New Glarus Light And

What New Glarus Light And 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
Computed from filed system input and billed consumption.

Where this figure comes from

(system input − billed authorized) ÷ system input × 100

  • system input volume 94 sheet Sheet1, cell H357 · 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 369.6 sheet Sheet1, cell I357 · thousands of gallons, declared in the column header, divided by 1,000

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.

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

7.2% non-revenue water in FY2018, higher than 14% of the 570 Wisconsin systems that filed that year.

7.2% non-revenue water in FY2018, against 570 Wisconsin filings for the same yearA strip of 570 filings on a 0 to 64% axis. The median is 16.9%. This system is 7.2%. 8 filings above 64% are drawn at the right edge.0%10%20%30%40%50%60%This system 7.2%Wisconsin median 16.9%
This series is flagged for review. The filed loss percentage has moved an average of 11.7 points a year, against a Wisconsin median of 5.1, including 19% to 7% between FY2017 and FY2018. The flag is that comparison and nothing more: mean absolute change per year, above the seventy-fifth percentile for this state.

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

$6.2M of long-term debt outstanding at the end of 2025, across 4 bond issues. This is principal outstanding on a combined water and electric utility's balance sheet, which the Commission files as one.

This utility's balance sheet and income statement are water and electric, filed as one. A coverage ratio computed from them would put one service's revenue over another service's interest.

Figures are as filed with the Commission under Wis. Admin. Code ch. PSC 185 and are not audited as presented.

4 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 FY2020 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 FY2019 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 · 94 MG system input
Billed 369.6 MG Unbilled authorized 0.63 MG Apparent loss 0 MG Real loss 3.31 MG
The components PSC publishes sum to 373.6 MG against the system input it publishes for the same filing, 94 MG — a difference of 279.6 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.

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.

Sources and corrections. Every figure above is either filed by the utility or computed from filed figures, and each one says which. 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.
