5.2 The Source Water

Possible water sources for the scheme were excess volumes from the Berg River during the winter season and secondary treated wastewater. Prior to injection/infiltration, modeling and/or testing was conducted on blending of waters to determine whether any mineral precipitates were likely to form. Source water from wastewater requires additional tests for organic compounds and pharmaceuticals, known to occur in the area. Because the water composition of the source water may vary significantly from time to time, regular monitoring would be necessary. It would also be necessary to evaluate whether water/rock interaction alters the water composition of the infiltrated/injected water within the aquifer and whether the abstracted water would require treatment.
