Sacramento County Water Agency - Northgate 880
What Sacramento County Water Agency - Northgate 880 filed with DWR about the water it produced and the water it billed for, 2019–2024 — and what the filing does and does not let anyone verify.
- Non-revenue water, FY2024
- 22.6% Computed from filed system input and billed consumption.
- system input volume 355.8 sheet Sheet1, cell AN2683 · converted to million gallons from acre-feet
- billed authorized consumption 275.5 sheet Sheet1, cell AQ2683 · billed metered plus billed unmetered, converted to million gallons from acre-feet
- Recoverable annually
- $11,900 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 11,876 sheet Sheet1, cell DH2683
- Balance check
- inapplicable DWR derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

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
Sacramento County Water Agency filed 8 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. Sacramento County Water Agency made one set of decisions and filed it 8 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.
