- Recoverable annually
- $2,558 As computed in the filed audit itself: apparent loss valued at this utility's own reported retail price of water, real loss at its own reported variable production cost. Not our estimate.

- closed The filed water balance closes.
What the filing says
Markham MUD serves 460 retail connections and about 1,400 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
9.6% non-revenue water in FY2024, higher than 20% of the 908 Texas systems that filed that year.
- The figure is improving across the record.
The reported figure is stable, moving 7.17 points a year against a Texas median of 5.79, so the level is more likely to reflect the system than the paperwork.
Components sum to within 0.00% of reported system input, inside the 0.5% tolerance.

How to read the recoverable figure
Apparent loss is water that reached a customer and was never billed — under-registering meters, data-handling errors, unauthorized use. It is valued at the retail rate, because recovering it is revenue, and it is recoverable inside a budget year without capital work. Real loss is valued at variable production cost only: eliminating a leak saves what it cost to treat and pump the water, not what it would have sold for. Adding those two at the same rate is how a loss study produces a number nobody in a finance department believes.

Where is it going?
This page says how much — roughly $2,558 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.
