## 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) |

## 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.
