Data Story : Ageing Water Storage Infrastructure

  • Published
    16th Feb, 2022

The report, “Ageing Water Infrastructure: An Emerging Global Risk”, by the Canada-based UNU Institute for Water, Environment and Health (UNU-INWEH), says most of the 58,700 large dams worldwide were constructed between 1930 and 1970 with a design life of 50 to 100 years, adding that at 50 years a large concrete dam “would most probably begin to express signs of aging.”

Ageing signs include increasing cases of dam failures, progressively increasing costs of dam repair and maintenance, increasing reservoir sedimentation, and loss of a dam’s functionality and effectiveness.

The report aims to attract global attention to the creeping issue of ageing water storage infrastructure and stimulate international efforts to deal with this emerging, rising water risk.

This data story aims to show a comprehensive image of the ageing water storage infrastructure globally and in India.
