With the establishment of Sri Lanka Land Reclamation & Development Corporation (SRLRDC) by a parliamentary act in 1968, the drainage division of the Irrigation Department had been closed down. Later in 2002 the drainage division was re-established as the “The drainage and flood protection branch” by understanding the necessity of a separate division to address issues related to salt water intrusion, drainage and flood issues in irrigation and drainage schemes of the country. The name has been changed to “The Drainage and Flood Systems Branch” with the implementation of restructuring of the department considering the functions of the branch. The main objective of the Drainage & Flood Systems branch of the Irrigation Department is to minimize the damages to crops (mainly paddy cultivation) by floods, water stagnation and salt water intrusion in some areas of the country. The second objective of the branch is to protect human lives and all kind of public and private properties due to floods, drainage and salt water intrusion.
