## Summary

Amador Water Agency - Pg&e reported **0.7% non-revenue water** in FY2024, higher than 0% of the 545 California systems that filed that year. **The series is not stable enough to act on**: it moves 12.4 points a year against a California median of 2.6.

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

**2 filed values that cannot be true.** Each is reproduced exactly as filed and excluded from every figure computed here. A number that contradicts its own audit is a finding about the filing, not a gap in ours.

- FY2024 reports a leakage index of 8.91532411360258e-16, which would mean less real loss than the unavoidable minimum the same audit computes for this network.
- FY2023 reports a leakage index of 0.00883832872971302, which would mean less real loss than the unavoidable minimum the same audit computes for this network.

The Balance column carries more than one verdict on this system. `inapplicable` is a statement about the
source rather than the utility: DWR derives water losses from system input minus
authorized consumption, so the identity holds on every filing where it publishes all the components.
`insufficient` means the filing does not publish enough components to decompose at all. Neither is a pass or a
failure.

## 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
DWR's export does — those figures are used directly and no rate of ours enters the
calculation.

The FY2024 loss figure: (system input − billed authorized) ÷ system input × 100, from system input volume at `Sheet1!AN84`; billed authorized consumption at `Sheet1!AQ84` — in `data/archive/ca-dwr-water-loss/2026-09-05-f0dfea5a6026.csv` (sha256 f0dfea5a6026881d, retrieved 2026-09-05, https://data.cnra.ca.gov/dataset/d6cdd89e-49b0-4b1f-86ee-8b7237e5f169/resource/058ac6ca-a8b4-4f28-b6c8-11e48309f3b4/download/ca-retailer-waterlossdata.csv), read by `src/scrape/ca.ts` at eaf9ca89f144.

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: **2** (1 health-based).
Resolved: 2. 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.
