    Almost too simple to be true.

    Let plants and communities of microorganisms, bacteria, algae, fish and snails are working away to purify the community's raw sewage and "gray" water.


    It’s being used all over the world. My question is; is it cost effective?

    In my area Tampa is conducting a potable reuse study. They already are treating waste water "for residents and businesses in parts of Tampa where it can be used to irrigate lawns and landscaping. Tampa's reclaimed water rate is $1.20 for each unit (748 gallons of water) used"

    I have no idea on how expensive it is to go the next step -- from irrigation water to drinking water, but it already seems pretty cheap.
