This study investigates water storage practices and greywater reuse in unpiped homes in Greenlandic settlements, highlighting the need for improved access to WASH hardware to prevent microbial contamination of water. The research was conducted in two phases: fieldwork in Greenland, and laboratory experiments at DTU in Denmark with a literature study. Fieldwork involved collecting data on household water storage and performing water quality analyses, while laboratory experiments focused on the feasibility of using Biologically Activated Gravity-Driven Membrane (GDM) technology and investigation on Point-of-Use disinfection for greywater recycling. The study found that greywater storage units exhibited high levels of microbial contamination, necessitating treatment before reuse. GDM technology showed potential for treating greywater but requires further research on nutrient-balancing and biofouling. Evaluated disinfection methods included boiling, NaDCC chlorine tablets, and UV-C LEDs, with boiling identified as the most favourable option due to its high water safety, cultural acceptance, and low initial cost. The study emphasizes the importance of addressing water storage practices and exploring robust, locally produced, and scalable greywater recycling technologies to improve water quality and public health in Greenlandic settlements.
