# of individuals reached through WASH services
The quantity of people who directly participate in or receive water, sanitation, or hygiene services through Save the Children or supported partners. "Water, sanitation, or hygiene services" can include but is not limited to:
- Improved drinking water
- Improved sanitation facilities
- WASH NFIs
- Menstrual hygiene NFIs
- Training on any WASH topics
Calculation: Sum all people who received water, sanitation, or hygiene services from Save the Children or its supported partners. Double counting of individuals who participate across multiple activities should be avoided. If you do not know the exact number of individuals who participated in multiple activities, you should reduce the total using your best estimated based on historical data and/or knowledge of where there were overlapping services in the same community.
Data Collection Method/Tool: Program output trackers or IMPACT; aggregated by CO/response team
Data Source: Activity Records, Gov / OCHA Population & Admin Records
Who Collects: Save the Children / Implementing Partner Personnel
From Whom: Recipients of Assistance or Key Informants who can provide reach figures
Frequency of Collection: Weekly / Monthly
Frequency of Reporting: Aligned with donor reporting dates / Bi-annually
How to Count/Aggregate Value: The reporting is incremental. In some cases, you may simply sum the values across all reporting periods. In other cases, you may want to only count unique values, eliminating any duplicate participants that may have participated (and been counted) across multiple time periods.
