Cws Av Lancaster
What Cws Av Lancaster 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
- 11.9% Computed from filed system input and billed consumption.
- system input volume 126.1 sheet Sheet1, cell AN889 · converted to million gallons from acre-feet
- billed authorized consumption 111.1 sheet Sheet1, cell AQ889 · billed metered plus billed unmetered, converted to million gallons from acre-feet
- Recoverable annually
- $25,100 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.
- cost of apparent losses, as filed 25,144 sheet Sheet1, cell DH889
- Balance check
- inapplicable DWR derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

What the record shows
11.9% non-revenue water in FY2024, higher than 62% of the 545 California systems that filed that year.
- The figure is getting worse across the record.
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.
- Tier 1, up to 6 hundred cubic feet — $1.89 per hundred cubic feet
- Tier 2, 6 to 17 hundred cubic feet — $7.57 per hundred cubic feet
- Tier 3, 17 to 25 hundred cubic feet — $9.46 per hundred cubic feet
- Tier 4, above 25 hundred cubic feet — $14.19 per hundred cubic feet
Where this figure comes from

- Volumetric tiers WRSFUsageCost1, WRSFUsageCost2, WRSFUsageCost3, WRSFUsageCost4, system CA1910010
- Tier tops WRSFMetricUsage1, WRSFMetricUsage2, WRSFMetricUsage3, WRSFMetricUsage4, system CA1910010
- Unit of measure WRUOM, system CA1910010
- Billing frequency WRFrequency, system CA1910010

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
3 violations on EPA's record for this system as of 2026Q2, of which 1 is health-based. 3 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.
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.

This page says how much — roughly $25,100 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.
