1. R T w KEY: R=reclamation center T=treatment center W=water tower ___ = dirty/used water ___ = clean water UPSTREAM DOWNSTREAM From “T” To “R”

2. Reclaming/Reusing Water: Water flows downstream (towards the ocean). Houses and businesses have separate pipes leading to/away from them. A water line takes clean water towards the house/business. A sewer line takes the dirty/used water away from the house/business which eventually connects to a water reclamation center. In the reclamation center, the water is cleaned and then released back into the river. The water goes through different cleaning processes before being released back into the river. The water flows through mixers/clumpers, clarifying pools and filters. Prior to being released back into the river, organisms are sterilized through UV light.

3. Downstream, water treatment plants pull water from the river. In a water treatment plant, the water is cleaned again – mixers/clumpers, clarifying pools, and filters. Before the water is released for consumption/use, chemicals are added to the water (chlorine and fluorine – both in the Halogen Family on the periodic table) to kill any remaining organism and make the water safe for use (potable). Water leaves the treatment plant where it is sent to water towers which help store the water and put pressure in the water lines in order to flow through the faucets (against gravity).
