The Multibarrier Approach to Safe Drinking Water

Can you ensure Miguel's family has safe drinking water?

In this module, learn about preventative and treatment barriers to drinking water contamination. The multi-barrier approach combines several barriers to ensure that water is free of pathogens and safe to drink.

Discover the basics of the six barriers:

  • Source Water Protection
  • Safe Water Transportation
  • Sedimentation
  • Filtration
  • Disinfection
  • Safe Storage and Handling.

This module is part of a series on Household Water Treatment and Safe Storage. In this series, you can learn how to choose and implement a combination of methods, technologies and barriers to achieve safe drinking water in homes, schools, and clinics.
