Course overview
Water, sanitation and hygiene teams often hold survey records, facility registers, population estimates and satellite imagery in separate files. Without a defensible spatial model, managers cannot show which communities lack a functioning service, where contamination or flood risks threaten infrastructure, or whether investment choices reach intended populations. Maps that omit denominators, seasonal access, asset condition or data quality can direct scarce drilling, rehabilitation and sanitation budgets to the wrong places. GIS provides a disciplined way to combine these sources, test patterns and communicate operational priorities.
This intermediate course develops the GIS and remote-sensing methods used to plan, monitor and report WASH programmes. Participants structure WASH geodatabases, collect and quality-check field coordinates, map water and sanitation assets, calculate service coverage, assess travel time and identify priority gaps. They apply hydrological screening, satellite-image interpretation, land-cover classification, multi-criteria vulnerability analysis and time-enabled monitoring. The course also addresses cartographic design, dashboard reporting, metadata, access controls and responsible handling of household and protection-sensitive location data.
Teaching combines short technical briefings with guided case work based on water-point inventories, sanitation surveys, settlement data, population grids and satellite imagery. Participants work individually and in groups to build maps, test analytical assumptions, interpret results and prepare decision-ready outputs. Delivery is instructor-led over 10 days, either in a classroom in more than 50 cities or live online, with approximately 6.5 contact hours each day. Participants leave with a completed WASH spatial analysis package, reusable templates and a certificate of completion.
The course is suited to WASH programme staff, GIS practitioners, monitoring specialists, engineers, public-health teams and implementing partners who need to turn field and secondary data into credible location-based decisions.
