Some words that I left at the MapComplete Telegram Group:

Several years ago, there are some mappers start a drinking water map in Taiwan. These mappers are planing to change the map subject, using the code of the drinking water map to deploy more theme map to promote OpenStreetMap. But unfortunately we couldn’t get the resource to make it possible to get plenty of theme maps to get Taiwanese people interested.

Glad to see you guys got supported from OpenStreetMap Foundation, Open Knowledge Belgium, Trage Wegen, OSGeo Belgium, Humanitarian OpenStreetMap Team, Missing Maps.

Some background information about the Drinking Water Map: 1, 2.
