rain water. You WILL lose if you wait for your local elected officials to do anything that would benefit rural residents at the expense of their corporate pals.
