<P> The lagoon is a man - made lagoon which is fed by the water output of the nearby geothermal power plant Svartsengi and is renewed every two days . Superheated water is vented from the ground near a lava flow and used to run turbines that generate electricity . After going through the turbines , the steam and hot water passes through a heat exchanger to provide heat for a municipal water heating system . Then the water is fed into the lagoon for recreational and medicinal users to bathe in . </P>
