The disaster crisis demands better technology.

HazardZero Technology Ltd. was founded to bridge the gap between advanced technology and the communities that need it most. We build affordable, accessible, and resilient disaster intelligence and emergency technology solutions for communities across Africa.

+78%

Increase in severe flooding events in Nigeria over the last decade

$150B+

Estimated annual losses from floods across African economies

70%+

Of disaster-related deaths could be prevented with early warning systems

01

Annual floods destroy lives, homes, and farmlands across Africa.

02

Existing warnings often arrive too late or require internet access.

03

Rural communities are most vulnerable and least connected.

R!SEWATCH

Our flagship product — a solar-powered, offline-first flood early warning system that senses, thinks, and alerts — automatically. Built for Nigeria's most vulnerable communities.

R!SEWATCH flood early warning system device

Offline-First

Works without internet. Built for rural, disconnected communities.

Real-Time Sensing

Ultrasonic sensor measures water levels every minute.

Predictive AI

Rate-of-rise analysis delivers 1–3 hours of early warning.

Multi-Channel Alerts

Siren, lights, and SMS alerts reach everyone instantly.

Solar Powered

Runs entirely on solar energy for off-grid deployment.

Rugged & Reliable

Engineered to withstand harsh weather with minimal maintenance.

How R!SEWATCH Works

From sensor reading to community alert in four seamless steps.

01

Sense

Ultrasonic sensor measures water level every minute with high accuracy.

02

Think

Arduino controller analyzes rate-of-rise and threshold breaches.

03

Send

GSM module sends SMS alerts while local triggers activate in real time.

04

Alert

Siren and flashing lights warn the community instantly — no phone required.

Rate-of-Rise Prediction — Our AI Edge

Unlike traditional systems that use simple threshold alerts — which often arrive too late — R!SEWATCH stores the last 10 water-level readings with timestamps to calculate the speed of the rise.

Store 10 Readings

Every minute, a new reading is recorded with a timestamp.

Calculate Rise Speed

The system computes how fast water is rising over the recent window.

Predict & Alert Early

If speed exceeds the danger threshold, it predicts time-to-flood and sends an SMS.

The people building the future of resilience.

A dedicated team of engineers and innovators building climate resilience technology from within the communities most at risk.
