"The report provides a general approach to deciding the \"\" where, when, and how much \"\" in developing and implementing wastewater management interventions. Its scope covers two main considerations: 1) the need to incorporate the general principles that determine water resources management policies into the design and selection of wastewater management and pollution control interventions; and 2) the need to address water quality problems at the appropriate geographical scale, normally at the river basin level. The report looks at the experience of four higher-income countries (France, Germany, Spain, and the United States) in managing wastewater at the river basin level." .
