Most cities treat their wastewater and discharge back to the environment so that the water can be abstracted downstream by others following dilution with the natural flow. Coastal and estuarial cities do not as they are the last to abstract from the river. The missing piece of infrastructure to correct this is a pump station and pipeline to take the treated water back upstream of the abstraction point.

I agree the water crises and limited natural dilution for coastal cities. However, water recycling would be the good option for them rather pumping back to the upstream. Points made by Dr Modak are valid

Sewage is the biggest wastage of water from cities. A few important big cities in the world have started processing sewage into reuse grade water, Singapore being the pioneer. In line with the same, world over the system for water recovery from sewage ought to be made mandatory to support save water cause. Secondly, the water harvesting is another important factor which can augment water cause. The huge buildings have very significant water catching surface area, from where, whatever rainwater can be caught should be accessed. These two factors seem important for water cause.

Namibia - another example for wastewater recycling

Australia has been investing quite hugely in both water recycling and stormwater harvesting projects after the 10 year ling drought during 1997-2007. Demand management has also proven a very successful strategy to minimise the water wastage at household level by bringing down the residential water demand by 40% in Melbourne. I think the answer lies in diversification of water supply sources and supplying fit-for -purpose water for various demands.Regards, Meenakshi Arora
