There are 3 main ways of acquiring Water.

1. Collect Water from the Water Well
Upgrade the Water Well within the Camp and get a certain quantity of Water for every survival day.

Consistently upgrade the level of the Farm to increase the yield.

2. Exploration
Lack of Water can be satisfied through exploration. The farther away the area is, the acquirable quantity of Water increases. The gain amount is tripled for Danger zones.

Food can be found in all areas, but is mostly found at the Riverside, Open Field and Shopping Center.

3. Purchase from the Shop
If acquiring Water from the Water and 'exploration' is insufficient, it can be purchased with Bottle Caps in the Shop.
