| Summary: | Sewage lagoons are used in several communities of the Northwest Territories, Canada to provide low-cost sewage treatment. Information is sparse, particularly during winter, to prove the effectiveness of this method in arctic climates. The objective of this study was to evaluate the performance of lagoons in arctic regions by a study of the lagoon at Inuvik, N.W.T., over a 1 year period.Results of this study endorse the continued use of sewage lagoons as an effective and low-cost sewage treatment method for small arctic communities. In spite of some serious design and construction deficiencies, and several-fold increase in loading, the Inuvik lagoon has provided reasonable treatment at minimal cost over the past 15 years. Its ability to sufficiently reduce bacterial loads to the receiving stream must, however, be seriously questioned. |
