Alum and other chemicals are added to the water to form floe that is sticky and attracts the dirt into larger clumps. When they get heavy, they sink to the bottom during sedimentation. Sedimentation: The heavy particles settle to the bottom and the clear water at the top moves on to filtration. Filtration: The water goes through filters, often made of sand, gravel and charcoal that will catch even smaller particles that float in the water. Disinfection: A small amount of chlorine is added to kill any bacteria or tiny organisms that may be in the water. Storage: Water is stored in a closed tank (tower) or reservoir so the disinfection can take place. It then goes through pipes and into your home or school. ------- PMAERTSBGT XOBF LAKEHR WTLIDJOQTE PAXLLLEWLA INTTUGVPUT PFOEYTDWCM EVSRRAI MKE STRZBNPOYN NEFASKWANT Find and circle these words: STREAM FILTER PIPES SAFE WATER WELL TREATMENT TANK POLLUTION LAKE ------- the ------- the its the to by the the water treatment plant start ------- or the Water is stored underground between rocks, sand, and clay in an aquifer!
