During the past decade aerated lagoons have become a popular means of economically treating industrial and municipal wastes. Adoption of the Water Quality Act in 1965, and public opposition to water pollution have forced municipalities and industrial establishments to provide adequate treatment for their waste discharges. Aerated lagoons, when used as preliminary treatment ahead of the stabilization pond system, can provide an adequate and economical means of waste treatment. The rural community of Volga, South Dakota selected an aerated lagoon system to expand its existing stabilizat1on pond treatment system. Volga, South Dakota lies in the east central portion of the state and had a population of lOJO in 1970. A major portion of the municipal waste water flow is derived from a ·milk drying plant owned by Land-O-Lakes Creameries Incorporated, Minneapolis, Minnesota. The plant produces dried milk and butter oil. In August,1972, the plant switched to 24-hour operation and was processing between 182,000 and 596,000 pounds of milk per day during the investigations reported herein. The stabilization pond system, consisting of three 7-acre cells was constructed in 1960, about one mile east of Volga near the Big Sioux River. A short time after it was put into operation, this stabilization pond system became overloaded resulting in the production of offensive odors and poor effluent quality. In 1967, the original system was expanded to meet South Dakota effluent standards, control odor problems, and alleviate problems caused by an undersized pumping station and outfall line. The new facilities consisted of a new outfall line and two aerated lagoons which preceded the stabilization ponds.
