The system was in use into the 20th century, providing power to Shushtar, albeit probably not as efficiently as it did before time and erosion took their toll. But considering that it was centuries old, a bit of slippage can be forgiven. Active use of the system was eventually scrapped, as its uses were replaced with more modern irrigation techniques.
