Revision history [back]

David's answer is excellent.

The only thing I would add is that, from WaterAid's survey of previous boreholes and pumps installed, and seeing that a large proportion of them don't work after just a few years, we can quite confidently say that water points managed by communities alone have a high probability of failing, unless there is external support from authorities / water regulators / water providers. It is a bit more detailed in our sustainability framework.

It shouldn't discourage you from promoting better water supply, but please consider technical issues and community issues as highlighted by David, and how it fits in public plans and support.

Good luck,
