Blue Drop: 97.06/100
✓ Met cited-period drinking-water criteria
The directly cited Blue Drop 2023 record met the drinking-water criteria represented here. It does not establish today's tap-water status.
City of Ekurhuleni in Gauteng has a directly cited DWS Blue Drop score of 97.06/100, with Odyssey tracker tier Excellent. In the 2023 record represented by this tracker, the drinking-water signal is marked as meeting the cited criteria. This is not a live tap-water advisory. An official Green Drop programme anchor is linked for 2022, but Odyssey has not matched a metro-wide numeric score to that primary source. W4 also did not promote the stored numeric score because the 2025 IRIS row-level report was unavailable during the 12 August 2026 check. A legacy 30.9% water-efficiency percentage is retained for audit continuity, but its exact measure basis is not treated as reconciled.

One of Gauteng's strongest drinking water performers at 97.06. ERWAT had six Green Drop certifications in 2022 cycle. DWS opened two Water Act cases against the metro in December 2023, so wastewater is not entirely risk-free. NRW close to international norms by SA standards.
