Water Treatment Process

Safe & Palatable for Consumption

The Water Plant processes river and well water to make it safe as well as palatable for consumption by the citizens of Aberdeen.


Treatment begins as the water is pumped to the first process. The water is first pumped to the pretreatment area where, utilizing a rapid settling system, the blending of sand and polymer grabs particles that contribute to taste and odor in the finished water and removes them from the water. Potassium permanganate can be added to aid in the removal of odor-causing organisms and materials.


Carbon is added after this to continue to improve the taste. Lime and soda ash softening and clarification take place after which carbon dioxide must be added to return the pH to an acceptable level. A corrosion inhibitor and sometimes a polymer are added before the water travels to the filters where the remaining particles are removed.

Disinfection & Fluoride

The water is then disinfected and fluoridated and finally sent into town for your consumption.
