Tried something new with clean water in settlements and business is BOOMING.
Most profitable settlements in order:
1. Nordhagen Beach
2. Sanctuary
3. Taffington
4. Castle
Depending on how much room you have you can build a ton of purifiers and water will be stored in your workshops. Sell them off for 20-40 caps(depending on your barter level) and you'll bring in A TON of cash.
Next step is to build defenses and walls to protect my resources. Maybe later I'll try to get a monopoly from the kid in diamond city.
This is nordhagen. Still plenty of room to build more just ran out of ceramic
