Ellis Sylvester Chesbrough (1813–1886) was an engineer credited with the design of the Chicago sewer system, which are sometimes known as the 'Chesbrough sewers'. This was the first comprehensive sewer system in the United States. He is responsible for the plan to raise Chicago, construction of the first water crib in Chicago, and designing the Boston water distribution system. The water system he designed for Chicago is on the National Register of Historic Places and has been designated a Historical Civil Engineering Landmark by the American Society of Civil Engineers.
