Is ageing Kariba Dam Wall doomed? Sifelani Tsiko The Interview A new study by the United Nations University Institute for Water, Environment and Health warns that ageing dams pose a growing threat to public safety due to the potential for dam failures, over topping or leaks. Kariba Dam, a 128-metre-tall dam which stores 180 cubic kilometres of water straddling Zimbabwe and Zambia on the Zambezi River is cited as an example in the report. In this report, our Agriculture, Environment & Innovations Editor  Sifelani Tsiko (ST) speaks to the Zambezi River Authority chief executive Engineer  Mun...

Water Warning: The Looming Threat of the World’s Aging Dams Tens of thousands of large dams across the globe are reaching the end of their expected lifespans, leading to a dramatic rise in failures and collapses, a new UN study finds. These deteriorating structures pose a serious threat to hundreds of millions of people living downstream. Who would want to live downstream of the 125-year-old Mullaperiyar Dam, nestled in a seismic zone of the Western Ghats mountains in India? The 176-foot-high relic of British imperial engineering cracked during minor earthquakes in 1979 and 2011. According ...

NEW YORK: Over a thousand large dams in India will be roughly 50 years old in 2025 and such aging structures across the world pose a growing threat, according to a UN report which notes that by 2050, most people on Earth will live downstream of tens of thousands of dams built in the 20th century. The report, titled 'Ageing water infrastructure: An emerging global risk' and compiled by United Nations University's Canadian-based Institute for Water, Environment and Health, says most of the 58,700 large dams worldwide were constructed between 1930 and 1970 with a design life of 50 to 100 years....

Copy to Clipboard (Getty Images) Aging dams are an emerging risk, according to scientists. They project that most people globally will live downstream of large dams by 2050, which were built in the 20th century and many of them are already operating at or beyond their design life, say scientists. In the US, for example, over 85% of the dams (over 90,000 of all sizes) in 2020 were operating at or beyond their life expectancy. Dam failure risks the lives of people living downstream, and aging dams should be investigated to assess the threat, recommend investigators.  Water storage infrastructu...

The report, "Ageing water infrastructure: An emerging global risk," by UNU's Canadian-based Institute for Water, Environment and Health, 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."
