Water telemetry in Botswana — in a country this dry, every borehole deserves a dashboard.
Botswana runs on groundwater moved over enormous distances — village borehole clusters, mine wellfields, farm and cattle-post boreholes, and transfer pipelines that carry water hundreds of kilometres between dams and cities. addanode telemetry puts tank levels, flow, pressure, pump status and power state on one dashboard, protects pumps from dry-running boreholes, and turns "drive out and check" into an alert that arrives before the tank is empty.
The problems every Botswana water operator recognises.
Boreholes discovered dry — or broken — too late
A failed borehole pump at a village or cattle post is found when the tank runs out, and the drive to confirm it can be half a day. Telemetry reports level, flow and pump status continuously, alerts on the trip, and — because drought draws water tables down — cuts the pump before dry-running destroys it. The drawdown record also shows what each borehole can sustainably give.
Long pipelines, blind between ends
Botswana's water travels — transfer schemes and trunk mains where a burst or a failing pump station shows up as a dry town days later. Pressure and flow monitoring along the line finds the abnormal drop when it happens and locates it to a segment, not a rumour.
Scarce water lost between pump and bill
In a country that imports rain by pipeline, non-revenue water is a scarcity problem before it is a revenue one. Continuous bulk-meter telemetry lets a scheme reconcile what each zone received against what was billed, and night-flow patterns expose the leaks no meter reader sees.
Engineered for Botswana's water infrastructure as it is.
- No coverage at the wellfield. Boreholes sit where cattle graze, not where towers stand. Where mobile coverage is absent we deploy private LoRaWAN — sensors talk to your own gateway over kilometres — with satellite backhaul for the deep Kalahari. Every device buffers locally either way.
- Solar is the power plan. Most remote boreholes pump on solar or diesel; monitoring hardware matches them — solar-charged, battery-buffered, designed for months between physical visits, with remote diagnostics and over-the-air updates instead of site trips.
- Heat, dust and distance. Equipment is specified for Kalahari summers and the corrugated roads between sites; installation is by your own technicians or local partners under remote guidance, with pre-configured hardware a day's drive from Johannesburg.
- Scheme budgets and procurement reality. Deployments start with one borehole cluster, one pipeline section or one problem village, priced as a written cost band after a free remote assessment. Existing meters, probes and starters are read rather than replaced — pulse, Modbus and 4–20 mA included.
Based on water-sector deployments across Southern Africa, this configuration is adapted for Botswana — distance, off-grid power and coverage holes included.
What a water telemetry rollout in Botswana looks like.
1 · Instrument
Level sensors in tanks and reservoirs, flow from existing bulk meters (pulse or Modbus), pressure transmitters along trunk lines, current and run-status on every pump — new sensors only where nothing exists.
2 · Connect
4G near towns; private LoRaWAN gateways at wellfields; satellite where truly remote. Solar-powered nodes as standard for off-grid sites; store-and-forward buffering everywhere.
3 · Protect
Dry-run protection cuts a pump before drawdown destroys it; alerts fire on abnormal pressure drops, empty or overflowing tanks, tripped pumps and power events at stations.
4 · Reconcile
The addaNet dashboard shows the whole scheme on one screen; bulk-meter and zone data export cleanly for input–billing reconciliation, NRW reporting and scheme records.
Typical first deployment: one borehole cluster or pipeline section live in 2–6 weeks — on the addaNet industrial IoT platform, alongside remote site monitoring for the rest of the site.
Botswana water assets and the sensors each needs
| Asset | Sensors | Constraint that decides the design |
|---|---|---|
| North-South Carrier and transfer stations | Flow at every transfer, tank levels, pump state | Hours between stations; a balance that must close remotely |
| WUC reticulation zone | Bulk input, reservoir level, DMA night flow | NRW ~45% (WUC, Aug 2026) — the zone is the unit of action |
| Wellfield | Abstraction meter, water level, pump current | Aquifer drawdown; no resident technician |
| Village standpipes | Tank level, delivered volume, heartbeat | Supply cuts — the community sees the dry tap first |
| Treatment works | Turbidity, chlorine residual, flow | BOS 32 drinking-water quality between lab samples |
Water operators we build for in Botswana.
Utility and government schemes — village supply clusters, wellfields and transfer infrastructure that need continuous data across districts · Mines and mining contractors — wellfield abstraction, dewatering, process water and camp supply, tracked with the same platform as plant assets · Farms, ranches and cattle posts — borehole, tank and trough monitoring across paddocks measured in hours, not hectares (broader assets? see remote site monitoring) · Lodges and camps — water security for operations where a dry tank means closed beds · Industrial users — Gaborone and Francistown plants tracking abstraction, storage and consumption alongside production monitoring.
Water telemetry in Botswana — common questions
Can you monitor a borehole in the Kalahari with no mobile signal?
Yes. A private LoRaWAN gateway — placed at the nearest point with power and backhaul, or connected by satellite where there is none — receives sensor data over distances of kilometres with no mobile operator involved. The sensors themselves run for years on batteries or solar, which is the norm for cattle-post and wellfield sites.
What is dry-run protection and why does it matter in Botswana?
Dry-run protection stops a pump automatically when water level or motor-current signatures show it is pumping air. Botswana's water tables draw down hard in drought, and a pump that keeps running against a falling level destroys itself — a replacement and a dry village that cost far more than the monitoring. The drawdown record also documents each borehole's sustainable yield.
How does telemetry help with non-revenue water?
It gives a scheme the numbers NRW work starts from: continuous input metering per zone, reconciliation against billing daily instead of quarterly, pressure data that shows where bursts and leaks concentrate, and night-flow patterns that expose losses invisible by day. In a water-scarce country the saved water matters as much as the saved revenue.
Can addanode read the meters and probes we already have?
Usually, yes. Pulse-output bulk meters, Modbus instruments, 4–20 mA level and pressure transmitters and pump starters are all standard inputs — among 500+ supported protocols. New sensors are added only where a site has nothing to read, which keeps the cost of instrumenting an existing scheme down.
Who maintains equipment at sites hours from anywhere?
Mostly nobody has to — that is the design goal. Solar power, multi-year batteries, remote diagnostics and over-the-air updates mean a healthy site needs no routine visits. When hardware does need hands, your own technicians or local partners handle it with our engineers guiding remotely on WhatsApp — and replacement units are a day's freight from Johannesburg.
What does water telemetry cost for a Botswana scheme?
It scales with sites and sensors, not with promises. A first deployment — one borehole cluster or one pipeline section — is quoted as a written cost band after a free remote assessment of your scheme layout and existing instrumentation. Starting with the worst cluster and scaling on evidence is the pattern that works.
