Things like the pit latrines polluting the groundwater are not always such a big concern - it is usually much better to ensure good excreta disposal i.e. a lot of working pit latrines, even if they pollute the groundwater somewhat.

By the time the groundwater reaches the well (or even borehole) faecal pollution is likely to have been filtered out. Sanitary surveys in Engineering in Emergencies are a good idea for this kind of situation.

Specific guidance might be much more useful - providing solutions to specific problems you observe rather than giving you generic texts. Texts might be good for the rainwater harvesting parts and reservoirs - there are some small earth dam books in the library.

Bio-sand filters - a good resource is https://www.biosandfilter.org/biosandfilter/ which is one of Bushproof's websites.
