What the filing says
Moscow Water Supply Corp 1 serves 407 retail connections and about 962 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
70.8% non-revenue water in FY2015, higher than 99% of the 1,728 Texas systems that filed that year.
Compliance record
16 violations on EPA's record for this system as of 2026Q2, of which 3 are health-based. 11 resolved, 3 archived, and 2 still open.
- Public Notification Violation for NPDWR Violation unaddressed, from April 16, 2026
- Public Notification Violation for NPDWR Violation unaddressed, from May 15, 2025
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.

Notes on individual filings
TWDB records problems and granted waivers against a filing in its own export. Where we have found something it does not flag, that is stated here too, in full.
- FY2015. The filing states a retail price of $45.00 per thousand gallons. Filed retail prices outside $1 to $40 are not published here, so that price and TWDB's cost of apparent losses computed from it are both omitted.
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.
3.3% of Moscow Water Supply Corp 1's reported apparent loss for FY2015 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 at the TX median retail rate of $4.75/kgal, the median of 9493 rates filed by TX utilities themselves (2015–2024); real loss at $0.575/kgal variable cost. Substitute your own rate for an exact figure.

Where is it going?
This page values the loss at roughly $41,700 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.
