IRSA to cut water supply to provinces from December 25 

Disruption due to the annual canal maintenance and de-silting

ISLAMABAD: Electricity load shedding might increase amid chilling weather as the Indus River System Authority (IRSA) has decided in consultation with the provinces to reduce water supply for annual maintenance and de-silting of the canals to be started from December 25.

A spokesman of IRSA informed on Friday that water releases have been reduced from Tarbela and Mangla Dams with immediate effect due to annual canal closure. He said Tarbela outflows reduced to 8000 Cusecs from 18000 Cusecs. Similarly, Mangla outflow reduced to 10000 Cusecs from 15000 Cusecs and will further reduce to 5000 Cusecs from December 25, 2017. He also said that Sindh has reduced its indent to 10,000 Cusecs from 20,000 Cusecs from December 25, 2017, while Punjab indent reduced to 25000 Cusecs from 40,000 Cusecs immediately and Balochistan reduced to 2500 Cusecs from 5000 Cusecs. Also, Khyber Pakhtunkhwa will draw same 3000 Cusecs.

Sources in power sector said that the annual canal closure programme will reduce the output of hydropower units of Tarbela and Mangla by more than 2,000 MW, resulting in increased load shedding amid extreme winter across the country. They also said that though a campaign is launched every year for the maintenance and de-silting of canals by the provincial irrigation departments, however, it has been observed that nominal repair and de-silting is done by the department as water losses other than theft go unchecked for a long time. Local farmers and landlords from the command areas of a canal should be made bound or motivated to play role in the canal maintenance and de-silting work because without their participation, it is not done properly, they added.

Official sources informed Pakistan Today that IRSA has notified the annual canal closure plan, under which canals would remain closed from December 26, 2017, to January 30, 2018, for maintenance and de-silting. They said that the Mangla command canals would be closed from December 26 till January 30 stage wise and Tarbela command canals would remain closed from December 31, 2017, to January 30, 2018. According to the water discharge plan, the authority will release 10,000 to 12,000 cusecs of water from Tarbela Dam and 8,000 cusecs from Mangla Dam to meet drinking water requirements, they added.

Under the canal closure programme, Punjab’s lower Jhelum, Rasul Qadirabad Link, Upper Chenab canal will remain closed from December 26 to January 12, while Qadirabad Baloki Link, Jhang Branch, central Bari Doab canals from December 27 to January 13 and Lower Bari Doab, Baloki, Sulemanki Link from December 29 to January 15.
