Downsville Sanitary District No 1
What Downsville Sanitary District No 1 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
- 19.3% Computed from filed system input and billed consumption.
- system input volume 4.89 sheet Sheet1, cell H141 · 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 3.95 sheet Sheet1, cell I141 · 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
19.3% non-revenue water in FY2025, higher than 58% 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
$430,043 of long-term debt outstanding at the end of 2025, across 2 bond issues. This is principal outstanding on a combined water and sewer utility's balance sheet, which the Commission files as one.

| 2025 | $430,043 | 2 |

This utility's balance sheet and income statement are water and sewer, 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. Nothing here is a credit opinion, an implied rating, or a judgement that any figure is sufficient.

- 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.
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 4.89 MG sheet Sheet1, cell H141 · 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 3.95 MG sheet Sheet1, cell I141 · thousands of gallons, declared in the column header, divided by 1,000
- Unbilled authorized 0.46 MG sheet Sheet1, cell O141 · thousands of gallons, declared in the column header, divided by 1,000
- Apparent loss 0 MG sheet Sheet1, cell R141 · thousands of gallons, declared in the column header, divided by 1,000
- Real loss 0.49 MG sheet Sheet1, cell U141 · 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. FY2016, FY2017, FY2018, FY2020, FY2021, FY2022, FY2023, FY2024, FY2025: PSC derives water losses from system input minus authorized consumption, so this decomposition holds by construction. FY2019: 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.

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.
