Sudbury Water District
What Sudbury Water District filed with MassDEP about the water it produced and the water it billed for, 2019–2025 — and what the filing does and does not let anyone verify.
- Unaccounted-for water, FY2024
- 6.0% As reported by the utility; the underlying volumes are not published.
- Recoverable annually
- — Not estimable from what MassDEP publishes. A loss percentage cannot be priced without the volume it is a share of.
- Balance check
- inapplicable This state does not require a component water balance.
What the record shows
6.0% unaccounted-for water in FY2024, higher than 14% of the 278 Massachusetts systems that filed that year.
- Above the 10% standard in 3 of 6 filed years.
- The figure is roughly flat across the record.
- 1 of 7 years carry no figure — which by MassDEP's own note means it had insufficient data to calculate one.
| Year | Unaccounted-for water | Residential gal/capita/day |
|---|---|---|
| 2025 | 57 | |
| 2024 | 6.0% | 55.2 |
| 2023 | 14.0% | 52.3 |
| 2022 | 14.0% | 62 |
| 2021 | 16.0% | 58 |
| 2020 | 9.0% | 65.1 |
| 2019 | 8.0% |
Standards are 10% unaccounted-for water and 65 gallons per capita per day. A blank is a year MassDEP could not calculate a value — by its own note, a system not fully metered, a master meter malfunction, seasonal population, or no report filed.

Where is it going?
This page says how much. 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.
