Proposed Gauteng R22.6 billion Vaal airport: What locals need to know

If you’ve ever driven down the N1 past Vanderbijlpark and wondered what’s going to happen with all that open farmland, here’s your answer: an international airport.

The proposed Vaal Aerotropolis has moved a step closer to reality. Developer Vaal Aerozone is now applying for environmental authorisation for the first phase. The developer published its public participation notices on 30 September.

What’s actually on the table

The project is pegged at R22.6 billion, with R12.2 billion of that set aside for the airport itself. That’s according to the Sedibeng District Municipality.

It will sit in Emfuleni, about nine kilometres west of Vanderbijlpark, as part of the proposed Vaal Special Economic Zone (SEZ). The land covers parts of 13 farms, and Johannesburg is roughly 50 minutes away by road.

The airport is meant to start with room for 7.2 million passengers a year, plus 150 000 tons of freight. Phase one is also set to include a 4.2km runway, a cargo terminal and four freighter stands.

Around the runway, the plans include an airport city with offices, medical consulting rooms and a hotel with more than 90 rooms. There’s also a solar farm, a trade zone for manufacturing and distribution, and an agri-zone with climate-controlled greenhouses, packhouses and a tissue culture lab. The developer pitches that zone as an export platform for fresh produce, including live animals.

Jobs and the timeline

The numbers on jobs are big. Developers say construction could create 12,000 jobs, with another 6,000 permanent positions once the airport is running. For a region that has watched its industrial base shrink, that will catch attention.

If approvals come through, construction on phase one is planned for 2029 to 2031, with flights targeted for 2032. The full vision is far longer. The Vaal AeroZone project page sketches three phases, with the second and third pencilled in for 2048 and 2068.

This idea has been circling for years

This isn’t a brand-new announcement. The Vaal SEZ was first floated by then Gauteng Premier David Makhura in his February 2020 State of the Province address. In 2023, Citibank South Africa pledged about R1.4 billion towards the first phase, as Daily Investor notes. Joburg Etc first covered the Vaal River mega city plan back then.

Back in 2024, former Gauteng finance MEC Lebogang Maile spoke of total investment reaching R200 billion. Critics at the time pointed to King Shaka International Airport, which cost R6.8 billion to build, and questioned the scale of the Vaal numbers.

The questions locals are asking

Excitement and scepticism are both in the mix. At a Vaal SEZ engagement in Vereeniging in April 2026, residents raised concerns about Emfuleni’s unreliable water and electricity. Their worry is simple: can an area that struggles with the basics support a world-class aviation hub? Joburg Etc has reported on Emfuleni’s water and electricity problems before and the sewage crisis is another sore point for residents.

The licence of nearby Vereeniging Airport was also cancelled in April 2026, which only sharpens that question. Vaal Aerozone, for its part, calls the project ‘a key freight and logistics hub’ that will help revive Emfuleni.

Have your say before 2 December

This is the part that matters most for locals. Interested and affected parties can submit written comments to environmental assessment practitioner EMS Africa by 2 December 2026. Those comments will feed into the final scoping report that goes to the Gauteng Department of Environment.

A project this size doesn’t happen overnight, and plenty can change between now and 2032. But if you live, farm or work in the Vaal, this is your window to speak up.
