I did a search, but didn't find a thread specifically answering my queries about water pumps:
1. Is it confirmed that purified water is distributed through the workbench network, and that you can therefore scrap the manual water pumps in "dry" settlements?
2. Does scrapping the water pumps force the settlers to use purified water, thus improving their "happiness"?
3. Is there any negative impact to having a "0" water status in a dry settlement, once you've scrapped the water pumps?
Thx for any (accurate) info!
