rural area, source separation, sustainable sanitation, vacuum toilet, water saving, zero emission A sustainable sanitation concept will be realized at a visitors centre in the national park JASMUND on the isle of Rügen, Germany. Main idea of the zero-emission concept is source separation of faeces. Blackwater will be collected by vacuum toilets and reused via biogas plant and agriculture. Greywater will be treated on-site by reed bed technology and recycled for toilet flushing and watering. Rainwater will be throttled on-site and infiltrate in a nearby forest. In comparison to conventional wastewater management (3km duct to public sewer or decentralized treatment of unseparated wastewater) cost reduction of 25 percent are estimated
