|For all water pump variants, see water pump.|
The water pump generates three units of purified water for its settlement. Pump production rates are much lower than the water purifiers or powered water pump, but they require no power, need fewer crafting components to build, and unlike purifiers, don't need to be placed in a body of freestanding water. They can be placed almost anywhere dirt is found, including in a garden plot.
Similar to water purifiers, should the water production exceed the settlement's demand, a proportion of any excess water will be placed in the workshop inventory on a regular basis, subject to certain caps. Building multiple pumps and purifiers increases surplus production accordingly.
More details on how the game engine handles water production and usage can be found under water purifiers. The Sole Survivor can activate a water pump to drink. Drinking from a water pump will heal damage (and quench thirst in Survival mode), without inflicting radiation damage.
Water pumps must be placed on dirt or in a garden plot. Stone and pavement are generally unacceptable terrain, but if there are visible cracks sometimes a water pump can be placed. The water pump is located under Resources → Water.

In Survival mode, a water pump can also be used to fill empty bottles with purified water.
