Cape Town's planning system approved two Equinix data centres without public figures on how much water and electricity they would use. That omission is the real story behind the campaign against the project, and it argues for disclosure rules rather than the national moratorium some campaigners want.
What actually happened
On 17 September 2026, Rest of World reported that the Housing Assembly, a Cape Town advocacy group, and the UK nonprofit Foxglove are contesting Equinix's proposed 174-megawatt data centres. The reporting cites expected water use above 4.4 billion litres a year, which Rest of World equates to roughly 18,000 homes. The groups want water and electricity disclosure, community benefits, and a moratorium on hyperscale expansion.
The procedural facts are narrower than the headline suggests. Cape Town's Municipal Planning Tribunal approved the application on 14 July 2026. According to AllAfrica, the Housing Assembly and Foxglove, represented by the Legal Resources Centre, lodged a formal internal appeal on 6 August. That appeal legally suspends the approval. This is a municipal planning appeal, not a court case. Reporting also differs on scale: Rest of World says 174 MW, while Engineering News reported a combined projected draw of up to 160 MW. Neither figure appears to come from a published environmental assessment, which is the point of the dispute.
The strongest case for the objectors
The objectors' argument deserves a fair statement. Cape Town came close to losing its municipal water supply in the 2017-2018 "Day Zero" drought, as Engineering News notes. The Constitution guarantees everyone a right to an environment not harmful to their health or wellbeing, access to sufficient water, and access to information held by the state (sections 24, 27 and 32). The groups say the application contained "no substantive detail on water use, emissions, electricity demand, diesel generators, air pollution, noise or even the buildings themselves." If true, a permanent land-use right was granted before the public could test the numbers.
AllAfrica adds a structural problem. The tribunal granted rezoning and bulk reallocation on a 327,000 m² site, and those permissions attach to the land. Equinix says it has "no immediate plans to develop the site," but zoning that outlasts any one project's plans is exactly where scrutiny matters most.
Why a moratorium is the wrong remedy
Housing Assembly chair Kashiefa Achmat told Rest of World the group wants a moratorium "across South Africa." That is disproportionate, for three reasons.
First, the scale is not what the rhetoric implies. Rest of World reports that African data centre capacity is about 409 MW, under 1% of global capacity. McKinsey projects continental compute demand reaching 2.2 GW by 2030, around five times current levels. Demand growth of that kind will be served somewhere. A South African freeze would not remove it. It would push workloads to foreign facilities and weaken local cloud, financial-services and AI sectors.
Second, a blanket freeze treats a desert-edge solar-cooled site and a water-intensive one identically. Impact depends on cooling technology, power sourcing and location, and these are measurable.
Third, existing policy already points toward a more targeted approach. The National Data and Cloud Policy, published in Government Gazette 50741 on 31 May 2024 and summarised by ENSafrica, says data centres must be built and operated in line with environmental legislation and by-laws. It also says priority should go to self-provision of electricity and water, so that facilities depend less on national grids. In practice, the failure is that planning tribunals were not required to ask for numbers showing compliance.
A proportionate alternative
The planning statute already supplies much of the mechanism. Under section 51 of the Spatial Planning and Land Use Management Act, 2013, a person affected by a tribunal decision may appeal within 21 days, and the appeal authority must "confirm, vary or revoke the decision." The Cape Town appeal is that mechanism working as designed. Its likely outcome is a remand or conditions, not a ban.
The City says it is formulating refined development guidelines for large data centre applications, according to Deputy Mayor Eddie Andrews. That is the right venue. A sensible rule set would have five elements:
- Disclosure at application stage: projected annual water and electricity use, backup generator capacity and cooling design, published before a decision rather than at later approval stages.
- Water-source conditions: a preference for treated effluent or closed-loop cooling over potable supply, with consumption caps tied to municipal drought status.
- Power sourcing: on-site or contracted renewable supply, which also reduces strain on the grid.
- Reporting: annual public reporting of actual consumption against projections.
- Community benefit agreements: negotiated case by case, not imposed as a flat levy that deters investment.
This is also better for operators. Equinix says sustainable design is "a starting point." Hyperscale investors need predictable approval rules, and a clear disclosure standard offers that more reliably than a fight over each project. The City has said further technical infrastructure details will come at later approval stages. That sequencing is the flaw, because the permanent land-use rights are granted first and the data arrive afterwards.
A note on scope
This dispute is about land use, water and power. It is not, on the available evidence, about biometric surveillance or telecoms licensing, and no regulator beyond the municipality has been reported as central to it. Reading it as anything else would overstate what the sources show.
Bottom line
The Housing Assembly is right that a decision of this size should not be made without public figures. It is wrong to conclude that all hyperscale development should stop. South Africa can keep investment and protect scarce water by requiring disclosure before rezoning, tying approvals to measurable resource conditions, and letting the existing appeal process correct weak decisions. Cape Town's pending guidelines are the test of whether it does.
