The verdict in three sentences
For a water services operator or funder managing 420 solar-pump boreholes in rural West Africa from London, a maintenance tracking app costs 10 to 22 million FCFA (about 13,000 to 28,500 GBP) and ships in 3 to 5 months. It combines an offline app for field technicians, SMS pump telemetry and dashboards for municipalities and donors. The realistic goal is to cut average downtime from 12 to 4 days, which changes daily life for whole villages and the operator's revenue collection.
Why the app must be built for field conditions
In the Koulikoro, Ségou or Sikasso regions of Mali, 3G coverage is patchy and many boreholes can only be reached by SMS. A standard app that needs a permanent connection fails within weeks. The specification therefore imposes three choices: offline data entry with deferred sync, pump alerts over SMS (2G is enough), and a French interface with pictograms for technicians who are not all comfortable with written text. The London team gets an English dashboard.
| Module | Scope | Indicative budget (2026 order of magnitude) |
|---|---|---|
| Offline technician app (Android) | Borehole records, preventive checklists, photos, water committee sign-off | 2.8 to 5.5M FCFA (3,600 to 7,100 GBP) |
| SMS telemetry | SMS gateway, flow reading, panel voltage, pump stop alarm | 2.0 to 4.5M FCFA (2,600 to 5,800 GBP) |
| Parts and stock management | Inverters, drives, cables, in and out per store | 1.5 to 3.0M FCFA (1,900 to 3,900 GBP) |
| Per-borehole history | Breakdowns, visits, repairs, pumped volumes, cumulative cost | 1.2 to 2.5M FCFA (1,550 to 3,250 GBP) |
| Municipality and donor dashboards | Functionality rate, repair times, PDF and Excel exports | 1.5 to 3.5M FCFA (1,900 to 4,500 GBP) |
| Water payment (optional) | Orange Money and Moov Money collection per water point | 1.0 to 3.0M FCFA (1,300 to 3,900 GBP) |
The telemetry sensor itself is not included: a GSM module with meter costs 120,000 to 250,000 FCFA (155 to 325 GBP) per borehole, plus 1,500 to 3,000 FCFA of SMS plan per month. Many operators first equip the 80 to 120 busiest boreholes.
Before and after: what the app measures
| Indicator | Current situation | 12-month target |
|---|---|---|
| Time to detect a breakdown | 3 to 6 days (reported by the village) | Under 2 hours (SMS alarm) |
| Average downtime | 12 days | 4 days |
| Preventive visits completed | 35% of plan | 85% of plan |
| Parts stock-outs | 1 to 2 per month | Under 1 per quarter |
| Network functionality rate | 82% | 95% |
| Donor report preparation | 8 to 10 days per quarter | 1 day |
| Pumped volumes known | Estimated | Measured on equipped boreholes |
Donors (bilateral agencies such as FCDO programmes, climate funds, NGOs) increasingly require verifiable functionality data. A reliable dashboard makes funding renewals easier.
3 to 5 month schedule
| Phase | Duration | Deliverable |
|---|---|---|
| Scoping in Bamako and visit to 5 to 10 boreholes | 2 to 3 weeks | Technician journey, list of typical faults |
| Offline app prototype | 3 weeks | Field test with 4 technicians |
| Telemetry, stock and history build | 6 to 9 weeks | Full platform in staging |
| Pilot on 40 boreholes | 3 to 4 weeks | Adjustments, technician training |
| Rollout to all 420 boreholes | 2 to 3 weeks | Network imported, dashboards open |
Mini case study
Ruth, programme director at a London-based water charity funding an operator in Mali, oversees 420 boreholes. Each broken borehole deprives about 600 people of safe water and loses roughly 6,000 FCFA of water sales a day. With 25 breakdowns a month and 12 days of average downtime, the loss reaches 25 x 12 x 6,000 = 1,800,000 FCFA a month. Dropping to 4 days brings it to 600,000 FCFA, so 1,200,000 FCFA (about 1,550 GBP) recovered each month. The app is quoted at 16 million FCFA, plus 100 boreholes fitted with telemetry at 180,000 FCFA, for 18 million FCFA (about 23,300 GBP), and 350,000 FCFA a month for hosting and maintenance. Net savings of 850,000 FCFA a month pay back the project in about 21 months on water sales alone, before counting secured donor funding and technician trips avoided.

FAQ
How much does a borehole maintenance tracking app cost in 2026?
Budget 10 to 22 million FCFA (about 13,000 to 28,500 GBP) for the app, SMS telemetry and dashboards. A first version without telemetry or payment starts around 7 million FCFA (9,000 GBP).
Does the app work without network coverage?
Yes, technicians log visits, faults and photos offline. Data syncs as soon as 3G or Wi-Fi is available, sometimes once a week when back at base.
What hardware is needed on the boreholes?
A GSM module with flow meter and voltage reading, 120,000 to 250,000 FCFA (155 to 325 GBP) per borehole. It sends an SMS alert when a pump stops and a daily volume reading.
Can municipalities and donors view the data?
Each municipality gets access limited to its boreholes, each donor to its programme. Quarterly reports export to PDF or Excel in minutes, in English or French.
What does it cost to run after launch?
Plan 250,000 to 450,000 FCFA (325 to 580 GBP) a month for hosting, SMS gateway and corrective maintenance, plus 1,500 to 3,000 FCFA of SMS plan per equipped borehole.
