What the filing says

Harris County WCID 91 serves 1,009 retail connections and about 3,027 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

37.4% non-revenue water in FY2024, higher than 84% of the 908 Texas systems that filed that year.

The reported figure is not stable enough to act on. It has moved an average of 19 points a year, against a Texas median of 5.79, including 3.7% to 37.4% between FY2020 and FY2024. A distribution system's real losses do not change that fast — pipe does not deteriorate or repair itself in a single year. A series that moves like this is describing how the water is being measured and recorded, not how much of it is being lost, and which year is closer to true cannot be settled from this filing.

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.
