Water Treatment Facts: WATER & WASTEWATER TREATMENT PLANTS (COMMUNITY)

Steps to Water Treatment 1. 2. 3. 4. 5. Coagulation Sedimentation Filtration Disinfection Storage

1. Coagulation n Removal of dirt and other large particles that are found in the water. n Aluminum and other chemicals are added in order to form “floc” (tiny sticky particles) which attract dirt particles.

2. Sedimentation n The heavy particles (floc) settle to the bottom. n The clear water on top is moved to filtration.

3. Filtration n Water is passed through different filtration products to help remove smaller particles that are still in the water. n Such as layers of: n Sand n Gravel n Charcoal

4. Disinfection n A small amount of chlorine or some other disinfection is added to the water to kill any microorganisims that may be in the water. n More recently, some treatment plants have started using UV radiation to purify water.

5. Storage n Water is placed in a closed tank or reservoir in order for disinfection to take place. n The water then flows through pipes to homes and businesses in the community.

Water Treatment Facts: WELL & SEPTIC SYSTEMS (PERSONAL)

Septic System n n Pipe from House: Pipe that takes all the wastewater from the house to the septic tank. Septic Tank: Holds wastewater long enough to allow solids to settle and oils to float the surface. Solid materials will decompose over time. Drainfield: When wastewater enters the septic tank, the same amount of water exits into the drainfield. Soil: Water percolates into the soil and is

Well n n Casing: A tube in the ground that prevents the hole from collapsing and contains the pump and pipes to allow water to come to the surface. Screen: Is attached to the bottom of the well to prevent sand gravel from entering the well. Pump: Brings water up the hole and pushes it to the house. Pressure Tank: Is located in the home. It stores water and distributes it throughout the house
