    Sammanfattning : Utanför Uppsalas stadskärna planeras det att bygga en ny stadsdel till år 2050, kallad Sydöstra staden. Uppsala kommun vill vara i framkant gällande hållbar stadsplanering och är därför intresserade av att utreda möjligheter till att tillvarata resurser i avloppsvattnet, som ett alternativ till konventionell rening.
