Sanger
What Sanger 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
- 15.0% Computed from filed system input and billed consumption.
- system input volume 2,154 sheet Sheet1, cell AN447 · converted to million gallons from acre-feet
- billed authorized consumption 1,831 sheet Sheet1, cell AQ447 · billed metered plus billed unmetered, converted to million gallons from acre-feet
- Recoverable annually
- $62,400 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 62,443 sheet Sheet1, cell DH447
- Balance check
- inapplicable DWR derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

What the record shows
15.0% non-revenue water in FY2025, higher than 83% of the 141 California systems that filed that year.
- The figure is getting worse across the record.
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
9 violations on EPA's record for this system as of 2026Q2, of which 7 are health-based. 7 resolved, and 2 still open.
- LSL Inventory health-based addressed, from October 17, 2024
- LSL Reporting addressed, from October 17, 2024
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
Sanger 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.
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 $62,400 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.
See what the Snapshot delivers Email us about SangerSources and corrections. Every figure above is either filed by the utility or computed from filed figures, and each one says which. If a number here is wrong, it is either wrong in the filing or wrong in our reading of it — tell us which and we will correct the page and say what changed.
