Manhattan Beach

What Manhattan Beach filed with DWR about the water it produced and the water it billed for, 2017–2025 — and what the filing does and does not let anyone verify.

Non-revenue water, FY2025
4.5%
Computed from filed system input and billed consumption.

Recoverable annually
$210,000
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

4.5% non-revenue water in FY2025, higher than 18% of the 141 California systems that filed that year.

What it charges

No bill is published for this system. This system does not bill monthly, and a bill is per billing period — a bi-monthly fixed charge is not half a monthly one, and nothing filed says how its tiers apply to a month.

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

Compliance record

2 violations on EPA's record for this system as of 2026Q2, of which 1 is health-based. 1 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.
  • FY2019 reports a leakage index of 0.0668901763355656, 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

Manhattan Beach City Of filed this audit for FY2025 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.

Water balance, FY2025 · 1,462 MG system input
Billed 1,396 MG Unbilled authorized 4.71 MG Apparent loss 21.1 MG Real loss 40 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 $210,000 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.
