Gwinnett County Dwr
What Gwinnett County Dwr filed with EPD about the water it produced and the water it billed for, 2011–2025 — and what the filing does and does not let anyone verify.
- Non-revenue water, FY2025
- 9.6% Computed from filed system input and billed consumption.
- system input volume 29,376 sheet 2025 Water Audits , cell H104 · million gallons per year, declared in the header through 2020 and settled for 2021-2025 by EPD's own cost arithmetic and by continuity across the change
- billed authorized consumption 26,556 sheet 2025 Water Audits , cell I104 · billed metered plus billed unmetered
- Recoverable annually
- $5.3M Apparent loss is valued at this utility's own reported retail price of water. Real loss is NOT included — EPD 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 5,253,295 sheet 2025 Water Audits , cell Z104
- Balance check
- inapplicable EPD derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

What the record shows
9.6% non-revenue water in FY2025, higher than 11% of the 228 Georgia systems that filed that year.
- The figure is improving across the record.
Compliance record
7 violations on EPA's record for this system as of 2026Q2. 7 resolved, 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.

EPD 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 $5.3M 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.
