EDITORIAL

The theme of this year's celebration of World Water Day is "Waste Water"and the Campaign is "Why Waste Water".

Target set in Sustainable Development Goal (SDC) requires that by 2030, the proportion of untreated waste water should be halved and there should be substantial increase in recycling and safe reuse of waste water globally. Global demand for water is expected to grow by 50% by 2030 and most this demand shall be in cities. Consequently, quantity of waste water generated and its overall pollution load shall be increasing globally. But waste water management is grossly undervalued as a potentially affordable and sustainable souce of water, energy, nutrients and other recoverable materials. In fact, reused waste water from cities could address challenges like food production and industrial development. Through industrial symbiosis waste water can be used within business itself or between several businesses, as on an average, industrial water consumption is responsible for 22% of global water use. Agriculture in many countries is a potential source of environmental pollution due to use of chemical, fertilizers and pesticides. Improved waste water management can improve the health of workers by reducing risk of pathogen exposure. It may also create direct and indirect jobs in water dependent sectors. As such waste water could be seen not as a burden to be disposal of, but as a potential resources as its reuse after suitable treatment can provide economic and financial benefit.

This issue of the journal contains 8 assorted articles. Other usual features like "IPHE News", "Our Members", "Notes and News" have also been incorporated in this issue.
