Clean Water for All of Liberia

With the help of Sawyer filters, Liberia will be the first developing country with clean water, border to border, in every household by December of 2020. Sawyer filters will bring clean water to the last 20% of rural Liberia that everyone said was impossible to reach. THE STUDY: Independent, U.S.-based scientific research teams from Calvin College are collecting and processing data from GIS (geographic information system) software. Currently, they are tracking the implementation of 100,000 Sawyer filters placed throughout Liberia. The results will be submitted for peer review and scientific publication in the American Journal of Tropical Medicine and Hygiene.

The use of Sawyer Water Filters was able to reduce diarrhea by over 90%.

Measurements include:

  • Diarrhea reduction
  • Work and school days recaptured associated with waterborne sickness
  • Purchased water savings and medical savings associated with waterborne sickness

In the first 23,719 households analyzed, 34% reported cases of diarrhea. After a two-week follow up, the number was down to 2.95%. A second follow up at eight weeks reported another decrease. The use of Sawyer Water Filters was able to reduce diarrhea by over 90%.
