As a result of this migration and in part due to the public works moratoria imposed during the war, a major pro- gram of sewer construction was instigated, which resulted in the collection and subsequent concentration of large volumes of waste- water at single discharge points. As the assimilative capacity of these receiving waters was exceeded, it led to or aggravated existing water pollution problems in these waters. To mitigate this degradation of water quality a massive program to construct wastewater treatment facilities was instigated. In addition, large amounts of money were spent on research to improve the technology of the conventional collection and treatment concept. In contrast, the wastewater disposal problem of the rural home owner received little attention, and in most cases the septic tank soil absorption system (ST-SAS) was the interim solution. In recent years there has been a fundamental change in the population growth pattern in the US and Scandinavian countries.
