Punjab advocates telemetry system to solve water disputes

Amjad Mahmood
March 31, 2022

Punjab has suggested immediate installation of the telemetry system on Indus basin irrigation system as a permanent solution to end water disputes between provinces, while a private water resource management body pleads for a barrage close to the Sindh border to manage complaints of water theft by Punjab.

Punjab Irrigation Minister Mohsin Leghari suggested at a dialogue on inter-province water disputes held here on Wednesday that the permanent solution to put an end to the argument between Punjab and Sindh as well as Sindh and Balochistan on water share was the telemetry system.

The water gauging system, he said, must be installed as early as possible so that the inter-province bickering causing bad blood among the people is curbed and to deal with the water shortage problem.

The minister also called for adopting advanced irrigation methods to increase the water productivity and building new reservoirs, particularly Kalabagh Dam, as it requires the shortest time – six to seven years – for its construction. He argued that India had built 5,202 large dams since 1947, whereas Pakistan had constructed only two as per the Central Water Commission data.

Advocating the need for promoting cultivation of drought-tolerant but more productive value crops, Mr Leghari also supported the three-tier approach for distribution of water among the provinces to meet their irrigation needs.

Sulaimaan Ahmad of Sindh Tas Water Council suggested construction of a barrage at Kot Mithan, Rajanpur district, in Punjab on the Indus river to curb water theft complaints of Sindh province and Punjab’s grievances that Sindh does not allow water availability measurement at Guddu barrage.

He said water from the proposed site could reach Guddu barrage in Sindh within six hours, while it takes six days even during summers from Chashma Barrage in Mianwali district. Sindh complains that water is stolen downstream Chashma through tubewells, he said.

He proposed that even Kachhi canal should be fed from the proposed Kot Mithan barrage so that Balochistan’s complaints against Sindh for not supplying its due share of water from Guddu barrage were also settled.

Punjab University Vice-Chancellor Dr Niaz Ahmad Akhtar, Punjab Planning & Development member Dr M Abid Bodla and others also spoke.

Meanwhile, Mr Leghari chaired a meeting of the Punjab Water Resource Commission which discussed rules for appointment of water undertakers for better management and conservation of subsoil water resources.

The meeting also approved rules and regulations for implementation of the Water Act 2019. It was attended by Agriculture Minister Syed Hussain Jahanian Gardezi, Industries Minister Mian Aslam Iqbal, Chief Secretary Kamran Afzal, Additional Chief Secretary Ali Murtaza, Irrigation Secretary Saif Anjum, Water Resources Regulatory Authority DG Amer Khan, technical member Arif Anwar, Qadeer Baig and officials of relevant departments.

Instead of the Kalabagh dam, there should be a dam built on the Soan River. The Kalabagh dam as designed would only be able to store 6.1 MAF and would be able to control a flood like was seen in 2010. While the Soan Dam could hold up to 38.4 MAF and not disturb distribution any water from the Indus. It would also have the potential to generate 18000 GWH of electricity.

All of these claims per the Pakistan flood control system.

Can you confirm it is on the same location as listed in the following 2011 proposal/presentation to WAPDA, which I posted earlier in the thread? It’s under the name “Pakistan Flood Control System”.

ISLAMABAD: The Asian Development Bank has suggested to Pakistan that holistic governance across sectors is required to address the growing competition for water and to manage the effects of pollution, wastewater, floods, droughts and land degradation at present and in the future.

Appropriate policies must be put in place to promote integrated management and development, ADB says in a case study on the completion of the new Khanki Barrage project, which it termed as a ‘driver of change’ replacing an old barrage with advanced technology vastly improved water and flood control, connectivity and access to essential social services, ADB says.

The case study, released this week, says projects, such as the New Khanki Barrage that have proven to be successful can serve as models to guide development partners in designing future irrigation projects.

Future irrigation projects will also need to be informed by solutions to water-related problems in several sectors, particularly agriculture. To make infrastructure investments more inclusive, complementary investments in areas, such as education, finance and health will need to be promoted, and are in line with ADB’s multi-sector approach to ensure that interventions systematically address the key multidimensional features of food security..

An irrigation department study had indicated a very high chance that a major flood could damage the Khanki Headworks and breach its embankments, causing significant loss of lives and damage to property, including crops and livestock.

Realising the danger, the Punjab government decided to replace the Khanki Headworks with a new barrage to ensure safe passage of a 100-year-return flood event, sustainable delivery of irrigation water in the command area, and the safety of people and livestock.

Climate change considerations also influenced the decision as the 2020 Global Climate Risk Index ranked Pakistan fifth among the countries most affected by climate change.

ADB provided $270 million loan to Pakistan for the construction of new Khanki Barrage on River Chenab at 275m downstream of the old Khanki Headworks.

LAHORE: Maximum flow in rivers is likely to touch 300,000 cusecs by 20th of May which is already improving day by day with increase in temperature in the country, said sources from Pakistan Meteorological Department (PMD).

According to the sources from the flood department of PMD, total flow has already improved to 190,000 cusecs at present which was around 100,000 cusecs about a week earlier. They said the temperature is likely to stay above 40 degree Celsius in the coming weeks which would be helpful in improving water flows in rivers.

They said both Mangla and Tarbela dams are touching dead levels over the last two months as the total water flow in rivers has reduced to 88,000 cusecs at present. At that time, the presence of clouds in the Northern areas had slowed down the process of snow melting and a hydrological drought was imminent due to non-availability of water in dams. This situation has also inflicted negative impact on the cotton growing areas in Sindh.

The sources further said no heavy rain is expected on 15th of May when fresh spell of westerly waves would enter the country. They said the upcoming spell of westerly waves would bring clouds but still there is no chance of heavy rain. Accordingly, they said, snowpack would keep melting with rise in temperature until the start of monsoon.

It may be noted that the province of Sindh is facing severe shortage of water and Minister for Climate Change Sherry Rehman has claimed that the Indus River is 60 percent short of water. It is also worth noting that that the snowpack in the upper parts of the country has shrunk by 10,000 square kilometer in terms of covered area this year.
 
.,.,.,
The country’s largest reservoir Tarbela dam is likely to touch its dead level next week due to 21pc decline at rim station inflows which will drastically reduce the water supply to provinces.

In a letter to provincial secretaries of Irrigation Departments of all the provinces, Indus River System Authority (IRSA) has informed that the rim station inflows have declined substantially from 206,109 cusecs on May 15, 2022 to 162,082 cusecs which will affect the water share of the provinces.

“I am to state that the perusal of today’s water situation reveals that temperature in the catchments are fluctuating and a substantial decline is recorded at Skardu, which is 21°C against yesterday’s temperature of 27.8 °C,” said the letter written by IRSA Director Khalid Idrees Rana.

Due to inconsistency in temperatures, the rim station inflows have substantially declined by 44,027 cusecs (-21pc) from 206,109 cusecs on May 15, 2022 to 162,082 cusecs May 20, 2022.

It is also very pertinent to mention that the storage component available in Tarbela, Chashma and Mangla is only 0.344 MAF (Last Year 0.995 MAF; 10-Year Avg.. 3.195 MAF), which is not sufficient to augment the dropping river inflows at rim stations
 
Hub Dam balochistan / Sindh
July 17,2022:

Hub Dam today filled to maximum level of 339.15 feet with water storage of 6,87,000 acre feet; sufficient to release water for Karachi and Balochistan for next three years.

Safe passage of additional water through spillways is in operation; Water Resources Ministry, WAPDA and Project Management have been closely monitoring the Dam’s operation vis inflows and outflows.
 
,.,.,
Construction work on multipurpose Mohmand Dam Hydropower Project has been carrying out day and night. Resultantly, the project is moving ahead with a good pace and WAPDA is confident to complete the project during high flow season in 2025 as per the timelines.

It will store about 1.2 million acre feet (MAF) of water, generate 800 megawatt (MW), contribute 2.86 billion units of low-cost hydel electricity annually to the National Grid and help mitigate floods in Peshawar, Charsadda and Naushera.

Besides supplementing 160,000 acres of existing land, about 16,700 acres of new land will also be irrigated because of Mohmand Dam. In addition, 300 million gallons water per day will also be provided to Peshawar for drinking purpose. Annual benefits of the project have been estimated at Rs. 51.6 billion.
