## Summary

La Salle WCID 1-a reported **11.9% non-revenue water** in FY2022, higher than 32% of the 740 Texas systems that filed that year. At the utility's own reported water rates that is **$32,742 a year**, as computed in the filed audit itself. **The series is not stable enough to act on**: it moves 9.5 points a year against a Texas median of 5.8.

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

`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
