California American Water Company - Ryan Ranch
What California American Water Company - Ryan Ranch filed with DWR about the water it produced and the water it billed for, 2017–2020 — and what the filing does and does not let anyone verify.
- Non-revenue water, FY2020
- 13.3% Computed from filed system input and billed consumption.
- system input volume 16.3 sheet Sheet1, cell AN1819 · converted to million gallons from acre-feet
- billed authorized consumption 14.1 sheet Sheet1, cell AQ1819 · billed metered plus billed unmetered, converted to million gallons from acre-feet
- Annual value of the filed loss
- $7,600 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.

What the record shows
13.3% non-revenue water in FY2020, higher than 73% of the 554 California systems that filed that year.
- The figure is roughly flat across the record.
It does not establish what moved. A meter replacement program, a main break, a change of billing system, a corrected prior-year filing and an ordinary reporting error all produce a series that looks like this, and a filed water loss audit does not say which happened. What the flag does say is that the years disagree with each other by more than most of the state's do, so a single year of this series is a weak basis for a decision without the records behind it.
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 American Water Company - Monterey District filed 9 separate audits for FY2020, 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 American Water Company - Monterey District made one set of decisions and filed it 9 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.

Balance closure is inapplicable on every filed year above, so the column that repeated it is not shown. DWR derives water losses from system input minus authorized consumption, so this decomposition holds by construction. This is neither a pass nor a disclosure gap.

Where is it going?
This page values the loss at roughly $7,600 a year. It cannot say which accounts, which zones, or which meters, and it cannot say how much of that value is collectable. Answering either 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.
