DrainSimFlood Control

Read the water. Route the flow. Reclaim the city with build-specific mission plans, exact loadout data and community intelligence that never masquerades as fact.

A guide built like an operations centre.

DrainSim is not solved by a loose list of tips. Every mission ties together terrain, water sources, drains, vehicle capacity, tool weight, power routing and region-by-region completion. This guide connects those systems into one command view.

Community par-time table

Useful historical targets for the first eight missions. They are not treated as file-confirmed five-star limits.

The Legend's Guide to: Drain SimPredates stable build 0.3.1.12 and does not cover Downtown Station or Construction Site.

Direct hose-to-drain routing

Players report that pointing a discharge hose into the centre of a compatible drain can remove output with little backsplash. There is no universal snap prompt.

Steam guide and discussion reportsReported as finicky and drain-dependent.

Low-water pump backflow or over-output

Several players report that pumps running in very shallow water can appear to increase local water. Treat this as a troubleshooting lead, not a confirmed mechanic.

Shift briefing ready

Take control of the flood.

Start with the Garage loop, build a legal loadout and enter every operation knowing which facts are decoded, which are official and which still need proving.
