The absence of a water recycling system at the Aus settlement, ||Kharas Region, could cause wastewater from a sewerage treatment plant to pollute the underground water.

Queeny Koopman, who is the Control Administrator at Aus, explained that the sewerage treatment plant has no system in place to recycle waste into drinking water or for other purposes. 

Because of this, Koopman says, the plant discharges wastewater into a nearby dry riverbed, posing a risk of underground water pollution.
