- Water accounting method can be used as a tool for analyzing and evaluating of water for different uses. The art of water accounting is to classify water balance components into water use categories that reflect the consequences of human interventions in the hydrologic cycles. This study was conducted at Kalibawang Irrigation Syatein which was located at Kulon Progo region. Result showed that gross inflow at Kalibawang Irrigation system during the growing period of 1999/2000 consisted of rainfall 17 % and irrigation water 83 %. The total use of water for any interest or total depletion (TD) is 53.22 %, water use to meet crop need or process depletion (PD) is 24.46 %, water outflow (0) of the system is 25.15 % and the beneficial utilization or the irrigation system efficiency (BU) is 37.74 %. Water productivity per unit of gross inflow (PWGI) is Rp 63.74/m3, water productivity per unit of delivered water supply or irrigated water (PWWd) is Rp 76.75/m3, water productivity per writ of available water (PWAW) is Rp 89.41An3. Key words : component analysis, water accounting, water balance, gross inflow, water depletion, water productivity.
