Studenteropgave: Semesterprojekt


In Denmark, we are able to provide ourselves completely with groundwater. In danish households, pure drinking water is used for both toilet flushing and laundry. If we did not have this ability, due to limited water resources, we would probably be forced into using alternative sources, such as rainwater and semi-clean wastewater from sinks and showers - also known as greywater. Recent studies of our groundwater inventory show, that an increasing demand on water supply, along with pollution from human activities, poses a threat to the available amount of drinking water in the years to come. Especially Copenhagen, with its high population density, is facing the exact issue at this point. By using rainwater harvesting- and greywater recycle systems our drinking water can be substituted in toilet cisterns and washing machines. In that way the groundwater resources can be spared. Sustainable use of groundwater resources can be put into practice by using treated greywater from showers for toilet flushing and treated rainwater for laundry. With a sustainable use of our drinking water and secondary water resources, we can ensure the demand of water in the future. This paper examines alternative water sources to be used in apartment buildings in Copenhagen, and compares experiences from other cities outside of Denmark. On this basis, we will try to develop a profitable plant with the purpose to partly provide apartment buildings with secondary water.
