Intermittent Slow Sand Filters for Household Use - A Field Study in Haiti

The effectiveness of the BSF in removing E. coli and decreasing turbidity was evaluated for 107 filters which had been in use for an average of 2.5 years (range 1 to 5 years). The sustained use and user satisfaction were assessed through interviews in each of the 107 households. Durability of the filter, maintenance requirements, and affordability were appraised by recording specific observations during the visits.
