Lompoc
What Lompoc filed with DWR about the water it produced and the water it billed for, 2020–2025 — and what the filing does and does not let anyone verify.
- Non-revenue water, FY2025
- 71.7% Computed from filed system input and billed consumption.
- system input volume 2.79 sheet Sheet1, cell AN3931 · converted to million gallons from acre-feet
- billed authorized consumption 0.79 sheet Sheet1, cell AQ3931 · billed metered plus billed unmetered, converted to million gallons from acre-feet
- Recoverable annually
- $244 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 244.3 sheet Sheet1, cell DH3931
- Balance check
- inapplicable DWR derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

What the record shows
71.7% non-revenue water in FY2025, higher than 100% of the 141 California systems that filed that year.
- The figure is getting worse across the record.
Compliance record
EPA's Safe Drinking Water Information System carries no violation for this system in the 2026Q2 download.
That is a statement about the record. SDWIS is a state-to-EPA reporting pipeline and its completeness varies by primacy agency and by quarter, so an empty record is not the same as a system that has never been in violation.
Who filed this audit
Lompoc City Of filed 2 separate audits for FY2025, 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. Lompoc City Of made one set of decisions and filed it 2 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 $244 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.

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.
