Water purifier (Fallout 4)

A water purifier is a settlement object in Fallout 4.

Characteristics
The water purifier and industrial water purifier generate varying amounts of purified water in whichever settlement they are built in. Their production rates are much higher than that of a basic pump (10 and 40 respectively, instead of 3), usually making them the superior choice. However, this is counterbalanced by their need for electrical power, the considerably larger amounts of crafting components required to build them and the fact that only a handful of settlements can support purifiers at all (refer to the list below).

Similarly to water pumps, should the water production exceed the settlement's demand, any excess water will be placed in the workshop inventory on a regular basis. Building multiple purifiers increases the surplus production accordingly.

When setting up such an operation, some things are important to keep in mind:
 * Any settlement's defense rating should be equal to or higher than the sum of its food and water production. Shoring up the settlement's defenses is mandatory to minimize the risk of raider attacks but can cost a lot of resources, depending on the amount of purifiers installed.
 * The amount of excess water that can be stored in a settlement is limited to 200 units. Anything produced beyond that limit is lost. In order to make the most of one's production capabilities, one should stop by the settlement regularly to pick up the produce and avoid wasting water.

Requirements

 * Water purifiers must be placed on top of a water source such as a stream or pond, and require power to operate.

Possible building sites
Not all settlements offer the opportunity to build water purifiers due to a lack of suitable water sources. Below is a list of settlements that can support at least one purifier.
 * County Crossing
 * Echo Lake Lumber
 * Egret Tours Marina
 * Finch farm
 * Kingsport Lighthouse
 * Murkwater construction site
 * Sanctuary Hills
 * Spectacle Island (allows for the production of 10,000+ units of water)
 * Starlight Drive In
 * Taffington boathouse
 * The Castle (completing Taking Independence automatically activates one industrial purifier)
 * The Slog
 * Warwick homestead
