California - American Water Company - Monterey District - Ralph Lane

What California - American Water Company - Monterey District - Ralph Lane filed with DWR about the water it produced and the water it billed for, 2017–2024 — and what the filing does and does not let anyone verify.

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

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

What the record shows

4.8% non-revenue water in FY2024, higher than 14% of the 545 California systems that filed that year.

4.8% 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 4.8%. 1 filing above 64% are drawn at the right edge.0%10%20%30%40%50%60%This system 4.8%California median 9.2%
The reported figure is not stable enough to act on. It has moved an average of 12 points a year, against a California median of 2.6, including 41% to 12% between FY2020 and FY2021. 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

No bill is published for this system. Our computation from this system's filed rate structure and the Board's own undocumented charge field for the same volume disagree, and the field carries no definition to settle which is right.

It did answer the Board's customer-charge questions for reporting year 2025; what is missing is what a comparable figure needs.

Compliance record

5 violations on EPA's record for this system as of 2026Q2, of which 3 are health-based. 4 resolved, 1 archived, 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.

A filed value that cannot be true.
  • FY2024 reports a leakage index of 0.00443712814629112, which would mean less real loss than the unavoidable minimum the same audit computes for this network.

Each is reproduced exactly as filed and excluded from every figure computed on this page. A number that contradicts its own audit is a finding about the filing, not a gap in ours.

Who filed this audit

California American Water Company - Monterey District filed 7 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 American Water Company - Monterey District made one set of decisions and filed it 7 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.

Where is it going?

This page says how much — roughly $331 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.
