Sewage lagoons: do/can they work efficiently in the Manitoba climate? William H.N Paton

Includes bibliographical references.

Sewage or wastewater lagoons have generally been referred to as oxidation or waste stabilization ponds in the referred scientific literature. So what are wastewater stabilization ponds? Basically they are shallow, large-area lagoons providing long retention periods for the processes of natural purification to act on the introduced wastewater.They may be considered as the bottom of the list of the methods by which man attempts to accelerate the natural processes of purification and stabilization. They are simple, partially controlled systems which do,however, represent a complex interaction of physical and biochemical processes which must be understood in order to be facilitated. There is surprisingly little, beyond making available an adequate area, that the designer can do to control the processes involved and, once created,there is even less that the operator can do to modify or improve the situation (Ellis, 1983; Mara et al., 1992).
