Milton Municipal Water

What Milton Municipal 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.

The components PSC publishes contradict each other, which is a defect in the export rather than in the filing.

Debt outstanding, and what covers the interest

$1.1M of long-term debt outstanding at the end of 2025, across 1 bond issue. This is principal outstanding on the water utility's own balance sheet, on the Commission's own test: it files no electric operating report.

8.74 — what Milton Municipal 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.

5 filed values that cannot be true.
  • 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.
  • The components PSC publishes for FY2024 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.
  • The components PSC publishes for FY2023 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.
  • The components PSC publishes for FY2022 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.
  • The components PSC publishes for FY2021 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.

Water balance, FY2025 · 381.5 MG system input
Billed 819.6 MG Unbilled authorized 6.2 MG Apparent loss 0 MG Real loss 37.4 MG
The components PSC publishes sum to 863.2 MG against the system input it publishes for the same filing, 381.5 MG — a difference of 481.7 MG. Every total in this export is computed from the others, so the parts cannot disagree unless a value was mis-transcribed. This is a defect in the data as published, not in what the utility filed.

Balance closure is inapplicable on every filed year above, so the column that repeated it is not shown. FY2021–FY2025: The components PSC publishes contradict each other, which is a defect in the export rather than in the filing. FY2016–FY2020: 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.

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 says how much. It cannot say which accounts, which zones, or which meters. That 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.
