The treated-sewage ratio of Sapporo City reached a high level in spite of the fact that the secondary industry of Sapporo is weak and its population is rapidly increasing. This study focuses on these particular characteristics of Sapporo City. Principally, the cynosures of attention were the treated-sewage ratio and the revenue source problem. More specifically this study aimed to: 1) uncover the factors behind the high treated-sewage ratio and 2) clarify the sources of revenue and the financial problems consequent to public sewerage works. Based on the results of the above examination the following points have been elucidated: 1) The bid to hold the 10th and 11th Winter Olympic Games encouraged the setting up of a construction plan as part of an urban environment reconstruction program. Thus, investments in sewerage treatment plant construction were intensively made and the rate of government subsidies greatly increased. 2) The source of construction expenditures was government subsidies and bond issues, but from 1965 to 1972 substantial amounts of city funds were used. As regards financial problems, the burden of city expenditures became heavier because of the rapid increase in loan payments due to greater outstanding bond issues. Moreover, in spite of the fact that the sewerage works of Sapporo City are basically completed an increase in construction expenses has recurred starting in 1986 which has been brought about by the furtherance of flood countermeasures.
