Separate water-management settings from network failure
Water treatment matters only in a republic whose settings require water management. Raw surface or well water is distinct from treated drinking water. The wiki states that citizen drinking water under 97% can cause illness, while factories may have different input needs; do not apply the citizen threshold indiscriminately to every consumer.
- Check whether water management is enabled in the current save settings.
- Identify whether the source is a well, surface outflow, imported water or another source; record its displayed quality.
- Name the affected consumer type: residential drinking water, factory process water or worker drinking water.
- Read the consumer's supplied quality and delivery status before changing the treatment target.

Find the limiting quantity in the treatment step
The official wiki warns that listed water-treatment production can overstate actual output when the plant must remove substantial impurity: its maximum daily throughput depends on wastewater capacity divided by the amount of quality improvement. It gives a concrete example with a 30 m³/day wastewater limit and a 20-point improvement, yielding 150 m³/day. This is a documented example, not a promise that every plant or input source has those exact values.
- Check whether the treatment building has workers; the wiki says unstaffed treatment stops and can leave consumers without water.
- Record source quality and the configured target quality from the treatment interface.
- Inspect the plant's wastewater output/cap and any visible treatment warning.
- Use the 30 ÷ 0.20 = 150 m³/day example only to understand the relationship; enter your own same-unit values if using an arithmetic worksheet.
- If the water is already high quality but delivery fails, move to pipes, substations, pumps or truck assignment rather than raising the quality target.
| Finding | Likely gate to inspect next | Avoid concluding |
|---|---|---|
| Target quality is far above source quality | Treatment impurity removal and wastewater limit | That nominal input capacity equals usable output |
| Treatment has no workers | Staffing and worker access | That the treatment plant is malfunctioning |
| Quality meets target but homes lack water | Distribution, substation elevation/range, pump or supply route | That more treatment capacity is necessarily needed |
| Homes receive below cited 97% | Treatment target/source quality and route contamination | That every factory uses the same consumer threshold |

Verify the result at the consumer
A higher plant target is not itself proof of safe delivery or adequate quantity. The official water page notes that substation reach changes with terrain height and that pumping stations move water uphill; the final check is the consumer's own supply and quality status.
- After a single treatment or distribution change, recheck water quality and availability at the affected building.
- If plant output is now adequate but coverage remains missing, inspect pipe size/connection and elevation-aware substation reach.
- For truck delivery, verify the technical-services assignment and a valid loading source.
- Record the current build, setting, source type, displayed target and observed output before asking a community forum; treat replies as player reports, not confirmed fixes.

Before you play
- Water-management setting verified.
- Source type and source quality noted.
- Consumer type distinguished from residential drinking water.
- Treatment target and wastewater capacity checked separately.
- Plant staffing and delivery route verified.
- Final quality/availability confirmed at a consumer, not inferred from plant output.
Frequently asked questions
Why is treatment output lower than the plant's nominal capacity?
The official wiki says wastewater capacity can constrain output when treating significantly impure surface water; use the current plant readout and source/target quality to diagnose.
What drinking-water quality do citizens need?
The cited official wiki states at least 97% for citizens. Recheck current in-game information for the save's build and settings.
Can I set the water target to 99% and assume the city is safe?
No. The plant must be staffed and the network must deliver the water; verify quality at the consumer and confirm current mechanics.
