(c) If answer to (b) above is affirmative, the details thereof?
ANSWER
SYED MURAD ALI SHAH (Chief Minister), Minister for Irrigation:
(a) It is stated that the inauguration of Sukkur Barrage was on 24-10-1923 by Sir George Lloyd Governor of Bombay. The construction work was carried out from 1923 to 1932 and opening ceremony performed on 13th January 1932.
(b) Sukkur Barrage commissioned in 1932, experienced several problems of excessive silting in the right bank canals. Extensive modeling was carried out in 1942 by construction of Right Pocket River Training works which solved the problem of excessive siltation into the canals but resulted in reduction of design discharge from 15 lac cusecs to 9 lac cusecs.
The history of repairs to damages with the passage of time are detailed below:
· 1949 Cracks in upstream pier Plaster below gate Arch, restored with RCC Jacketing.
· 1950 to 1956 Cracks in the soffit of RCC Arches, repaired through guniting/shotcreting.
· 1958 to 1966 re-emergence of racks in RCC Arches.
· 1982 Collapsing of Gate No.31 and its immediate replacement.
· 1986 to 1992 Replacement of all Barrage gates Rehabilitation Project.
· 2004 The real threat to the Barrage during its life of 72 years was the development of a large scour hole in the Right Pocket in2014, damaging a part of the barrage foundation, which was also restored, repaired through FWO.
The increasing floods due to Climate Change effects, specially in the 2010 flood of 1.13 Million cusecs, highlighted the vulnerability of the Barrage. The feasibility study for the project “Rehabilitation and Modernization of Sukkur Barrage” was awarded on 20th October 2011 to the Joint Venture of consultants:-
· Atkins International, UK.
· Associated Consulting Engineers-ACE, Karachi.
· National Development Consultant-NDC, Lahore.
The Scope of works included identification of works to ensure that the Barrage is safe during lows, extreme flows and during flushing operations (including civil repair works, gates and mechanical works, improvement in instrumentation and control and electrical works), reduce excessive sediment entry into canals and update the operation and monitoring of the barrage.
The study is in progress under World Bank.
*4254. MS. HEER SOHO: Will the Minister for Irrigation be pleased to state:-
(a) Is it a fact that 13 gates of Sukkur Barrage are closed;
(b) If answer to (a) above is affirmative, since when along with steps taken by the Government in this regard?
ANSWER
SYED MURAD ALI SHAH (Chief Minister), Minister for Irrigation:
It is apprised that after construction of Sukkur Barrage, within 2 years the sedimentation problems of excessive silt entry into right bank canals were observed and sandy dunes formed in front of head regulators inside right pocket. The Right Bank Canals could not take the design discharge, therefore the model study were carried out at Puna in 1938 to rectify the problem. The River raining works were proposed in the light of model study report and same were completed in 1940-42.
A result of model study 10 gates were closed as per requirement of technical report not 13 gates, from gate no.6 to 14 and gate no.23 was closed permanently, formed an island and construct a submerged weir to direct the excessive silt entry from right pocket. Furthermore, except above 10 gates all 56 gates are working, functioning properly.
