Hi! I'm Bob the water drop! I am evaporating from the ocean! Some of my buddies evaporated from plants.
I am a tiny droplet of water vapor in the air. Many others like me, formed this cloud.
When vapor and clouds cools, it falls as a rain, hail or snow.
Rainwater drains into rivers.
Here I go falling into the river...
Rivers flow into the sea...
Flowing to Waterworks
Here I flow from the river into a reservoir to be stored for later use.
At Waterworks, water trickles through beds of clean gravel & sand, or carbon, to remove particles of mud & other solids. After filtering, the water is treated w/chlorine to kill harmful bacteria & then pumped to storage tanks & piped to houses and factories.
Sewage (waste water) is cleaned before it is pumped into the sea. The water is filtered to remove waste & then left in sedimentation tanks for the solid particles to settle. Bacteria decompose any remaining organic mater and break it down into harmless substances.
Houses, factories, & people use treated water. The wastewater is piped to Sewage Works.
