He later oversaw a major expansion of the Fort Worth, Texas, water and sewer systems until returning to school in 1923[3] to earn a Master of Science degree in civil engineering from MIT in 1925.

Graduate students he taught to apply chemistry, bacteriology, advanced mathematics, and hydraulics to investigation of wastewater treatment became prominent in the fields of teaching or engineering practice.

[2] The firm prospered through the housing boom with associated hydraulic and sanitation projects following World War II, and formed overseas offices in the 1960s.

[5] He also served on the National Institutes of Health Research Grants Division Sanitation Study Section from 1946 to 1949, on the United States Public Health Service Advisory Committee for the Revision of the Drinking Water Standards from 1959 to 1962, as chairman of the American Sanitary Engineering Intersociety Board from 1956 to 1962, and as chairman of the Joint Committee for the Advancement of Sanitary Engineering from 1957 to 1958.

While remembered for his advances in the treatment of water and wastewater, Camp was early to emphasize the importance of source control in engineering environmental solutions.
