Water tower

Water towers are large elevated water storage containers constructed for the purpose of holding a water supply at a height sufficient to pressurize a water distribution system. Across the wasteland, they can usually be found in the vicinity of pre-War settlements.

Although they have suffered 200 years of disrepair, many water towers still contain water and can be used to replenish Hit Points at the cost of a moderate amount of radiation.

Behind the scenes
The water towers seen in Fallout 3 and Fallout: New Vegas are marked with the name "McLean." Apart from being a town in the general game area of the former, two nearly identical water towers exist in the real world, both of which are found in towns along Historic Route 66. One of which is in McLean, Texas and the other in McLean, Illinois.
