See where's the best and the worst drinking water in SA

SA's drinking water quality has declined since 2012, with half of sampled municipalities' treatment systems scoring poorly in their effectiveness in removing harmful bacteria, a preliminary report shows.

The Department of Water and Sanitation on Tuesday released a set of reports aimed at improving drinking water quality, wastewater management, as well as water conservation and demand management. The Blue Drop Watch report, in particular, is a technical assessment of drinking water quality based on a sample of 151 (out of 1 035) water treatment systems across different municipalities between December 2022 and February 2023.

The full Blue Drop report, which will be released in July, covers all drinking water supply systems.
