Groundwater recharge for wastewater reuse developed and practiced successfully in the Dan Region Project is rather a soil aquifer treatmemt (SAT) system which should be considered as an integral part of the municipal wastewater treatment process.

SAT consists of controlled passage of effluent through the unsaturated zone and the aquifer, mainly for purification purposes. The recharge operation is carried out by means of spreading basins which are surrounded by adequately spaced recovery wells which permit segregation of the recharge zone from the rest of the aquifer.

A very high quality of reclaimed water is obtained after SAT which is suitable for a variety of non-potable uses such as unrestricted agricultural uses, industrial uses, non-potable municipal uses and recreational uses.
