Threshold / Standard
For each household surveyed, estimate the total volume of the water used per day and ascertain the number of people that household. Add all the daily household use figures and divide by the total number of people belonging to the households in the survey. Alternatively, estimate the total volume of water used per day for each household surveyed, add all the daily household use figures and divide by an estimate of average household size in the population concerned. It is important to try to find out all the sources of water that are being used for drinking, cooking and hygiene, including those that are used at source (e.g. washing clothes at a river). For more rapid assessment, a survey among people at water-collection points could be used, though this may provide biased sample, for instance where surface water sources provide a substantial part of the water used or where some people do not have access to the water-collection points.
