Union Center Water
What Union Center Water filed with PSC about the water it produced and the water it billed for, 2016–2025 — and what the filing does and does not let anyone verify.
- Non-revenue water, FY2025
- 47.6% Computed from filed system input and billed consumption.
- system input volume 6.8 sheet Sheet1, cell H508 · thousands of gallons, declared in the column header, divided by 1,000 · net of water sold to wholesale customers, which is the volume entering this utility's own distribution system
- billed authorized consumption 3.56 sheet Sheet1, cell I508 · thousands of gallons, declared in the column header, divided by 1,000
- Annual value of the filed loss
- — Not estimable from what PSC publishes. A loss percentage cannot be priced without the volume it is a share of.

What the record shows
47.6% non-revenue water in FY2025, higher than 96% of the 562 Wisconsin systems that filed that year.
- The figure is improving across the record.
It does not establish what moved. A meter replacement program, a main break, a change of billing system, a corrected prior-year filing and an ordinary reporting error all produce a series that looks like this, and a filed water loss audit does not say which happened. What the flag does say is that the years disagree with each other by more than most of the state's do, so a single year of this series is a weak basis for a decision without the records behind it.
Debt outstanding, and what covers the interest
No bonds outstanding at the end of 2025. This is principal outstanding on the water utility's own balance sheet, on the Commission's own test: it files no electric operating report.
No bond balance is not the same as no debt. 2,310 of the 5,921 utility-years in this extract file no bonds, and many of those utilities pay interest anyway on an advance from their own municipality, which the Commission files under account 430 rather than as a bond.

31.74 — what Union Center Water's net revenue was against its interest in 2025. A figure this large means the utility pays very little interest, not that it is unusually strong — the two figures it is computed from are in the table above.
Net revenue over interest: the Commission's account 400 (operating revenue), less 401–402 (operation and maintenance), less 408 (taxes), divided by 427 plus 430 plus 431 (interest on long-term debt, on municipal advances, and other). Depreciation is filed under 403 and is not deducted, because what pays interest is cash.
This is not a debt service coverage ratio and must not be read as one. Debt service is principal repaid plus interest, and the principal repaid in a year is not filed anywhere in this source. A covenant ratio is defined in the bond documents, which set out their own revenues, their own operating expenses and their own exclusions. Two utilities with identical filed figures can have different covenant ratios.
Figures are as filed with the Commission under Wis. Admin. Code ch. PSC 185 and are not audited as presented. Nothing here is a credit opinion, an implied rating, or a judgement that any figure is sufficient.

PSC derives water losses from system input minus authorized consumption, so these parts sum to the whole on every filing. What a filing can get wrong is which of these numbers were measured.
Where these volumes come from
- System input 6.8 MG sheet Sheet1, cell H508 · thousands of gallons, declared in the column header, divided by 1,000 · net of water sold to wholesale customers, which is the volume entering this utility's own distribution system
- Billed authorized 3.56 MG sheet Sheet1, cell I508 · thousands of gallons, declared in the column header, divided by 1,000
- Unbilled authorized 0.07 MG sheet Sheet1, cell O508 · thousands of gallons, declared in the column header, divided by 1,000
- Apparent loss 0 MG sheet Sheet1, cell R508 · thousands of gallons, declared in the column header, divided by 1,000
- Real loss 3.17 MG sheet Sheet1, cell U508 · thousands of gallons, declared in the column header, divided by 1,000

Balance closure is inapplicable on every filed year above, so the column that repeated it is not shown. PSC derives water losses from system input minus authorized consumption, so this decomposition holds by construction. This is neither a pass nor a disclosure gap.

Where is it going?
This page values the loss. It cannot say which accounts, which zones, or which meters, and it cannot say how much of that value is collectable. Answering either takes your billing history, your meter reads, and your production data reconciled against each other.
Our Water Loss Recovery Snapshot is three weeks, one flat fee, and the deliverable is a ranked list of specific accounts and zones with dollars and a confidence on each.

If a number here looks wrong, tell us: the error may be in the filing, in our reading of it, or in something the export does not show. Send a correction. We will check it against the source, correct the page where it is wrong, and say what changed.
