Increased use of reclaimed water could be one of the solutions to Beijing’s growing water shortage, particularly for non-potable (e.g. landscaping) purposes. The ‘Dragon-shaped River’, a large artificial waterscape built on the site of the 2008 Beijing Olympic games, offers a useful case study of the issues and challenges attendant on wastewater reclamation and reuse. Of particular interest is the use of phytoremediation techniques for bioremediation of nutrient loads. This paper presents the results of ongoing monitoring which indicates that phytoremediation is succeeding in preventing eutrophication, though some challenges, notably management of aquatic biomass, remain.
