ERWAT's Green Drop status

The Department of Water (DWA) launched, in late 2008, a Green Drop certification program for wastewater care works. This initiative is an effort to ensure that they progressively improve their operations so as not to impact negatively on the water bodies into which they discharge their product.

The proposed system aims at awarding water services authorities with Blue and/or Green Drop Status if they comply with drinking water and wastewater legislation and other best practices required by DWA. This incentive-based regulatory approach is a first for South Africa, and is internationally regarded as unique in the drinking water regulatory domain.
