Act now — no map needed

The interactive map needs JavaScript to shade live conditions for your country. You don’t need it to act — these vetted, globally relevant organisations are one click away.

Cut your own water use this week · opens en.wikipedia.org → Most household water leaks through old toilets, faucets and irrigation. Fixing them is one of the fastest, cheapest things any individual can do.
Map a public drinking-water tap on OpenStreetMap · opens openstreetmap.org → OpenStreetMap is the public dataset our map already uses. Adding a single tap, well, or fountain near you helps everyone who comes after.
Map for humanitarian response from your laptop · opens tasks.hotosm.org → Humanitarian OpenStreetMap Team (HOT) trains anyone, anywhere, to remotely trace buildings and roads in disaster-affected places. Aid agencies use the result the same day.
Send funds to a vetted WASH organisation · opens wateraid.org → These are independent, internationally audited groups working on safe water and sanitation. Pick one — small recurring gifts beat one-off big ones.
Report bad water near you · opens who.int → If water at home, in school, or in a public place looks, smells, or tastes wrong — tell the people whose job it is to fix it. Citizen reports are how outbreaks get found.

Water-Quality Map

Tap any place — see current water-quality conditions and the open-source treatment techniques that fit. Country shading from WHO/UNICEF (drinking-water access) and FAO (freshwater stress); disaster alerts from GDACS; water-quality readings from USGS gauges. All refreshed once a day.

Opens on a top-5 worst region for the active indicator. Use search or the worst-list to explore your own region.

Live water disasters

Floods, droughts, and tropical cyclones from GDACS (UN OCHA + JRC). Click any event for recommended actions. Recent (<7 d) events are highlighted on the map.

Each technique is community- or household-scale and pairs with at least one freely accessible reference (CAWST, Eawag/Sandec, SSWM, WHO, EPA, IRC…). Click any card for details.

How this portal works

Country shading shows live data fetched per visit:
- Drinking-water access gap — WHO/UNICEF JMP via Our World in Data.
- Freshwater-withdrawal stress — FAO AQUASTAT (UN SDG 6.4.2) via Our World in Data.
Click anywhere to see techniques. The recommender derives need signals (drinking-water gap, water stress, disaster proximity, climate band) and ranks the catalog by use-case match plus simplicity.
Live disasters come from GDACS (UN OCHA + JRC). The popup ranks the techniques most likely to be useful for that disaster type. Use the time-window chips to focus on the last 7 / 30 / 90 days; recent (<7 d) markers render larger.
US gauges (USGS) show every USGS NWIS site that reported temperature, pH, dissolved oxygen, specific conductance, or turbidity in the last hour. Green = all readings in expected range, yellow = one out-of-range, red = two or more. Click any gauge for the latest values and a deep link to the official USGS site page.
Freshness. The three feeds above (indicators, disasters, USGS) are pulled on a daily schedule, normalized into a single tiny payload, and served to every visitor. The browser only ever talks to our own server for them. Result: same-day freshness, one upstream call per day regardless of audience size, deliberately negligible running costs, and a polite footprint on the public agencies whose data we re-share.
Drinking-water taps (OSM) is an opt-in layer. Toggle it on (or click Reload taps in view) to query OpenStreetMap for public taps in the current map view. Cached in your browser for 24 h.
Your pins live in your browser’s local storage. Use Export JSON to back them up or share with someone you trust.
No accounts. No tracking. No upload. Outbound calls from the browser: our own server (live data), OpenFreeMap (basemap), and OpenStreetMap (only if you opt in to taps).

National figures hide local realities. Switching to local crisis data requires sub-national surveys; where a country publishes one, drill down there — the EU’s WISE Drinking Water Reports, the UK’s Drinking Water Inspectorate, India’s Jal Jeevan Mission, the US’s EPA ECHO Drinking Water Dashboard, and equivalent national portals. For places without one, ask local authorities. See methodology.
