Why figures differ

How much water does the park treat?

Is it 192,000, 150,000 or 50,000 m³ a day?

Why the figures differ

These are three different measures. 192,000 m³ a day is the design capacity of the Water Treatment Complex, according to its designer Omrania. About 150,000 m³ a day is the treated wastewater volume Gerber describes, polished close to drinking quality. About 50,000 m³ a day is what MEED reported on 30 September 2026 for the plant now operating temporarily, which is about 26% of 192,000 and 33% of 150,000 (our arithmetic). A March 2024 MEED summary lists separate plant components too, including 160,000 m³ a day of treated sewage effluent, but that comes from a summary of a paywalled article and is worth checking.

What we show

All three values on the Water Treatment Complex page, each labelled as design capacity, treated volume or current temporary output. They are not shown as a conflict.

What would resolve it

Resolved as three measures. A single operating figure will be added once the permanent plant is running and the Foundation publishes it.
