Less than 20 per cent of the wastewater discharged by households, and 60 per cent of industrial wastewater, is treated in India. This situation has to change, say SHISHAM PRIYADARSHINI and AMISH SHROFF.
We have suggested a series of recommendations based on the basic principles of ecology-based river management of the Ganga. The implementation and follow-up has to be done by the Central government in collaboration with the State governments. Our grand vision is as follows:
Rishabh Sethi, Chief Operating Officer, SPML Infra Limited, shares his views on the huge scope of growth in the country for water recycling and purification of drinking water, and his companyÂ´s upcoming projects in this space.
In order to secure future water needs, the government will have to play a major role, both functionally and financially. Technologies focus on the techno-ecoÂnomic mix for fulfilment of viability requireÂments and also technical requireÂments for specified re-use specified for industrial and domestic sector. Uniform standards are adoÂpted for water quality parameters for the specified re-use to enable the client/contractor to choose the optiÂmum technology at a rational cost.
Zero liquid discharge plants minimise the consumption of freshwater and by the reuse of wastewater it helps relieve freshwater availability limitations in places where it is scarce or expensive. Ganesh Pangarkar explains the technology and process. Power production has an impact on the environment. Besides the fuel gas, other emissions leave the power production process, noteworthy among which is water loss in the water/steam cycle.
Several investors have exited the rural infra segment over the past few years. because they could not achieve the scale they wanted to, perhaps because of wrong strategies. This year, can it be the switch that the government can use to trigger economic growth back on track?
