The province of Punjab has been blessed with immense quantity of fresh groundwater. On the contrary, the quality of groundwater in the province of Sindh is mainly saline. There are very few pockets in Punjab where the quality of groundwater is saline. The commands of Punjnand Abbasia Canal and Fordwah Sadqia Canal, on the let bank of River Sutlej, are one of those pockets, which are underlain with saline water.

In order to mitigate the effects of waterlogging & salinity, it was envisaged to lift the saline groundwater and dispose-off into evaporation ponds under the scheme of Salinity Control & Reclamation Project (SCARP-IV). ECNEC approved the project in 1981 while the construction work started in the following year i.e. 1982.


2. SCARP-IV PROJECT

The World Bank funded project of SCARP-IV has undergone several revisions not yet finalized. The project comprises 514 saline tubewells in Rahin Yar Khan district of Punjab. The disposal of effluent of the tubewells was originally proposed to be thrown, through Manthar and Khanpur drainage system to five different evaporation ponds. The area of five ponds, as calculated by consultants M/S Tiption and Kalm ING and M/S NESPAK ILACO, was 67,000 Acres. The location of proposed ponds was partly in Choolistan desert of Punjab and partly in the desert area of Deh Poh-I and Deh Sutiaro of Taluka Daharki of Sindh (please refer Annexure-I). The area of ponds was calculated in a way to keep balance between the quantity of disposed effluent and evaporation losses. The area of each pond and its location is giving as following...
