Which 1,000 customer meters should I replace first, and what would be the return in 12 months?
Ranked by **measured error × volume**, not by age: about **€78.6k a year**. Replacing the **oldest** 1,000 instead returns only **€6.7k**. Sorting by age in this case leaves over 90% of the value on the table.
Ranked by **measured error × volume**, not by age: about **$85k a year**. Replacing the **oldest** 1,000 instead returns only **$7.2k**. Sorting by age in this case leaves over 90% of the value on the table.
Which leaks are being missed by my alarms, and where should the crews go tomorrow?
Two zones have a minimum night flow over **20× their target** and **no event open**. Ranked, they should be the targets for tomorrow. Nobody is looking at them yet.
I can afford renewing 20 km of pipe this year. Where would it avoid the most breaks?
Choosing by **predicted break rate** avoids about **1,200 breaks** in 10 years. By recorded breaks, only: **680**. By picking the worst asbestos cement: **600**. The same 20 km, up to twice the return.

Where would pressure management lower my losses the most?
It crosses the **simulated pressures of your hydraulic model** with **measured real losses** and your **existing PRVs**. Ranked by severity: {{Zone ; Pressure p95 (m) ; Real losses (l/conn/day) ; PRV // Zone 1 ; 78 ; 412 ; No // Zone 2 ; 71 ; 365 ; No}} The first two combine high pressure, high losses and no PRV: that is the pressure-management case. Model results are labelled as simulated, never passed off as measurements.

Build my 2024 water balance and tell me what the real losses cost me in that year.
Done on the **IWA balance** from your own components: **ILI of 13.8**, the cost of real losses and the actions that matter most. If the numbers don't add up, e.g. consumption is above system input, it tells you instead of reporting them.
