An Expansion Program for the Anderson Sewage-Treatment Works

There are a few things about Anderson that I feel I must tell you in order to justify the planned expansion program for our sewagetreatment works. In 1938, under the Federal Emergency Adminis­ tration of Public Works, Project No. 1225 F was started and in June, 1940, the treatment plant was placed in operation. The plant has a designed capacity of 8 m.g.d., using the Guggenheim biochemical proc­ ess, which is a patented process licensed to the City of Anderson by the Guggenheim Brothers. At the time this plant was placed in operation, Anderson had a population according to the U. S. Bureau of Census of 41,572. The plant was designed for a detention time of two hours for primary set­ tling, 1.8 hours for aeration, and 2.3 hours for final clarifying, which is, as you all well know, a very short detention time to accomplish the reduction in suspended solids and B.O.D. generally required. How­ ever, the plant is capable of giving a good percentage of reduction at the designed capacity and has been doing a fairly good job at over­ loads considerably in excess of the designed capacity.
