The majority of fire hydrants in Finland are below the ground surface. This is because of the deep frost during winter. Below are some pictures of these underground hydrants.

A number of tools are required to work with the fire hydrants

After hydrant usage, it should be dried to prevent freezing. This pump performs the task

In addition to the underground hydrants, there are high capacity above ground hydrants, called "water stations"
