Harris County MUD 372

What Harris County MUD 372 filed with TWDB about the water it produced and the water it billed for, 2020–2020 — and what the filing does and does not let anyone verify.

What the filing says

Harris County MUD 372 serves 1,571 retail connections and about 2,607 people. Because it reports fewer than 3,300 connections, it is on a five-year water loss audit cycle with TWDB.

What the record shows

13.2% non-revenue water in FY2020, higher than 38% of the 1,775 Texas systems that filed that year.

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.

Water balance, FY2020 · 193.6 MG system input
Billed 168 MG Unbilled authorized 2.42 MG Apparent loss 3.91 MG Real loss 19.3 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.

12.4% of Harris County MUD 372's reported apparent loss for FY2020 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 $75,800 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.

We will check it against the source, correct the page where it is wrong, and say what changed.
