Engineer Babagana Zanna was the Managing Director of the Chad Basin Development Authority (CBDA) from 1988 to 1995. He was also a senior officer at the Authority when the original idea of the Alau Dam in Borno State was conceptualised. The dam recently had an issue that led to a serious flood which submerged more than half of Maiduguri, the state capital, with devastating impact on lives, public and private buildings. In this exclusive interview, Engr. Zanna said the integrity of the Alau Dam, when it was constructed was not in doubt.
