million gallons of estimated physical leakage
UTILITY PROFILE / CATOOSA
Catoosa Utility District
Catoosa County audit grouping. Ten-year reporting period: 2016–2025. Latest audit: 2025. Annual estimates help identify questions about infrastructure and spending.
What the utility reported
In 2025, Catoosa Utility District supplied 1,837.4 million gallons and reported 230.3 million gallons lost, or 12.5% of supply. That equals 631,053 gallons per day.
million gallons of apparent losses
gallons of physical leakage / connection / day
Physical leakage changed -52.3% since 2024, -36.1% since 2020 and -35.9% since 2016. Total losses changed -51.0% in the latest year. Changes in meters, methods or audit boundaries can affect reported trends.
Reported by the utility / calculated from the audit 2025 EPD compilation, worksheet “2025 Water Audits ”, row 42. Definitions.
What deserves a closer look
Reported improvement needs supporting records
Estimated physical leakage fell from 456.0 to 217.7 million gallons (-52.3%). That establishes a smaller reported estimate. Meter verification, leak logs and audit notes are needed to establish how much reflects actual leakage reduction.
The population entry is 7,800 with 22,668 connections, compared with 60,000 people in 2024. Population does not enter the loss-balance calculation. The Infrastructure Leakage Index is 0.83. Below 1 warrants review, but does not automatically prove an error.
Physical and apparent losses over time
Reported water losses, 2016–2025
Compare the total gallons with the two types of loss. An apparent-loss revision can also change the residual physical estimate.

Compare more than one measure
A physical service connection is not necessarily one home or one bill. Main length, pressure, density and input quality differ across systems.
Where its water came from
| 2025 supply item | Million gallons |
|---|---|
| Own sources | 1,407.176 |
| Imported from other systems | 786.068 |
| Exported to other systems | 371.496 |
| Adjusted net water supplied | 1,837.374 |
Net supply accounts for exports and source-meter adjustments. Raw own-source and import values may not sum directly to adjusted supply. These audits cannot trace a particular leaked gallon to a particular source.

Where every 100 gallons went
Billed use, legitimate unbilled use, apparent losses and estimated physical leakage add up to supplied water. Firefighting and flushing mains are authorized uses.
Calculated from the selected audit. Physical leakage is the residual after authorized use and apparent losses, not a measurement of every leak. Non-revenue water also includes legitimate unbilled use.
Costs and infrastructure decisions
| 2025 financial field | Reported value |
|---|---|
| Physical-loss valuation | $142,020 |
| Apparent-loss valuation | $62,247 |
| Total estimated loss valuation | $204,266 |
| Physical-loss valuation basis | VPC |
| Variable production cost ($ / MG) | $652 |
| Retail charge ($ / 1,000 gallons) | $5.05 |
| Reported annual operating expense | $10,079,916 |
Physical leakage is typically valued at variable treatment, pumping and purchase costs. Apparent losses are usually valued at retail charges. The full valuation is not guaranteed savings. Project costs, fixed expenses and contract terms matter. Values are retained as filed; historical unit or basis changes limit comparison.
A loss-valuation/operating-expense ratio is withheld until the financial inputs and expense scope are reconciled. Dividing valuation by physical connections does not estimate an individual customer’s bill increase.

ILLUSTRATIVE SCENARIO
What would a leakage reduction avoid?
Test an assumed reduction and an independently chosen avoidable cost. These are hypothetical variable expenses before repair and program costs. No future rate reduction is predicted.
The default $1 is an illustration, not a utility cost estimate. Include incremental operating costs when assessing a real program. Fixed labor, debt and contracted purchase minimums may remain.

An unusual input warrants explanation, not automatic correction. The leakage index compares real losses with a theoretical reference based on pipes, connections and pressure. Respect applicability flags and inspect the underlying workbook before using it. How to evaluate audit quality.
