Port Hueneme

What Port Hueneme 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

Recoverable annually
$84,500
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

7.5% non-revenue water in FY2024, higher than 38% of the 545 California systems that filed that year.

7.5% 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 7.5%. 1 filing above 64% are drawn at the right edge.0%10%20%30%40%50%60%This system 7.5%California median 9.2%
The reported figure is not stable enough to act on. It has moved an average of 4.6 points a year, against a California median of 2.6, including 13% to 4% between FY2022 and FY2023. 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

$63.94 a month for a household using 6 hundred cubic feet — 4,488 gallons — and $191.18 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 $26.78 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

8 violations on EPA's record for this system as of 2026Q2. 3 resolved, 5 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.

2 filed values that cannot be true.
  • FY2020 reports a leakage index of 0.00707223183875706, which would mean less real loss than the unavoidable minimum the same audit computes for this network.
  • FY2018 reports a leakage index of 0.0892556511403984, 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

Port Hueneme City Of filed this audit for FY2024 and operates no other system in the export that year. California keys its export on the filing organization and not on the system, so the two coincide here rather than by definition.

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 $84,500 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.
