What do South Africa's water assessments show?

DWS released the 2025 Green Drop full assessment alongside Blue Drop and No Drop progress assessments on 31 March 2026. The national progress results cover the 2023/24 municipal financial year. The 28 tracked profiles below retain historical mixed-source values; programme labels are only treated as directly sourced where the row citation actually matches that DWS programme.

Row-level provenance audit: 10/28 direct Blue Drop rows. Green Drop: 0 direct and 2 official programme anchors. No Drop: 5 direct programme rows, including 3 rows with a directly typed score/loss/NRW metric. Official anchors do not certify an unreconciled numeric row value; mixed/supplementary rows remain pending.

Green Drop W4 · 2026-08-12: the official DWS release verified the national 2025 cycle, but the IRIS row-level report was unavailable during this check. 0 of 7 stored legacy Green Drop numeric rows were promoted to direct-primary evidence.

What can you do?

Check your municipality

Contact your municipality or DWS for the latest test results and any current boil-water or do-not-consume advisories before treating a historical assessment as today's tap status.

Check the current local advisory

Report unsafe water

If your tap water smells unusual, is discoloured, or you experience illness after drinking it, report it to DWS at ws.dws.gov.za or call 0800 200 200.

DWS hotline: 0800 200 200

Access official data

DWS publishes Blue Drop, Green Drop and No Drop programme results through its official IRIS portal. Assessment scope and reporting year differ by programme.

Data source: National context reflects the 2025 Green Drop full assessment and the Blue Drop / No Drop progress assessments released on 31 March 2026, while tracked entity rows retain their own cited source periods. Regulatory assessments describe the cited assessment period and are not live tap-water advisories. Follow current DWS or municipal advisories for immediate health guidance.
