Groundwater at the state of Kelantan is fully developed for potable use since 1935. The public water supply in Kelantan is handled by Air Kelantan Sdn. Bhd. (AKSB). The demand on groundwater for potable use has risen steadily over the last 30 years. Presently, fresh groundwater supply is obtained from 82 numbers of production wells located at 13 well-fields at North Kelantan. Groundwater for these all well-fields is drawn from shallow aquifer system except in Tanjung Mas and new wells at Pintu Geng. At present the total groundwater consumption is 134Ml/d, which constitutes about 41% of the total water production in AKSB’s water treatment plants. The demand of groundwater for potable use is estimated to be 165Ml/d in 2010 and will increase at a pace of 2.5% per year.
