Evansville Water & Sewer
What Evansville Water & Sewer filed with IFA about the water it produced and the water it billed for, 2019–2023 — and what the filing does and does not let anyone verify.
- Non-revenue water, FY2023
- 7.9% Computed from filed system input and billed consumption.
- system input volume 6,714 sheet Sheet1, cell H125 · million gallons per year, declared in the column header in all three vintages
- billed authorized consumption 6,183 sheet Sheet1, cell I125 · billed metered plus billed unmetered
- Recoverable annually
- $3.4M Apparent loss is valued at this utility's own reported retail price of water. Real loss is NOT included — IFA publishes a variable production cost whose unit it does not declare, so no dollar figure is put on the leaked water. The real recoverable total is higher than this by an amount this filing does not let anyone state.
- cost of apparent losses, as filed 3,424,751 sheet Sheet1, cell AA125
- Balance check
- inapplicable IFA derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

What the record shows
7.9% non-revenue water in FY2023, higher than 11% of the 430 Indiana systems that filed that year.
- 1 of 3 years carry no figure — which by IFA's own note means it had insufficient data to calculate one.
Compliance record
22 violations on EPA's record for this system as of 2026Q2. 5 resolved, 17 archived, and 0 still open.
Nothing on the record is open as of 2026Q2.
Counted as distinct violations, not as rows: EPA's export carries one row per enforcement action taken against a violation, so a row count would multiply this system's record several times over. A violation here is a breach of a reporting, monitoring or contaminant-level rule as reported to EPA — it is not a measurement of the water, and this site has none.

- The FY2021 volumes are not published here because the filing contradicts itself — 107,838 gal/person/day implied by this filing's own system input and population.
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.
IFA 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 is it going?
This page says how much — roughly $3.4M a year. 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.

Every figure above is either filed by the utility or computed from filed figures, and each one says which. If a number here is wrong, it is either wrong in the filing or wrong in our reading of it — tell us which and we will correct the page and say what changed.
