About DrainSim
DrainSim is a single‑player simulation where players restore a city’s drainage system. Each mission provides advance intel, requiring careful selection of tools while accounting for time of day, terrain and generator distance. The game features a day‑night cycle, realistic water physics and a variety of equipment from rakes to pumps.
Progress is tracked through recognition and unlockable tools, catering to casual players and seasoned pros alike. Full controller support, custom volume controls and Steam integration round out the experience on Windows.
01 / THE GUIDE
Day‑Night Cycle
The game includes a day‑night cycle that influences mission planning. Players must consider the time of day when selecting equipment, such as floodlights for evening work. This adds a strategic layer to each operation.
Realistic water physics interact with the lighting conditions, affecting visibility and tool effectiveness. Adjusting to darkness can change how quickly water is cleared.
- Schedule floodlight use for missions set after sunset.
- Test water flow early in the day to gauge later difficulty.

Tool Planning
Before each mission, players receive crucial intel and must decide which tools to bring. Factors include terrain type, distance from the generator and the need for extra equipment like pumps or shovels.
The game encourages bringing specific items such as floodlights for night work, extra pumps for multiple areas, and shovels for diggable ground.
- Map out generator distance to avoid power loss.
- Carry a shovel if the intel mentions diggable ground.

Mission Structure
Missions are presented as unique levels with varying drainage challenges. Players must manage tools and time to clear water efficiently. Success is measured by completing the drainage objectives.
Each level may require simultaneous drainage of multiple areas, prompting the use of extra pumps and generators.
- Prioritize areas with the highest water volume first.
- Deploy extra pumps when handling several zones at once.
