Field study was carried out to assess the effect of automatic inlet and filtration outlet to reduce non-point source discharge and save agricultural irrigationwater from paddy. The comparison of control and treated plots showed that irrigation water was saved up to 58 mm and discharge water was reduced upto 110 mm. The filtration outlet improved the discharge water quality for SS, COD, TN and TP up to 60.1 %, 0.1 %, 4.5 %, and 26.0 %, respectively. Overall, the findings of this study indicated that non-point source pollution discharged from paddy fields where automatic inlet and filtration outlet wereinstalled could be reduced 266.3 kg/ha/yr in SS, 10.3 kg/ha/yr in COD, 1.22 kg/ha/yr in TN, and 0.10 kg/ha/yr in TP, respectively. This clearly showedthat the automatic inlet and filtration outlet are effective management method for saving of agricultural water and protecting water environment.
