Revision history [back]

I have found this paper: Tap Design Review in Emergency Water Supply – https://www.watersanitationhygiene.org/References/EH_KEY_REFERENCES/WATER/Piped%20Water%20Schemes/Piped%20Water%20Schemes%20General/Tap%20Design%20Review%20Thesis%20(Cranfield%20University%20-%20Gildas%20Le%20Hyaric).pdf It is a bit out of date, but gives a good background to things to look out for and possible sources.
