What is SANS 241?
SANS 241 is the South African National Standard for drinking water quality. It defines the minimum requirements for water to be considered safe for human consumption, covering microbiological, chemical, physical, and aesthetic parameters.
Compliance with SANS 241 ensures water supports long-term health, reduces risks of waterborne diseases, and meets rigorous quality, safety, and taste standards. The standard is uniquely South African and is often adopted by countries in the SADC region.
