## Summary

Philadelphia Waterworks - Ninestar Connect reported **55.8% non-revenue water** in FY2021, higher than 96% of the 383 Indiana systems that filed that year.

**The water balance is not a check here.** IFA derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

## Filed history

| Year | Non-revenue water % | System input (MG) |
|---|---|---|
| 2021 | 55.8% | 0.6 |

Balance closure is `inapplicable` on every filed year above, so the column that repeated it is
not shown. IFA derives water losses from system input minus authorized consumption, so this decomposition holds by construction. This is neither a pass nor a disclosure gap.

## What this source cannot say

No filed year on this page carries a retail rate or a production cost, so no figure here is valued. A loss volume
is not a loss in dollars, and this site will not supply a price that was not filed.

The FY2021 loss figure: (system input − billed authorized) ÷ system input × 100, from system input volume at `Sheet1!H298`; billed authorized consumption at `Sheet1!I298` — in `data/archive/in-ifa-water-loss/2026-09-08-b0699cbe4f4e.xlsx` (sha256 b0699cbe4f4ea882, retrieved 2026-09-08, https://www.in.gov/ifa/files/2022-Appendix-B-for-Water-Loss-Report-revised-Aug2023.xlsx), read by `src/scrape/in.ts` at c395acf0ba31.

Volumes are normalized to million gallons on ingest; the export reports them in the unit each filing states.

Figures are as filed unless stated otherwise. If a number here is wrong it is wrong in the filing or wrong in
our reading of it, and both are worth knowing: ammar@municorn.us

## Compliance record

Violations on EPA's record as of 2026Q2: **1** (0 health-based).
Resolved: 1. Archived: 0. **Still open: 0.**

Nothing on the record is open as of 2026Q2.

Counted as distinct violations rather than as rows: EPA's export carries one row per enforcement action taken
against a violation. A violation is a breach of a reporting, monitoring or contaminant-level rule as reported
to EPA; it is not a measurement of the water.
