A method and drinking apparatus provide fresh water to a living entity confined into a restricted environment, includes a first element having opposite ends. A second element defines a capacity provided with first and second openings. The first opening is at an upper part of the second element. The first and second elements are secured at opposite ends. A third element has an upper first opening and a second opening. The third element is secured to opposite ends of the first element. Tubing has one end fluidly communicating with the second opening of the second element and an opposite end fluidly communicates with the second opening of the third element. The third element is higher than the second element so water poured in the third element flows by gravity within the second element. The first element is sufficiently rigid to prevent deformation by the fresh water.
