A servitude is extinguished:
1. By the vesting of the right to the servitude and the right to the servient tenement in the same person.
2. By the destruction of the servient tenement.
3. By the performance of any act upon either tenement, by the owner of the servitude, or with his assent which is incompatible with its nature or exercise; or, 4. When the servitude was acquired by enjoyment, by disuse thereof by the owner of the servitude for the period prescribed for acquiring title by enjoyment.
