February 13, 1913: Engineering Newsarticle. Sewage Disposal Investigations at Cleveland. By R. Winthrop Pratt. “SYNOPSIS-Preparatory to the design of sewage-treatment works for Cleveland, Ohio, a series of tests is being made of various methods of treating the sewage. The causes leading up to the decision to treat the sewage, and to make the tests before building the proposed works are outlined and then the testing station is described. The station includes grit chambers, screens and tanks for preliminary treatment, rapid filters or scrubbers, sprinkling filter, auxiliary settling tanks, and a disinfection plant for final treatment; tanks for dilution studies; sludge digestion tanks and sludge-drying beds, and an office and laboratory….
On July 25, 1905, the city appointed a commission of experts, consisting of Rudolph Hering, George H. Benzenberg and Desmond FitzGerald to study the general question of improved water-supply and sewerage for the city. This commission, about six months later, submitted a report in which was recommended:
(1) The extension of the water-works tunnel to a point about four miles from the shore.
(2) The construction of an intercepting sewer system to collect the sewage from the entire city and discharge the same into Lake Erie, at a point about 10 miles east of the Cuyahoga River. This intercepting sewer was to be designed to carry twice the dry-weather flow from one million people, on the basis of 200 gal. per capita, or a total of 400 gal. per capita per day. This plan involved several overflows into the lake and river to take care of the discharge in excess of the above amount.
(3) The construction of a river flushing tunnel and pumping equipment for the purpose of pumping clean lake water into the river above all local pollution, was recommended by two members of the commission.”
