Where are further water sources in Project Zomboid?

Are there any permanent water sources once the water supply is switched off?

So far I have only found one well on the isolated farm far in the north-west.

Solution 1:

I think there is a second well somewhere in the world, but other than wells, there are no permanent water sources.

You can, at carpentry level 3, build rain collector barrels and collect water from them after it rains.

Solution 2:

River

Use "Cabin in the woods" for base and you will not be influenced by water supply switch-off.

Solution 3:

Permanent sources of water are:

1. River/lake - Requires cooking the water.
2. Rainwater - Use rain collectors or pots placed on the ground. Not completely reliable as it requires rain so make sure you collect enough when it does rain.
3. Wells - If you can find one and to help with that you can check this map.
