Background Information

Bunyala Irrigation Scheme was started in 1959 with an initial 534 acres under paddy rice production. It has been under production since then. Irrigation water is pumped form River Nzoia and flows by gravity through open earth channel to the farms. Due to increased demand for rice, two new pumps sets were installed in 2005 and two more were also installed in 2007. This brought the combined discharge to 1.2m3/s. With the widening of the main canal, the Scheme acreage was expanded to over 1,600 acres on the left bank of the river.

On the right bank of the river, two pump sets (with a capacity of 0.15m3/s each) were also installed in 2007 hence commanding an additional 250 acres at Ruambwa/Mudembi. Currently, the Scheme irrigates 1,880 acres with 1,394 farming households.
