The small number of people served makes the cost striking. Pipes, connections and dependable pressure have to be provided even where there are few customers to share the expense. For this project, the regional environmental fund announced more than PLN 1.03 million in support combining a grant and a loan. Keeping the taps working requires money from outside the immediate group of households.

The European Commission’s 2026 country report identifies freshwater scarcity as a serious constraint in Poland. Distribution adds another demand on those resources: water can be abstracted, treated and pumped before the network loses it. Repairing that loss protects the work already paid for, alongside the separate tasks of retention, pollution control and managing industrial demand.

Customers were not told what the networks lost

A Supreme Audit Office report on West Pomeranian water companies shows how poorly this part of the service could be accounted for. The audit covered five operators during 2021–2023. At the end of 2023, 23 of their 38 networks had losses exceeding 20% of the water put into the system. These are findings from that regional audit, not an estimate for Poland today.

None of the five companies told customers about the scale and cost of those losses. They also did not calculate how lost water affected the price of water sold. Residents could see a tariff without seeing this part of the operating problem behind it.

The reported losses need care in interpretation. The audit found unauthorised withdrawals and weaknesses in metering as well as infrastructure problems. A water-balance loss figure cannot all be treated as water leaking underground. Identifying the cause determines whether the response should be pipe work, better measurement or stopping an unregistered withdrawal.

That is a management task with a public consequence. When a utility cannot explain what it loses, its owner and customers have less information for deciding whether spending is adequate or effective. Nor can a reader turn a loss percentage into an equivalent percentage reduction in the household bill. Finding faults, repairing pipes and servicing loans also cost money.

Wrocław made leak detection part of the job

The Wrocław municipal portal’s April 2026 account describes a different operating approach. MPWiK reports that its loss rate fell from 5.02% in 2024 to 4.04% in 2025. It located 251 hidden faults in 2025, after 157 the previous year.

The company attributes the result to work developed over more than a decade: dividing the network into monitoring zones, analysing flows and using the SmartFlow system introduced in 2016. Its account names the people involved, including diagnosticians, fitters, dispatchers, engineers and planners. A monitoring system needs people able to investigate an anomaly and act on it.

Those are operator-reported results. They show a documented approach, rather than proving that another town would achieve the same percentage by buying the same technology. Network layout, pressure, customer density and measurement methods differ. The useful lesson is that searching for hidden faults became continuing work, with results reported from one year to the next.

This is less visible than opening a new treatment plant. It is also necessary to keep the benefits of one. Singapore’s water-reuse system illustrates how investment upstream can expand supply; losses further along the delivery network can still reduce what that investment achieves.

Small networks still need someone to pay

Kaniów brings the financing question back to ground level. The announced grant-and-loan package helps fund a substantial local repair. It cannot, by itself, show how well the rebuilt network will be maintained or whether the promised loss reduction will last. That requires subsequent operating results. A loan also remains a financial commitment; the whole support package should not be described as free money.

The regional difference matters. A small customer base still needs reliable service, and leaving maintenance until revenue comfortably covers it can mean accepting deterioration. This is a concrete infrastructure problem within the wider disconnection of Poland’s smaller towns. Public financing can spread the cost of repair beyond the people living along a particular pipe.

Poland’s drinking-water amendment that took effect on 21 May 2026 lists reducing losses and improving information among its aims. Better information would help residents judge the investment as well as the tariff: what was repaired, what losses remain and how performance has changed. That is also part of the question raised by the Emscher river restoration: who receives a lasting improvement from public spending?

For the Kaniów project, the next result to look for is the loss rate after the work. The fund has published the target and the financing. Reporting subsequent performance would let residents see what that spending delivered, and whether the improvement lasts.
