From the designed full scale excavation area with the maximum amount of water needed to maintain a constant water level in the basin estimated to be 10,000 CMD, water supply was performed for 17 days, 14days was the normal recharge test, the other 3 days was sand added test, an average discharge of water supply was 10,000 CMD. The water level was kept at 1.7m, and average infiltration velocity was 15.2 m/day, after the sand added test, the infiltration velocity was declined from 15.2m/day to 5.3m/day. The clogging is the main factor of the infiltration velocity reducing from the study. Using the soil characteristic curve by the pressure plate to find out fine sediment penetration depth is greater than 35 cm in a gravel filter. The use of grain size filter has been designed a good performance during the operation of groundwater recharge in terms of sediment trap efficiency and maintain the permeability of underlying aquifer.

The clogging is the main factor of the infiltration velocity reducing from the study. Using the soil characteristic curve by the pressure plate to find out fine sediment penetration depth is greater than 35 cm in a gravel filter.
The use of grain size filter has been designed a good performance during the operation of groundwater recharge in terms of sediment trap efficiency and maintain the permeability of underlying aquifer.
