Market Overview

The South Africa Study of Data Center Water Consumption Market has emerged as a critical focus area as the country rapidly expands its data center capacity to meet surging digital demand. Data centers are the backbone of cloud computing, telecommunications, artificial intelligence, and enterprise IT—but they are also significant consumers of resources, especially energy and water.

In South Africa, hyperscale operators, colocation providers, and enterprise-owned facilities are increasingly under pressure to balance performance with sustainability. With water scarcity being a national environmental challenge, data center operators are examining their cooling technologies, wastewater management, and overall water efficiency strategies.

Water consumption is closely tied to cooling systems (evaporative cooling, chillers, hybrid systems) that maintain servers at safe operating temperatures. The study of water consumption trends is now a central consideration for investors, regulators, and operators, influencing design choices, site selection, and sustainability reporting.

Meaning

The Study of Data Center Water Consumption Market refers to the analysis of how much water data centers in South Africa consume, what drives this consumption, and how it can be reduced.

• Direct Water Use: Primarily in cooling towers, humidification systems, and fire suppression.

• Indirect Water Use: Associated with electricity generation from power plants, as water is required for cooling in thermal energy systems.

• Water Usage Effectiveness (WUE): A key performance metric that measures the liters of water consumed per kilowatt-hour (kWh) of IT load delivered.

This market study encompasses technologies, operational strategies, and regulatory frameworks designed to optimize water efficiency while ensuring uninterrupted IT performance.

Executive Summary

The South Africa Data Center Water Consumption Market is gaining attention as both domestic and international operators expand capacity in hubs such as Johannesburg, Cape Town, and Durban. Valued at USD 12.5 million in 2024, the market for water-efficient technologies and monitoring systems in data centers is projected to grow to USD 21.7 million by 2030, at a CAGR of 9.1%.

Drivers include South Africa’s water scarcity, the rising carbon and water footprint reporting requirements, and the need for cost optimization in large-scale data centers.
