Intake
The intake screens prevent debris from entering the treatment facility. The screens are located off the bottom of the river to avoid bringing sediments into the treatment plant and below the surface to avoid bringing oils or other floating material into the treatment plant.

Aeration
Aeration process involves bringing air to contact with water to transfer volatile substances from the liquid to the gaseous phase, thus increase the dissolved air in water. It will improve taste and odor and also oxidize iron and manganese.

CoagulationProcess
Chemical coagulants are added to react with the remaining small particles in the water to form particles large enough to settle out. Rapid mixing distributes the coagulant evenly throughout the water. While, flocculation basins gently mix the water with large submerged paddles so smaller particles collide to form large particles called "floc".

Sedimentation
Sedimentation is physical treatment process that utilizes gravity to separated suspended solid from water. Floc settles by gravity to the bottom of a sedimentation basin. Then, clean water spills over to the filters.

Filtration
Filtration removes any remaining particles that carried over after sedimentation. The force of gravity moves the water through filter media usually, sand.

Disinfection
Chlorine adds to prevent bacterial contamination as the treated water flows through the distribution system to customers.

Fluoridation
Addition of fluoride to prevent dental caries and tooth decay
