The subject of the 11th Gersau Workshop was limited to selected aspects of urban development. Questions of water supply were left aside, for example, to concentrate on "dirty" portions of the cycle. Within the field of urban sanitation, technical questions were deferred in favour of strategic and organisational concerns. While the primary responsibility for urban sanitation lies with local governments, municipal authorities are seldom able to satisfy mounting needs on their own.
