There are hundreds of thousands of miles of similar (but less precisely built) tunnels throughout Iran. So far there’ve been no sightings of Moslems destroying those tunnels simply because they pre-date Mohammad. In fact, they jealously guard them since that’s how they get water.
I believe that you are writing about Qanats Which are also an amazing feat of engineering in the Indo-Aryan desert areas. According to the Wikipedia article, the oldest of these in Iran may date from around the time of Cyrus the Great (700 BCE).
However, in defense of this article, I don't think these qanats were built by invading forces with century+ mindsets. This aqueduct project is amazing.
