## Summary

Rolling Hills Water Service reported **33.4% non-revenue water** in FY2024, higher than 79% of the 908 Texas systems that filed that year. At the utility's own reported water rates that is **$5,838 a year**, as computed in the filed audit itself. **The series is not stable enough to act on**: it moves 14.6 points a year against a Texas median of 5.8.

**The filed balance closes**, to within 0.00% of reported system input.

## Filed history

| Year | Non-revenue water % | System input (MG) | Cost of losses/yr | Balance |
|---|---|---|---|---|
| 2024 | 33.4% | 3.35 | $5,838 | closed |
| 2022 | 18.6% | 2.65 | $905 | closed |
| 2019 | 24.7% | 2.23 | $1,138 | closed |
| 2017 | 47.5% | 3.32 | $4,206 | closed |

`closed` means the filed components sum to the filed input. `failed` means they do not, by the stated residual.
`insufficient` means the check could not run because figures are missing — never to be read as a pass.

## How the cost figure is built

Apparent loss is water delivered and never billed, so it is valued at the retail rate: revenue, recoverable inside a
budget year without capital work. Real loss is valued at variable production cost, because eliminating a leak saves
treatment and pumping rather than retail price. Where the filed audit carries its own cost of losses — as TWDB's
export does — those figures are used directly and no rate of ours enters the calculation.

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
