Cape Town Data Centre Plan Faces Water, Power And Environmental Questions

Cape Town’s push to attract major digital infrastructure investment is facing a difficult planning test after a proposed Equinix data centre development drew formal objections over its expected power demand, water use, emissions, diesel backup systems, noise impact and the level of information supplied to city planners.

Cape Town’s ambitions as a digital infrastructure hub are now facing a major environmental and planning test, after a proposed data centre development linked to global technology company Equinix drew formal objections from civil society groups.

Reuters reported that Equinix, a United States-listed technology company, plans to build two data centres in Cape Town. The application has been challenged by the Housing Assembly, which represents more than 20 communities in the Western Cape, and Foxglove, a United Kingdom-based non-profit organisation. The two groups argue that the project should not move forward without fuller disclosure of its water, electricity and environmental impact.

The objection raises questions about what data centre development means for a city already balancing growth, water security, electricity reliability and environmental oversight. According to Reuters, the concerns include the proposed centres’ projected water use, electricity demand, emissions, diesel backup power systems, air pollution, noise and even the level of building detail supplied in the application.

Data centres are not ordinary commercial buildings. They are the physical backbone of the digital economy. Every cloud service, streaming platform, online payment system, artificial intelligence tool, business database and digital application depends on computing infrastructure somewhere. As more companies move services online and as artificial intelligence increases demand for computing power, cities around the world are being asked to host larger and more energy-intensive digital facilities.

That is why the Cape Town proposal carries wider significance. It is not only a property or planning story. It is a question about how Cape Town wants to grow its digital economy, and what environmental safeguards should apply when that growth places additional pressure on power, water and surrounding communities.

Reuters reported that the proposed two data centres could have a combined projected power usage of up to 160 megawatts. That figure places the project in a category that requires careful public scrutiny, especially in a country where electricity security remains a constant concern for households, businesses and investors.

Water use is another sensitive issue. Cape Town’s 2017 to 2018 drought and “Day Zero” crisis remain fresh in the city’s public memory. Any large development that may require significant water for cooling, operations or fire systems is likely to face public questions, particularly when residents and businesses have already lived through water restrictions and the threat of severe scarcity.

Foxglove co-executive director Rosa Curling told Reuters that there was “simply not enough information” for a decision on a project of this scale, citing missing detail on water use, emissions, electricity demand, diesel generators, air pollution, noise and building information.

Saadiyah Kwada, an attorney at the Legal Resources Centre in Cape Town, also told Reuters there appeared to be a rush to develop data centres without enough consideration of their impact. Her comments point to a wider planning concern: cities may want technology investment, but communities want proof that major infrastructure will not shift hidden costs onto the public.

Equinix declined to comment to Reuters on the objection. Reuters also reported that King Air Industrial, linked to the King David Golf Club as the development site owner, declined to comment. The owners of the development site and Equinix have 30 days to respond to the objection, after which the City has 180 days to make a decision.

The City of Cape Town has not made a final decision. Deputy Mayor and Mayoral Committee Member for Spatial Planning and Environment Eddie Andrews said the City still needed to evaluate the application along with all comments and objections received from internal and external departments as well as interested and affected parties. He said the City could not comment further while the application was still being processed.

For Cape Town’s business community, the issue cuts both ways. Data centres can support cloud services, online commerce, financial technology, artificial intelligence development, business continuity and international investment. They can also help position Cape Town as a more serious digital economy player, especially if they attract related industries, skilled jobs and enterprise services.

But the concerns cannot be brushed aside. If a major data centre needs large amounts of electricity, backup diesel generation and water-dependent cooling, the public has a legitimate interest in knowing how those systems will work, what safeguards will apply, and whether communities nearby will face noise, air quality or infrastructure impacts.

This is where the Cape Town debate becomes commercially important. The city wants investment, but investment now carries a stronger trust test. Developers, planners and public officials must show not only that projects can create economic value, but that they can operate responsibly within local infrastructure limits.

For investors, the lesson is clear: environmental disclosure is no longer a side issue. In Cape Town, any large technology or infrastructure project will likely face sharper questions about water, power, emissions, resilience and community impact. Projects that answer those questions clearly may have a stronger path to public support. Projects that leave gaps may face delays, objections and reputational risk.

The Equinix proposal is now more than a data centre application. It has become a test case for how Cape Town balances digital growth with resource pressure, environmental governance and public accountability.
