urban water cycle water supply water reuse
In order to find new approaches to alleviating the water crisis in Beijing, which is caused by, among others, dwindling precipitation and rapid growth of population, and manifests in a rapidly declining groundwater table, this study explores decentralized stormwater harvesting and greywater reuse at household level as a means to reduce groundwater abstraction and water transfer from other regions. Based on a desktop case study, two concepts for combined harvesting and reusing of storm- and greywater are presented. With rough pre-assumptions, calculations show that a saving of 67.8% of tap water consumption can be achieved with the upgrading concept, compared with 5.9% with the simple downgrading concept. The saving with the upgrading concept equals 0.545×109 m3 annual water volume, if 20 million Beijing people apply this approach. Despite numerous prerequisites, such as water treatment technology, space demand, energy and cost, and public acceptance, this paper advocates combining stormwater harvesting and greywater reuse in households with other measures for Beijing’s sustainable water management.
