The man who started it all Dr. W.D. Hatfield was an innovator in
wastewater treatment technologies and analytical methodology.
He served as Superintendant of the
Sanitary District of Decatur from 1 924 - 1 958. He also served as the President of
the Central States Sewage Works Association and the Water Environment
Federation.
Numerous organizations annually present a “William D. Hatfield” award for
outstanding performance and professionalism in wastewater treatment.
