What the filing says

Marlin serves 2,183 retail connections and about 5,653 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

66.4% non-revenue water in FY2021, higher than 99% of the 827 Texas systems that filed that year.

The reported figure is not stable enough to act on. It has moved an average of 15.9 points a year, against a Texas median of 5.79, including 63.1% to 26.0% between FY2016 and FY2017. 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.

Where is it going?

This page says how much — roughly $1.8M 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.
