The government of Angola will develop a National Plan for Dam Safety to outline a programme for the gradual refurbishment of these facilities, the Angolan minister for Energy and Water announced Thursday in Luanda.
João Baptista Borges said that at the moment the structural behaviour of the majority of existing dams in the country was unknown, because there is no continuous monitoring of their physical state.
The minister also said that various studies of dam disasters showed that foundations and spillways are responsible for about two-thirds of the incidents, and that the behaviour of the dam structures and malfunction of their constituent parts also had to be considered.
On the sidelines of a meeting with national and international experts to collect contributions to the preparation of this plan, the minister pointed out that there were also dams that produce electricity in need of intervention, such as the Biópio dam, as well as others that needed “urgent refurbishment.”
Angola has eight hydroelectric dams, Capanda, Cambambe Biopio, Gove, Matala, Luachimo, Chicapa and Lomaum and twelve for agricultural irrigation, including Calueque Cambumbe, Gandjelas, Quipungo, Chicungo, Chicomba, Calima, Dungo , Luinga, Quiminha, Neves and Sendi. (macauhub/AO)
