In a country this dry, losing 45% of the water is the most expensive problem there is.
Botswana's headline water problem isn't only scarcity — it's that around 45% of what's produced never earns revenue by WUC's August 2026 reporting, lost to leaks, theft and metering inaccuracy. Every lost megalitre here was pumped hundreds of kilometres down the North-South Carrier or lifted from a wellfield — the most expensive water in the region to waste. addanode builds the loss-visibility layer: district metering, night-flow analysis, wellfield-to-town balances and pressure monitoring, on infrastructure designed for long distances and remote sites.
Three loss problems a water-scarce system can't afford.
Long transfers, unmetered arrivals
Water that travels the Carrier or a wellfield collector main passes many places where it can leak or be drawn unmetered. Bulk meters at transfer points — telemetered, reconciled section by section — show exactly which stretch loses what, turning a system-wide percentage into a maintainable pipeline ledger.
Night flow no reader will ever witness
The 2–4am inflow into a town or zone approximates its leakage and unauthorised draw — the strongest leak indicator there is, and structurally invisible to manual reading. Telemetered zone inlets watch it every night, and a rising trend flags a new leak long before it surfaces in the sand.
Scarcity decisions made on estimates
Restrictions, rationing and augmentation planning all hinge on knowing real consumption versus real losses per zone. Continuous zone data replaces estimated splits with measured ones — so restriction regimes target actual waste, and capital cases for new sources rest on evidence.
Built for Botswana's geography.
- Distances are the defining constraint. Wellfields, transfer stations and villages sit hours apart; driving to read meters is the costliest data collection on earth. Solar-powered telemetry over 4G or private LoRaWAN — with satellite backhaul where truly remote — replaces the bakkie run with a dashboard, the same architecture as our remote site monitoring.
- The smart prepaid rollout changes the data landscape. With tens of thousands of smart prepaid meters going into Gaborone, consumption-side data is arriving. Zone inlet telemetry is its necessary partner: vends versus inlet flow splits commercial from physical losses cleanly — see prepaid verification.
- Groundwater needs balancing, not just pumping. Wellfield abstraction against delivered volumes, borehole by borehole, protects both the resource and the revenue — and documents sustainable yield for the regulator and planners.
- Power interruptions must not hole the record. Monitoring nodes buffer through BPC load shedding on battery and solar, so the night-flow history stays continuous.
Sector figures come from published Botswana reporting. The deployment pattern is our Southern African utility build, natively suited to Botswana's distances.
From wellfield to zone, one ledger.
1 · Meter the sources
Wellfield boreholes and transfer offtakes telemetered — production and conveyance become measured numbers.
2 · Zone the towns
DMA inlet meters and key pressure points per town and zone, solar-powered, buffered, long-range connected.
3 · Rank & act
Night-flow league tables and section balances route crews to the worst losses first — pipeline stretch or town zone alike.
4 · Prove it
Recovered megalitres documented per intervention — the evidence for boards, ministry reporting and the next zone's budget.
First deployment typically live in 2–6 weeks on the addaNet platform, beside water telemetry where asset monitoring is wanted on the same schemes.
Botswana's water numbers, and what zone measurement adds
| Indicator | Figure | What it means for measurement |
|---|---|---|
| Non-revenue water (WUC) | ~45% (WUC results briefing, Aug 2026) | In a water-scarce country, half the water pumped hundreds of kilometres is never billed |
| Prepaid smart meters, Gaborone | 35,000 in phase one (P500 million, announced 2024) | Collections improve; losses are found by zone balances, not customer meters |
| North-South Carrier | Strategic pipeline over hundreds of kilometres | Every transfer point is a balance boundary |
| Scheduled supply cuts | Rotational supply restrictions by area | Reservoir levels and zone inlets show which cuts are supply and which are loss |
Where loss data earns its keep in Botswana.
The national utility and its regions — zone and conveyance balances that make a 45% national figure locally actionable · District councils and village schemes — standpipe-era systems where every unbilled kilolitre strains a small budget · Mines and their towns — operations around Jwaneng, Orapa and the copper belt reconciling bulk supply with township distribution · Agriculture and lodges — borehole-dependent operations balancing abstraction against use across huge properties.
Non-revenue water in Botswana — common questions
How bad is non-revenue water in Botswana?
WUC's August 2026 results briefing put losses at an average 45% of production — leaks, theft and meter inaccuracy combined — against the World Bank's reference points of about 15% for developed-country utilities and 35% for developing ones. In a country that pumps water hundreds of kilometres and mines it from wellfields, the unit value of each lost megalitre is among the highest in the region.
Where do we start on a system this spread out?
At the balance points: wellfield outputs, Carrier offtakes and town inlets. A handful of telemetered bulk meters at those points typically explains more of the loss picture than hundreds of consumer meters — and tells you whether the problem lives in conveyance, in town zones, or in metering.
Does the smart prepaid rollout make this unnecessary?
The opposite — it completes it. Prepaid meters record vends; zone inlet telemetry records deliveries. The difference between the two is your physical loss and bypass figure, zone by zone. Consumption-side data alone can't see a trunk leak; inlet data alone can't see meter drift. Together they close the balance.
Can you monitor wellfield boreholes with no coverage?
Yes — private LoRaWAN gateways or satellite backhaul cover wellfields beyond mobile networks, with solar-powered nodes running for years unattended. Abstraction, levels and delivery reconcile automatically, and dry-run protection guards the pumps as a side effect.
What does a deployment cost?
It scales with balance points and zones, quoted as a written cost band after a free remote assessment of your scheme map. Given what conveyed water costs in Botswana, a single found trunk leak routinely repays the instrumentation that found it.
Who installs and maintains it across these distances?
Your technicians or local partners install pre-configured hardware under our remote guidance; solar power, multi-year batteries and remote diagnostics then keep healthy sites visit-free. The design goal is exactly zero routine trips.
