I don't see why anyone in Sartar would use irrigation, other than (maybe) fetching and carrying buckets of water for their vegetable gardens. When someone uses the word "irrigation", I get the picture of large scale screws and wheels driven by oxen, and trenches, and rice-paddies and the like.
This does not fit my mental image of Sartarite agriculture.
However, to each his own.
