Out of the total 159,400 hectares of available land, 120,897 hectares or 83.79% land is used for agriculture. Rewari is deficient in rainfall and has to depend on manual irrigation. Slope of the district, from south to north, is a great hindrance in bringing water from north using gravity flow. To overcome this, work on Jawaharl Lal Nehru (JLN) canal was started in 1974-75 to bring water by successive lifts using high capacity pumps. The JLN feeder is 104 kilometres long channel taking off from tail of Delhi parallel branch at Khubru. Even so, most of the irrigation is still done through tube wells.
