The first step in a typical drinking water treatment process is to screen the raw water to remove large particles such as sticks, leaves, and other debris.

The screened water is then passed through a coagulation basin where chemicals are added to remove small particles. The water is then passed through a sedimentation basin where the particles settle to the bottom and are removed.

The water is then passed through a filtration system to remove any remaining particles. The water is then disinfected to kill any harmful bacteria.
