DrainSim

CodePeas developed and self-published DrainSim. It entered Steam Early Access on March 3, 2026, exclusively on PC via Steam for Windows. The game is a casual first-person drainage and flood management sim where you take control of a flooded city and clear its submerged streets one drain at a time. Furthermore, it ships with complete core gameplay systems, a water physics simulation engine, multiple playable levels, and a full range of tools, giving Early Access players a fully functional foundation from day one.

About the Game

DrainSim puts you in the role of the city’s drainage specialist. The streets are flooded, residents are waiting, and the water is not going anywhere on its own. Your job is to locate blocked and overwhelmed drains, deploy the right tools, and restore flow across every affected area of the city. Furthermore, the game leans into the satisfying sensory experience of watching water recede, channels clear, and streets return to normal under your expert attention. As a result, it occupies the same relaxing power-fantasy niche as PowerWash Simulator and Unpacking, where the pleasure comes from the act of restoring order rather than from competition or combat.

Water Physics and Tool-Based Gameplay

The water simulation in DrainSim is the technical core of the experience. Water accumulates, flows, and responds to drainage in a physics-driven way rather than through simple scripted animations. Each tool you deploy interacts with that simulation differently, giving the work a tactile quality that static environment games cannot match. Furthermore, understanding how water behaves in each situation is the skill that separates an efficient drainage run from a slow and frustrating one. Consequently, the physics layer gives the game genuine replay value beyond its initial novelty.

Tools and Progression

DrainSim gives you a wide range of tools spanning manual and mechanical options. Rakes clear surface debris that blocks drain covers. Submersible pumps handle deeper standing water that manual tools cannot reach. Furthermore, each level presents a different combination of flood conditions, drainage infrastructure, and blockage types that require matching your tool selection to the specific problem at hand. Therefore, tool management and situational awareness matter throughout the game rather than a single approach working in every situation.

Key Features

Simulation and Tools

Full Water Physics Simulation with Dynamic Flooding: The flooding in DrainSim behaves according to physical rules rather than preset animations. Water finds its own level, pools in low areas, and flows through cleared channels in real time as you work. Furthermore, clearing one section of a blocked drain system can trigger cascading improvements across adjacent areas simultaneously. As a result, the feedback loop of cause and effect makes each successful intervention feel genuinely satisfying rather than cosmetic.
Wide Range of Drainage Tools from Rakes to Submersible Pumps: The tool roster covers everything from basic manual implements to powered mechanical equipment. Rakes and manual tools are available from the start and handle surface-level blockages quickly. Submersible pumps and heavier equipment address the deeper and more serious flooding scenarios that appear in later levels. Furthermore, selecting the wrong tool for a situation wastes time and slows the job down. Consequently, learning which tool works best in each context is a genuine skill that improves your efficiency across the city.

Progression and Early Access Roadmap

Multiple Playable Levels with Varied Flood Scenarios: Each level in DrainSim presents a distinct urban environment with its own drainage infrastructure layout and flooding pattern. Some areas have simple surface blockages that clear quickly with basic tools. Others involve complex underground drain networks where the source of the flooding is not immediately visible. Furthermore, the Early Access roadmap commits to adding new levels, new tool types, and expanded environmental variety as development continues. As a result, players who join during Early Access will see the game grow substantially beyond its launch content.
Casual, Relaxing Gameplay Designed for All Skill Levels: DrainSim has no combat, no timers by default, and no failure states that punish exploration. The pace is entirely controlled by the player, making it accessible to anyone regardless of gaming experience. Furthermore, the game’s full controller support means it plays comfortably from a couch on any PC setup. Consequently, DrainSim targets the same broad audience that made PowerWash Simulator and similar titles breakout hits, prioritising enjoyment of the task over competitive or reflex-based challenge.
