Water quality
03 September 2026
We are committed to providing quality water to Cape Town’s water users, and we regularly check the City’s water quality through a system of water sampling and analysis.
Water quality table
Our weekly checks of water samples allow us to measure our compliance with SANS 241 water quality requirements. Our water compliance has consistently exceeded our own internal targets.
The table below shows the percentage compliance achieved for Cape Town’s drinking water:
