Evaluation of impact of Khushab sub surface pipe drainage project in Pakistan

Abstract

This paper describes the essential contents of research at a recently completed subsurface pipe drainage project located in the Khushab district of Pakistan. The paper explores the need and decision by Government of Pakistan to install a Sub Surface Pipe Drainage Project near Khushab where an old Surface Drainage System was already installed by the Provincial Irrigation and Power Department, Government of Punjab, Pakistan, since 1960. The new Sub Surface Pipe Drainage Project’s planning and executing agency M/S Euro-Consultant used existing Surface Drains with remodeling for to carry the additional drainage effluent of newly constructed sump pumps of the pipe drainage system connected to the old drains by means of small outfall drains. Until now the new system is working well in lowering the water table as well as increasing the agro-socio-economic status of the local population.
