AOWIS – Afritic Open Standard for Water & Agricultural Infrastructure

AOWIS is an open technical standard for safe and reliable water and agricultural infrastructure, designed for low-resource environments.

It defines how systems are operated through sensors and actuators, either autonomously, manually, or in combination. AOWIS is designed to function under conditions such as unstable power, limited connectivity, and minimal technical support, supporting both online and offline operation.

Motivation

In less developed regions, such as rural areas and small towns in Africa, water distribution remains a significant challenge. While NGOs have been successfully supporting communities for decades by drilling wells, installing pumps, and sometimes building water towers, distributing water across a network on the surface is often difficult.

Local initiatives that take on these projects frequently encounter a situation where operating the system manually becomes unsustainable, requiring constant attention. Qualified personnel are scarce, and suitable technology to support automated or semi-automated operation is either unavailable under local constraints or too expensive.

This is where AOWIS aims to contribute: by providing an open standard for designing, deploying, and managing water and agricultural infrastructure in such environments. AOWIS supports both the planning phase—helping initiatives evaluate and design systems based on regional conditions such as topography—and the operational phase, including system monitoring, control, and maintenance.

In addition, AOWIS aims to support the training of local technicians and to collaborate closely with experienced NGOs and local initiatives that already operate and maintain such systems, in order to improve sustainability and reduce operational burden.

Operation Conditions of AOWIS

AOWIS is designed to operate under the real-world conditions faced by local initiatives. These include, among others:

• unreliable power supply
• intermittent connectivity
• diverse or aging equipment
• limited availability of trained personnel
• the need for safety and autonomous operation

AOWIS enables systems that continue to function safely and reliably, even under degraded or adverse conditions.

Why AOWIS Exists

Many communities rely on infrastructure that is fragile, manually operated, or dependent on unstable networks. AOWIS addresses this by defining:

• offline‑first operation
• human‑in‑the‑loop control
• safe fallback behavior
• modular, extensible logic
• shared infrastructure models
• transparent governance

The goal is to make essential systems **robust, maintainable, and locally operable**.

How AOWIS Works

AOWIS is built around a three‑layer control model:

• Field Controller – Local, autonomous, safety‑critical
• Farm Controller – Coordination, scheduling, logic
• HQ Controller – Oversight, reporting, governance

Core principles include:

• Offline‑first
• Measurement‑driven
• Fail‑safe by design
• Human‑operable at all times
• Modular and extensible
• Transparent and auditable
