Main / Items / Water


A clear scentless liquid.

Water is found on Wurm's coasts, lakes, and wherever the terrain drops lower than the constant level of Wurm's water table.


All water tiles are categorized into 6 groups:

  1. Sea - open water
  2. Sea shallows - open water shallower than 25
  3. Lake - enclosed water, larger than a pond
  4. Lake shallows - enclosed water shallower than 25
  5. Pond - enclosed water, not big enough to be a lake
  6. Water - not big enough to be a pond
  • any water tiles underground uses Lake or Pond (or Water)

Lake water is considered fresh, while sea water is considered brackish. Brackish water can be drunk and used for cooking as usual (with no ill effect), and can be boiled to make salt - 1 salt per kilogram of brackish water.

All surface tiles with a corner underwater (i.e. below the water table height) are marked as WATER. There is then a fill process, starting at the map borders, marking any connected WATER tiles as SEA; shallow connected tiles (i.e. less than 25 deep) are marked as SEA_SHALLOWS. Note that a SEA_SHALLOWS tile does not count as a connected tile for the purpose of converting WATER to SEA.

Once all tiles connected to the borders have been handled, any bodies of WATER that contiguously cover at least LAKE_RADIUS tiles in a row (N-S and E-W) are converted to LAKE tiles. Additional WATER tiles next to LAKE tiles are also converted to LAKE (i.e. the LAKE fills adjacent WATER tiles). Any LAKE tiles that are less than 25 deep are marked as LAKE_SHALLOWS, and any SEA_SHALLOWS tiles that are closer to a LAKE tile than a SEA tile are converted to LAKE_SHALLOWS.

For any remaining bodies of WATER tiles, if the body is a contiguous body of POND_RADIUS in a row (N-S and E-W), the tiles are converted to POND, along with any adjacent WATER tiles (i.e. the POND fills its connected tiles). Note that POND_RADIUS is intended to be smaller than LAKE_RADIUS, so a POND is a body of WATER that’s too small to be a LAKE (but still large enough to be a POND).

Any tiles in caves (i.e. underground) with a corner under water is then marked as WATER. Large contiguous bodies of underground WATER are then marked as LAKE or POND, depending on size, in the same way as above-ground LAKE and POND tiles.

At the end of this process, there may still be some WATER tiles - these will be bodies of water too small to be PONDs. Tiles are recalculated at server start.

Notes: Inland body of water surrounded by shallows = LAKE (assuming it’s large enough, POND if it’s too small) Inland LAKE connected to SEA by at least 25 depth canal = SEA Inland LAKE connected to SEA by less than 25 depth canal = LAKE Any tile with water, less than 25 depth = SHALLOW (sea or lake depending on closest water tile) LAKE = 7 radius (N-S, E-W), POND = 2 radius (N-S, E-W) All water in caves is automatically fresh Single tile over 25 deep = WATER, probably won’t get fish in it


Once collected, water is used to:

  • Create food through cooking it together with other ingredients.
  • Bake flour into dough.
  • Drink to regain stamina regeneration (can also be done directly on the tile)
    • Drinking will refill the water bar at the rate of 4.5% for every 0.1 of water volume
  • Mix with other items using alchemy to make dye, lye, etc.
  • Temper metal smithing items
  • Wash cloth items
  • Water pottery items before hardening in a fire
  • Can be used to treat acid wounds similar to healing covers which also turns it into a burn wound

Water Level

Wurm's water table is universally set and is, therefore, always found at the same level.

Water depth puts some restrictions on various actions:

  • Paving: At water level (+/- 0)
  • Passable by large carts: Seven below water level (-7)
  • Tunneling: North-western corner at most 12 dirts below water level (-12)
  • Digging: Up to seven dirts below water level (-7)
  • Surface mining: Up to 25 dirts below water level (-25)
  • Floor mining: Up to twenty five dirts below water level (-25)
  • Dredging: Up to 180 dirt, depending on your digging skill (-180)

Traveling on the Waterways

  • It is possible to swim reasonable distances across water, but if the player's stamina falls too low while in the water, they will start to drown and eventually die. This makes crossing large bodies of water very difficult without a boat or a swimming animal on which to ride.
  • While unladen and unarmoured, a player can swim at about 8km/h.
  • While swimming, players suffer a large combat rating (fighting) penalty, so it's not recommended to fight while doing so.

Additional Notes

  • For a list of possible containers for water and other liquids, see the containers page.
  • Water can also be found at certain fixed locations by using a pendulum to perform divination. Water sources found in this manner must be accessed by placing a fountain or well on the spot.
  • "Rare Water" is a possible item. Its special features are still unknown.
