Sewer Overflow Facility Battlemap (30x40)

Description

A sewer overflow control site built from heavy stonework, aging wooden walkways, and a scattering of loose planks laid across the channels by whoever last needed to cross in a hurry. The system branches through multiple chambers — a swirling intake vortex, a pressure‑heated runoff room, and a dim‑lit basin where the flow gathers before disappearing deeper underground. Every space carries that mix of damp echo, slow movement, and the sense that the whole place is one surge away from becoming dangerous.

The layout supports infiltration scenes, tight tactical movement, environmental hazards, and encounters where footing, visibility, and sound all matter. The different chambers give you natural pacing shifts — from narrow tunnels to open flow rooms to unstable crossings.

If you’d like the high‑resolution files, gridless versions, and the full set of variants — **Steamy**, **Sludged**, and **Arcane Contamination** (as seen in the second image) — they’re available on my Patreon in both 8k and VTT‑Ready formats:
