A change in volume or equipment calls for comparison with the original title.
Set out the previous and current use side by side. Record the abstraction volume, pipeline route and dimensions, pumping equipment, operating hours and agreed purpose. Section 484 ABGB ties the scope of an easement to its nature and the purpose for which it was created. A technical change alone does not settle the issue.
Check whether the contract or instrument sets specific limits for volume, route or operation.
