The verdict in three sentences
For a utility serving 180,000 accounts in the Miami area, a custom meter reading and billing system costs, as a 2026 order of magnitude, USD 1 to 3 million, depending on AMI integration, data migration from the legacy customer information system and the number of rate structures. The return does not come from technology itself but from measurable mechanisms: fewer estimated bills, recovery of apparent losses from under-registering meters and unbilled accounts, and faster leak and tamper detection. Under the AWWA water audit method, the system also becomes the backbone of your non-revenue water reporting.
Scope and cost
Non-revenue water combines real losses (network leaks) and apparent losses: meter inaccuracy, unauthorised consumption, unbilled accounts and data handling errors. Billing software acts mostly on apparent losses, which typically make up a quarter to a half of the gap in US utilities.
| Module | Key function | Indicative 2026 cost (USD) | Build time |
|---|---|---|---|
| Account and meter registry | Premises, meters, GIS links, pressure zones | 120,000 to 350,000 | 3 to 5 months |
| Meter reading | AMI head-end integration, mobile reads with photo for manual routes | 150,000 to 450,000 | 3 to 5 months |
| Billing engine | Tiered water, sewer and stormwater rates, adjustments, disputes | 250,000 to 700,000 | 5 to 8 months |
| Payments | Cards, ACH, autopay, IVR, payment portal | 80,000 to 200,000 | 2 to 3 months |
| Anomaly detection | Continuous flow leak alerts, zero use, reverse flow, tamper flags | 120,000 to 350,000 | 3 to 4 months |
| Collections | Reminders, payment plans, shutoff and restoration orders | 80,000 to 250,000 | 2 to 3 months |
| NRW reporting | AWWA water audit, district metered area balances, dashboards | 60,000 to 200,000 | 2 months |
Modules total USD 860,000 to 2.5 million before data migration, parallel billing runs and staff training. Annual running costs (hosting, maintenance, SMS and email notices) represent 10 to 15% of the build.
Customer leak alerts change the relationship with residents: AMI data flags continuous flow within 24 to 48 hours, and a text message prevents a USD 600 bill and the dispute that would follow. Billing complaints fall quickly, and so do courtesy adjustments.
Expected gains
Assumptions: 180,000 accounts, average combined bill of USD 65 a month, about USD 140 million billed a year, 96% collection rate, non-revenue water at 20%.
| Indicator | Current situation | 24-month target |
|---|---|---|
| Estimated bills | 6% | below 1% |
| Read-to-bill delay | 10 days | 2 days |
| Collection rate | 96% | 97.5% |
| Autopay and online share | 45% | 70% |
| Billing disputes | 2% of bills | 0.8% |
| Stuck or under-registering meters found | during periodic testing | every month |
| Non-revenue water | 20% | 16 to 17% |
Each 1% of additional billed revenue is worth about USD 1.4 million a year. Recovering apparent losses increases billed volumes without producing an extra gallon.
Deploy by pilot districts
A realistic rollout starts with two or three representative district metered areas, for example a residential zone and a commercial corridor, covering 15,000 to 20,000 accounts. Measure the district water balance before and after, tune anomaly rules, then extend in waves of 30,000 to 40,000 accounts. Running the legacy and new billing in parallel for two cycles is the safest way to protect revenue during cutover.

Carlos, customer service director of a water utility serving 180,000 accounts in South Florida, approves a USD 1.8 million project with USD 250,000 a year in running costs. To stay prudent, he retains only a 1% increase in billed revenue in year one, from apparent loss recovery and fewer estimates: USD 1.4 million. Net gain: 1,400,000 - 250,000 = USD 1,150,000. The build is covered in 1,800,000 / 1,150,000 x 12 = about 19 months, before counting lower dispute handling costs and better collection.
FAQ
Do we need to replace every meter first?
No, the system helps target replacements. Anomaly detection usually flags 2 to 4% of stuck or under-registering meters within the first three months of AMI or photo-verified reads.
Can the system work with our existing AMI network?
Yes, it integrates with the head-end system through its API or file exports. Manual routes use a mobile app with photo capture, where a reader covers 300 to 500 meters a day.
How are payments reconciled?
Card, ACH and portal payments carry the account reference and post automatically. Unapplied payments, often 1 to 2% of manual receipts, drop close to zero.
What about unauthorised connections?
The system opens a case with photo, location and history, then triggers billing or enforcement. Converting an unbilled connection to an account adds about USD 780 of revenue a year at USD 65 a month.
How long for a first pilot district?
Plan 6 to 8 months for registry, reading and billing on 15,000 to 20,000 accounts. Extending to the full customer base then takes 12 to 18 months.
