Amarillo Municipal

What Amarillo Municipal filed with TWDB about the water it produced and the water it billed for, 2017–2024 — and what the filing does and does not let anyone verify.

What the filing says

Amarillo Municipal serves 79,399 retail connections and about 199,371 people. Because it reports more than 3,300 connections, it is on an annual water loss audit cycle with TWDB.

What the record shows

12.4% non-revenue water in FY2024, higher than 31% of the 908 Texas systems that filed that year.

12.4% non-revenue water in FY2024, against 908 Texas filings for the same yearA strip of 908 filings on a 0 to 64% axis. The median is 17.9%. This system is 12.4%. 13 filings above 64% are drawn at the right edge.0%10%20%30%40%50%60%This system 12.4%Texas median 17.9%
This series is flagged for review. The filed loss percentage has moved an average of 7.1 points a year, against a Texas median of 4.2, including 7% to 23% between FY2021 and FY2022. The flag is that comparison and nothing more: mean absolute change per year, above the seventy-fifth percentile for this state.

It does not establish what moved. A meter replacement program, a main break, a change of billing system, a corrected prior-year filing and an ordinary reporting error all produce a series that looks like this, and a filed water loss audit does not say which happened. What the flag does say is that the years disagree with each other by more than most of the state's do, so a single year of this series is a weak basis for a decision without the records behind it.

Compliance record

201 violations on EPA's record for this system as of 2026Q2. 198 resolved, 3 archived, 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.

Water balance, FY2024 · 17,500 MG system input
Billed 15,327 MG Unbilled authorized 217.5 MG Apparent loss 344.9 MG Real loss 1,611 MG

TWDB 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.

Balance closure is inapplicable on every filed year above, so the column that repeated it is not shown. TWDB derives water losses from system input minus authorized consumption, so this decomposition holds by construction. This is neither a pass nor a disclosure gap.

How much of this figure was measured

Apparent loss is three components: customer meter inaccuracy, unauthorized consumption, and data handling error. TWDB supplies a default value for the last two when a utility does not measure them, and records which in its export. Across the published record, unauthorized consumption is a default on 95% of filings, data handling error on 30%. The median filing is 14.4% defaulted, and 1,329 filings are more than half. TWDB's own data-validity score averages 68.4 out of 100 on the 9,315 filings using a default, against 70.0 on the 429 using none — so the score does not tell the two apart.

22.2% of Amarillo Municipal's reported apparent loss for FY2024 is a default rather than a measurement. How much of a Texas loss figure is measured sets this out across the whole filed record.

How the loss is valued

Apparent loss is water that reached a customer and was never billed: under-registering meters, data-handling errors, unauthorized use. It is valued here at the retail rate, because water that reached a customer would have sold at that rate. Real loss is valued at variable production cost only, since eliminating a leak saves what it cost to treat and pump the water rather than what it would have sold for. Valuing both at the retail rate is how a loss study produces a number nobody in a finance department believes, and that is the mistake this figure is built to avoid.

This is the value of the loss, not an amount anyone has established is recoverable. How much of it a utility can actually collect depends on which meters are under-registering, which accounts are unbilled, and what a replacement or an audit of those accounts would cost. None of that is in a filed water loss audit, and this page does not claim to know it.

Apparent loss is valued at this utility's own reported retail price of water, and real loss at its own reported variable production cost. Not our estimate, and shown to three significant figures.

Where is it going?

This page values the loss at roughly $2.6M a year. It cannot say which accounts, which zones, or which meters, and it cannot say how much of that value is collectable. Answering either 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.

Sources 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 looks wrong, tell us: the error may be in the filing, in our reading of it, or in something the export does not show. Send a correction. We will check it against the source, correct the page where it is wrong, and say what changed.
