Hello Diwakar
We apologise for the delayed response – we forwarded on your query to our community partner on Tue but haven’t heard back (they must be busy). So that your team can progress with your designs, please assume that there are 4 springs for each aldeia (sub-village), total 16.
All of the springs we observed when we were in Loidahar looked very similar to the one shown in the 360 interactives.
Unfortunately you won’t be able to find much (if any) information on these springs but perhaps you’ll be able to research and find related information on springs in rural Timor-Leste to help inform your design assumptions.
