What the filing says
West Harris County MUD 4 serves 571 retail connections and about 1,713 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
10.5% non-revenue water in FY2021, higher than 27% of the 827 Texas systems that filed that year.
The reported figure is stable, moving 1.65 points a year against a Texas median of 5.81, 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.
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.
