Greywater reuse towards augmentation of freshwater demand in high rise buildings

Water crisis is a universal phenomenon now, though its severity varies from place to place. This has led to the substitution of the freshwater by alternate sources. Considering the ease of treatment and round the year supply of Greywater, it is one of the most promising alternatives. Therefore, in this paper an attempt has been made to present a case study for reuse of treated Greywater to encourage planners and researchers for optimal utilization of available resources. Paper suggests that though the probability of microbial contaminants in Greywater is low, however its presence must not only be investigated but should also the risk associated with it in reuse should be eliminated in planning reuse. In addition to this, paper gives a series of steps to popularize the reuse of Greywater in India. The authors understand the public sentiments associated with GW and thus advices to improve social acceptance of treated Greywater through awareness.
