- Noble Fates water pump: Pumps water into your power network, feeding water wheels that generate crank power.
- Build near a river: Rivers never run dry; closed lakes eventually drain and can ruin your setup.
- Self-sustaining loop: Two pumps plus a water wheel and a hand crank can generate more power than it consumes.
- Watch shaft costs: Each crankshaft drains 0.1 crank — keep networks small and local.
- Unlock tiers: Water pump parts need Building 3–6 and Crafting 10–11 (steel couplers at the forge).
Noble Fates Water Pump Basics
The Noble Fates water pump is the centerpiece of the Riverlands update's power system. It moves water through pipes into a water wheel, which converts the falling water into crank units — the energy currency that drives new manufacturing workbenches like the loom, lumber mill, and stone splitter. A well-built pump loop runs continuously without any labor from your nobles, freeing them for farming, fighting, and construction.
Video Highlights:
- Two water pumps can feed one water wheel and generate a power surplus
- A hand crank is only needed once to kick-start the system
- Rivers are infinite water sources; closed lakes are not
- The flywheel stores up to 500 crank units like a battery bank
- Water wheels only spin when water drops onto the middle tile
The water building menu contains several distinct pieces, each with its own role. Understanding how they fit together is the difference between a perpetual power plant and a dry, dead network.
| Structure | Function | Key Detail |
|---|---|---|
| Water Pump | Moves water into the network | Core of any power loop |
| Pipe | Transports water | Water travels roughly 20+ tiles, slowly |
| Water Valve | Controls flow on/off and volume | Place between pump and wheel |
| Water Gate | Opens/closes water passages | Only needs Building 3, no power |
| Water Wheel | Converts falling water to crank | Water must hit the middle tile |
| Hand Crank | Manual power starter | Use once to boot the system |
| Flywheel | Energy storage | Holds up to 500 crank units |
Build your pump network on a river that flows in from off-map — it will never run dry. A closed lake inside your map can be pumped empty, leaving your entire power grid dead. Always scout for a true river before committing to a site.
How to Build a Self-Sustaining Pump Loop
The most reliable starter design is the closed pump-to-wheel loop. Once primed, it powers itself and produces a surplus for your machines.
Find a River
Locate a river entering and exiting your map. Rivers sourced from off-map never deplete, unlike inland lakes and puddles.
Place Two Water Pumps
Position two pumps in the river. Two pumps feeding one water wheel typically generate around 18–20 crank while consuming only about 10, creating a steady surplus.
Connect Pipes to the Water Wheel
Run pipes from the pumps so water drops onto the center tile of the water wheel. Off-center drops do nothing — the wheel only spins when water hits the middle.
Kick-Start with a Hand Crank
Attach a hand crank to the shaft network and have a noble turn it once. The pumps start moving water, the wheel spins, and the system powers itself from then on.
Add Machines and a Flywheel
Connect manufacturing workbenches through crankshafts and add a flywheel to bank up to 500 crank units for demand spikes.
There is no lever or gearbox for shafts yet. The easiest way to toggle a machine is to disconnect and reconnect its shaft link — unplugging a shaft instantly removes that machine's power demand from the network.
Power Budget: Shafts, Wheels, and Flywheels
Every crankshaft in your network consumes 0.1 crank each. That sounds trivial, but a long shaft line of 60+ segments eats more than 6 crank per interval — a serious bite out of a two-pump budget. Hover over the network readout to see live generation, consumption, and crankshaft counts.
| Component | Output / Capacity | Cost / Draw | Notes |
|---|---|---|---|
| 2 Water Pumps + Wheel | ~18–20 crank generated | ~10 crank consumed | Net positive, runs forever on a river |
| Water Wheel (5 pumps) | ~20 crank | Higher pump draw | Diminishing returns; more pumps is not always better |
| Crankshaft | — | 0.1 crank each | Limits network length severely |
| Flywheel | 500 crank storage | None when idle | Acts as your battery bank |
| Hand Crank | Manual input | Noble labor | Only needed to restart |
Because each crankshaft requires 2 lumber and 2 steel couplers, long-distance power transmission is expensive. Steel couplers need Crafting 11 at a forge (Building 6), making shaft networks a mid-game investment.
Compact Power Hut
- Three machines beside a river
- Minimal shaft length
- Cheapest to build and maintain
Multi-Hub Layout
- Several small loops across your base
- Each hub powers nearby machines
- Avoids long shaft drains
Aqueduct Pool Network
- Fill pools step by step, close gates between
- Extends water reach beyond pipe limits
- Pools evaporate and need refilling
Water from a river can travel a long way, but slowly. Water drawn from a lake or puddle tends to cap around 20 tiles. Don't plan Roman-style aqueducts spanning your whole base — small, distributed power hubs are far more practical.
Crafting Requirements and Unlock Tiers
Every piece of the water and power system has its own build and craft thresholds. Plan your noble skills around these gates so your first loop isn't stalled by missing lumber or couplers.
| Item | Requirement | Tier Notes |
|---|---|---|
| Water Gate (wooden) | Building 3 | No power needed to operate |
| Hand-crafting lumber | Crafting 8 | Bottleneck for early crossbows |
| Lumber via Lumber Mill | Crafting 10 | Preferred method at scale |
| Forge (for couplers) | Building 6 | Required for shaft production |
| Steel Couplers | Crafting 11 | 2 per crankshaft |
| Stone Splitter blocks | Crafting 14 | Endgame castle material |
Items like the crossbow require Crafting 6 but consume 12 lumber — while lumber itself needs Crafting 8 to hand-craft. Early merchants rarely stock enough lumber. Prioritize training your first crafter to level 8 before committing to lumber-hungry production.
Water Pump Setup Checklist
Riverlands Power Goals:
- Scout and settle next to a true off-map river
- Build two water pumps and one water wheel
- Drop water onto the wheel's center tile
- Kick-start the loop with a hand crank
- Add a flywheel for 500 crank of storage
- Keep shaft lines short to minimize 0.1 crank drains
A properly balanced pump loop generates a continuous power surplus without any noble labor hours. Your nobles can focus entirely on building, farming, and defense while the water does the work.
FAQ
Q: How does the Noble Fates water pump work?
The water pump moves water from a river or lake through pipes. When that water drops onto the center tile of a water wheel, the wheel spins and generates crank power, which travels through crankshafts to run manufacturing machines like the loom, lumber mill, and stone splitter.
Q: Can a water pump system run forever?
If built on a river that flows in from off-map, yes — the river never depletes, and a two-pump loop generates more power than it consumes. If you pump from a closed lake, the water will eventually run out and the network will stop.
Q: Why isn't my water wheel spinning?
Water must fall directly onto the middle tile of the water wheel, either from a pipe or an aqueduct drop. Water landing on the side tiles does nothing. Also avoid running a shaft straight through the wheel — connect shafts to the sides instead.
Q: How far can water travel through pipes?
Water drawn from a lake or puddle travels roughly 20 tiles. Water from a true river can go further, but moves very slowly. For distant farms, build small pool networks with gates and refill them over time.
