What is ProSewers?

ProSewers is a procedural sewer generation plugin designed for Minecraft roleplay .

Instead of manually building underground tunnels block by block, admins can create surface nodes on roads, sidewalks or city points, then connect them to generate a complete underground sewer system automatically.

The plugin creates large walkable tunnels, underground chambers, dirty walls, broken slabs, drainage canals, pipes, water leaks, ladders, manhole covers and connected routes under the city.

It is perfect for:

• Modern roleplay cities
• Police chases
• Criminal escapes
• Hidden routes
• Rat / monster areas
• Secret bases
• Underground missions
• Urban exploration
• Maintenance worker roleplay
• Event zones

Designed for Roleplay

ProSewers is not just a tunnel generator. It is designed to create useful underground spaces for real gameplay.

Players can:

• Run through the sewers during police chases.
• Hide inside dirty side areas.
• Escape through alternate city routes.
• Explore abandoned underground tunnels.
• Find rats or hostile mobs in dark sewer sections.
• Use manholes as access points.
• Discover underground chambers and intersections.

Admins can build an entire sewer network under a city using simple commands.


How it Works

Create a node on the surface:

The plugin stores the surface position and calculates the sewer position below it:

By default:

Then connect two nodes:

The plugin generates an underground tunnel between both nodes. If both nodes are at different heights, the tunnel creates slopes and transition sections instead of breaking the route.

Default Visual Style

The default generation uses an aged underground city style with blocks such as:

• Deepslate Bricks
• Cracked Deepslate Bricks
• Deepslate Tiles
• Cracked Deepslate Tiles
• Mossy Stone Bricks
• Cobblestone
• Mossy Cobblestone
• Mud
• Gravel
• Tuff Bricks
• Iron Bars
• Water
• Chains
• Lanterns
• Ladders

This creates a sewer that feels dirty, old, broken and useful for urban roleplay.
