MUNICIPAL WASTE-WATER REUSE VIA SOIL AQUIFER TREATMENT FOR NON-POTABLE PURPOSES

Groundwater recharge for wastewater reuse developed and practiced succ essfully in the Dan Region Project is rather a soil aquifer treatmemt (SAT) system which should be considered as an integral part of the mun icipal wastewater treatment process. SAT consists of controlled passag e 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 recover y 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 unres tricted agricultural uses. industrial uses, non-potable municipal uses and recreational uses.
