Cws Av Leona Valley

What Cws Av Leona Valley filed with DWR about the water it produced and the water it billed for, 2016–2024 — and what the filing does and does not let anyone verify.

Non-revenue water, FY2024
18.2%

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.

Balance check
inapplicable
DWR derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

What the record shows

18.2% non-revenue water in FY2024, higher than 81% of the 545 California systems that filed that year.

18.2% non-revenue water in FY2024, against 545 California filings for the same yearA strip of 545 filings on a 0 to 64% axis. The median is 9.2%. This system is 18.2%. 1 filing above 64% are drawn at the right edge.0%10%20%30%40%50%60%This system 18.2%California median 9.2%
The reported figure is not stable enough to act on. It has moved an average of 5 points a year, against a California median of 2.6, including 18% to 5% between FY2017 and FY2018. A distribution system's real losses do not change that fast — pipe does not deteriorate or repair itself in a single year. A series that moves like this is describing how the water is being measured and recorded, not how much of it is being lost, and which year is closer to true cannot be settled from this filing.

What it charges

$40.73 a month for a household using 6 hundred cubic feet — 4,488 gallons — and $190.17 at 17,952 gallons. Computed from the fixed charge and the tiers this system filed for reporting year 2025, not read off a rate sheet.

The fixed charge is $29.38 a month before any water is used. Billing is monthly, quoted in hundred cubic feet.

Where this figure comes from

From data/archive/ca-ear-rates/2026-09-09-6eba0fd85f1f-section8-charges.jsonl, extracted 2026-09-09 from the Board's published section 8a file. That file has no cells: a value is found by the system identifier and the question abbreviation above.

The Board also publishes an undocumented charge field for this volume. Our figure reproduces it to the cent, which is what establishes that the field is a bill at this volume for systems like this one.

This is what the system reported for reporting year 2025. It is not necessarily the rate in force today, and nothing in the filing says whether it has since changed.

Compliance record

1 violation on EPA's record for this system as of 2026Q2, of which 1 is health-based. 1 resolved, and 0 still open.

Nothing on the record is open as of 2026Q2.

Counted as distinct violations, not as rows: EPA's export carries one row per enforcement action taken against a violation, so a row count would multiply this system's record several times over. A violation here is a breach of a reporting, monitoring or contaminant-level rule as reported to EPA — it is not a measurement of the water, and this site has none.

Who filed this audit

California Water Service Company Antelope Valley filed 5 separate audits for FY2024, one for each public water system it operates, and this page is one of them. California keys its water loss export on the filing organization and not on the system, so a count of California audits is not a count of independent utilities. California Water Service Company Antelope Valley made one set of decisions and filed it 5 times. Read any statewide figure with that in mind, including the ones on this site.

Every figure on this page is read from DWR's published export as this site holds it: a 184-column extract of DWR's 190-column file. Six columns naming individuals, including the contact and the third-party validator, are removed before the bytes are committed, so the click path behind each figure lands on the extract and not on DWR's original. The column letters differ from DWR's for that reason.

Billed 53.9 MG Unbilled authorized 0.15 MG Apparent loss 1.37 MG Real loss 10.5 MG

DWR derives water losses from system input minus authorized consumption, so these parts sum to the whole on every filing. What a filing can get wrong is which of these numbers were measured.

Where is it going?

This page says how much — roughly $12,200 a year. It cannot say which accounts, which zones, or which meters. That takes your billing history, your meter reads, and your production data reconciled against each other.

Our Water Loss Recovery Snapshot is three weeks, one flat fee, and the deliverable is a ranked list of specific accounts and zones with dollars and a confidence on each.
