Toelichting


SamSamWater maakt informatie over water en sanitatie beschikbaar en toegankelijk voor iedereen.

Hierom hebben we een database opgezet, die via deze pagina geraadpleegd kan worden. De database bevat allerlei informatie, bijvoorbeeld 'best practices' (bewezen technieken), kaarten, geo-informatie en achtergrondinformatie. De informatie is afkomstig van verschillende bronnen, waaronder onderzoeksinstituten, bedrijven, organisaties en overheidsinstellingen.

Als u informatie heeft die wij in onze database kunnen opnemen, of als u opmerkingen of vragen heeft, dan horen wij dit graag!

N.B. De documenten en beschrijvingen op deze pagina zijn vooralsnog alleen beschikbaar in het Engels. Als u behoefte heeft aan een Nederlandse vertaling dan kunt u rechtsboven op deze pagina op "Overige talen" klikken. Vervolgens kunt u "Nederlands" selecteren in het pull down menu, waarna deze pagina via een automatische vertaling naar het Nederlands vertaald zal worden.
