KARACHI:
The rehabilitation of Sukkur Barrage will cost the government Rs25 billion, while the cost of construction of a new barrage will be around Rs100 billion according to the irrigation secretary, Zaheer Hyder Shah.
A meeting at CM House was held on Monday to discuss the reconstruction and rehabilitation of Sukkur Barrage.
Shah said that since the barrage was constructed in 1932 sedimentation problems had plagued it. The permanent closure of 10 gates formed an island and a submerged weir, which has reduced the flood capacity of the barrage from 1.5 million to 900,000 cusecs.
The secretary said that all the gates were replaced between 1986 and 1992 and emergency repairs were carried out in 2004 when a large scour hole developed in its right pocket.
He said that all the gates of the barrage are in good condition, except the five, which need to be replaced. Its pond level and freeboard below the gates also need to be increased. This would help open the gates to their maximum level.
The secretary said that the flood of 2010 passed with freeboard margin of just about two feet when the gates were opened completely. During high floods only 27 of the 66 barrage gates remained active, causing risky flow concentration in the central left part of the barrage.
He said that the rehabilitation of the barrage, including the repair of canal head regulators, right pocket river training works, fish-pass and overflow weirs in span 59, dredging works, electrical works, modernisation of monitoring and control instruments, construction of new buildings for monitoring, control system, laboratory, workshops and other buildings will cost Rs25 billion.
"We will hold another meeting to make a concrete decision. Protecting the barrage means protecting the agriculture of Sindh," said the chief minister.
