Table 1.
Overview of assumptions used in calculating DALYs averted, adapted from Table 7.6, Guidelines for Drinking-water Quality, 4th Edition [24].
Table 2.
Probabilistic model output with estimated mean DALYs averted per 100,000 persons pear year as a function of pre-treatment water quality; treatment effectiveness against bacteria, viruses, and protozoa; and adherence.
Figure 1.
DALYs averted per 100,000 population, per year, based on assumptions about technology effectiveness (2 log10 reduction in each pathogen class), adherence, and background water quality assumptions from Table 2.
Table 3.
Sensitivity analysis across a range of pre-treatment microbial counts of reference pathogens and adherence, at “high” and “low” effectiveness (6 log10 and 2 log10, respectively) and at 2 levels of water consumption (1 litre per person per day and 5 litres per person per day).
