More Drainage Channels for Anno 117: Pax Romana is a mod designed to optimize gameplay by increasing the capacity and efficiency of drainage systems. This modification allows each sluice gate to support more drainage channels, boosting the base capacity from 75 to 100 and the upgrade capacity from 80 to 150. Additionally, it expands the drainage width from 8 to 12 tiles per side, enabling players to manage larger swamp areas with fewer sluice gates, thereby maintaining balance in the game's mechanics.

The mod also offers optional adjustments through the assets.xml file, allowing users to customize base pipe capacity, upgrade bonuses, drainage width, and maintenance costs. Installation is straightforward, requiring users to download the mod from Mod.io and extract it into the appropriate Anno 117 mod folder. After installation, players can restart the game to access the enhanced features, providing a richer gameplay experience.
