Scope of work

Die Stadt Winterthur erneuert ihren generellen Entwässerungsplan (GEP). Der letzte GEP stammt aus dem Jahr 2004 und wurde weitgehend umgesetzt. Auslöser für die Aktualisierung sind neue Anforderungen und Zielsetzungen sowie geplante Neuanschlüsse weiterer Gemeinden an die ARA. In diesem Zusammenhang sollen einerseits bestehende Plangrundlagen fortgeführt und aktualisiert werden, während andererseits bestimmte Themen vollständig neu erarbeitet werden müssen.
