My dad was setting up local factories for similar pots in several nations in Africa 20 years ago. They sourced local clay and sawdust and provided plans for clay presses. There was a fund that provided the starting capital and the silver solution. The same fund also provided plans and technical help with the construction of locally built rope-pumps. These technologies were used in tandem to provide relatively easy (drinking) water to remote communities.
The most amazing effect was that women from these villages would save a lot of time everyday and used that time for some little side hussling and village life really improved.
It's one thing when there's no infrastructure or easily accessible source of water. It's another when you're in Arizona next to the Colorado River. The thought of people in the first world having to get their potable water from a treated pot for purely political reasons is why it's absurd.
