## Summary

Camarillo reported **5.3% non-revenue water** in FY2025, higher than 27% of the 141 California systems that filed that year. At the utility's own reported water rates that is **$310,000 a year**, as computed in the filed audit itself. Apparent loss is valued at this utility's own reported retail price of water. Real loss is NOT included — DWR publishes a variable production cost whose unit it does not declare, so no dollar figure is put on the leaked water. The real recoverable total is higher than this by an amount this filing does not let anyone state. The figure is trending worse across the record.

**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.

- FY2018 reports a leakage index of 0.0574914324249083, which would mean less real loss than the unavoidable minimum the same audit computes for this network.
- FY2017 reports a leakage index of 0.040548477549441, which would mean less real loss than the unavoidable minimum the same audit computes for this network.

## 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.

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

## What it charges

Monthly bill at 6 HCF (4488 gallons): **$52.28**
Monthly bill at 24 HCF (17952 gallons): **$151.19**
Fixed charge: $32.48 · billing monthly · quoted in Hundred Cubic Feet

Computed from the fixed charge and tiers this system filed in section 8a of the 2025 electronic Annual
Report, not read off a rate sheet. Our figure reproduces the Board's own undocumented charge field for this volume to the cent.

This is the reporting year 2025 filing. It is not necessarily the rate in force today.

Where it comes from: the Board's section 8a file for reporting year 2025, https://www.waterboards.ca.gov/drinking_water/certlic/drinkingwater/documents/ear/2025/eAR2025_Section8.txt, held here as
archive extract sha256 7c9670802170. That file has no cells — a value is located by the system identifier
and the question abbreviation — so this figure was computed from WRSFCostPerUOM1, WRUOM, WRSFUsageCost1, WRSFUsageCost2, WRSFUsageCost3, WRSFMetricUsage1, WRSFMetricUsage2, WRSFMetricUsage3 for system CA5610019.

The twin cites the extract by hash rather than by path because the path is named for the day it was written,
and a date in a corpus twin is a build clock that churns every page claim daily. The page itself carries the
path.

## Compliance record

EPA's Safe Drinking Water Information System carries no violation for this system in the 2026Q2
download. That is a statement about the record: SDWIS completeness varies by primacy agency and by quarter, so
an empty record is not the same as a system that has never been in violation.
