South Milwaukee Water
What South Milwaukee 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
- 22.9% Computed from filed system input and billed consumption.
- system input volume 508 sheet Sheet1, cell H473 · 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 391.6 sheet Sheet1, cell I473 · 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.

Read from data/archive/wi-psc-water-audit/2026-09-08-5ef7d6e2fdbd.csv (SHA-256 5ef7d6e2fdbdac2b), our archived copy of the file as it stood on 2026-09-08. That path is committed to the repository and is not served here. The agency publishes its own current copy at https://apps.psc.wi.gov/ARS/WEGSqueries/default.aspx, which may since have been revised.
What the record shows
22.9% non-revenue water in FY2025, higher than 70% of the 562 Wisconsin systems that filed that year.
- The figure is roughly flat across the record.
- The figure moved from 24% to 5% between FY2021 and FY2022.
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.
| Year | Debt outstanding | Issues | Net revenue | Interest | Coverage |
|---|---|---|---|---|---|
| 2025 | $0 | 0 | $2.3M | $218,130 | 10.38 |

10.38 — what South Milwaukee Water's net revenue was against its interest in 2025.
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.

- The components PSC publishes for FY2025 do not sum to the system input it publishes for the same filing — a defect in the published export, not in what the utility filed.
Each is reproduced exactly as filed and excluded from every figure computed on this page. A number that contradicts its own audit is a finding about the filing, not a gap in ours.

Balance closure is inapplicable on every filed year above, so the column that repeated it is not shown. FY2016–FY2024: PSC derives water losses from system input minus authorized consumption, so this decomposition holds by construction. FY2025: The components PSC publishes contradict each other, which is a defect in the export rather than in the filing. This is neither a pass nor a disclosure gap.
Other Wisconsin systems
PSC publishes no county or connection count for these systems, so they cannot be ranked against this one. These are other filers, not comparables.

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.
