Drought & water woes-I

2017 UN World Water Development Report, Wastewater: The Untapped Resource

Most human activities that use water produce wastewater. As the overall demand for water grows, the quantity of wastewater produced and its overall pollution load are continuously increasing worldwide. Although wastewater is a critical component of the water management cycle, water after it has been used is all too often seen as a burden to be disposed of or a nuisance to be ignored.

The results of this neglect are now obvious. The immediate impacts, including the degradation of aquatic ecosystems and waterborne illness from contaminated freshwater supplies, have far-reaching implications on the well-being of communities and peoples’ livelihoods. Continued failure to address wastewater as a major social and environmental problem would compromise other efforts towards achieving the 2030 Agenda for Sustainable Development.

Using wastewater to grow crops can address water scarcity in agriculture

Judicious use of wastewater to grow crops will help solve water scarcity in the agriculture sector. At a time when we need to produce more food to feed an ever-increasing population, wastewater can be used by farmers either directly through irrigation, and indirectly by recharging aquifers.

Why is water management not prioritised for smart cities?

Water management should be at the heart of all smart city planning. While there is a lot of emphasis on transportation and infrastructure development, water management remains limited to treatment of waste water, quality monitoring, and smart metering in the government’s smart cities strategy.

No clear plans have emerged on how smart cities are to be linked with their water catchments to ensure sustainable provision of water. More clarity is also needed on wastewater treatment, both domestic and industrial.

Navigating the Cauvery

A LESSON from the events over the last few months over sharing of Cauvery waters show that one time, prescriptive, top-down solutions — either by the tribunal or the Supreme Court — may not resolve the conflict.
