Water availability has become an important driver for facilitating economic growth in the state of Karnataka. As only 20% of water supplied is consumed and the balance 80% is wastewater, treatment and reuse of this wastewater will reduce the pressure to augment water supply from freshwater sources.

It is fitting that the United Nations Habitat III conference in October will be held in Quito, Ecuador. In April, the city and nearby Portoviejo and Manta suffered an earthquake that killed more than 660 people and injured at least 10,000. Around 73,000 people were displaced. Some 700,000 needed emergency assistance, such as drinking water, sanitation and hygiene kits. Many water-supply systems and hospitals were destroyed or disrupted. Insurance companies estimated the damage at US$2.5 billion, of which only 16% was insured.

Many of the world’s megacities depend on groundwater from geologically complex aquifers that are over-exploited and threatened by contamination. Here, using the example of Dhaka, Bangladesh, we illustrate how interactions between aquifer heterogeneity and groundwater exploitation jeopardize groundwater resources regionally. Groundwater pumping in Dhaka has caused large-scale drawdown that extends into outlying areas where arsenic-contaminated shallow groundwater is pervasive and has potential to migrate downward.

Cities are under pressure from all angles; some pressures are easily forecasted while others are more difficult to predict. Balancing the immediate needs of today without compromising the demands of tomorrow is at the heart of sustainability, and of this report.

Water security in Asia and Pacific has progressed overall in the past 5 years, but major challenges remain, including overexploited groundwater, demand from rising populations, and climate variability, according to the new report from the Asian Development Bank (ADB).

In a bid to streamline water supply in low pressure areas, the Delhi Jal Board has prepared an action plan to replace old pipelines with hydraulic modelling system.

Multiple Agencies, Depleting Water Tables Major Hurdles

This paper raises important questions concerning access to piped water services, especially for the poor. As such, it could have ramifications for how communities and countries reach the water supply objectives of Sustainable Development Goal 6 and the 2030 Agenda.

Despite tall claims of the government to provide adequate potable water to residents, several areas in nine districts of the state have been facing shortage of water.

Already forced to use extra purifying agents for its depleting reserves in dams, the civic body may soon have to resort to the dead stock in Khadakwasla
