How this atlas is made · What “last verified” means · What “source-checked” means · The full record behind this page

The towers of West Bay and The Pearl are cooled from plants run from one SCADA room, on sewage effluent instead of drinking water. The energy saving is the regulator's 30 to 40% estimate, not a measurement.

Qatar District Cooling Company (Qatar Cool) chills the towers of West Bay and the island development The Pearl-Qatar — both inside the Municipality of Doha — from central plants that pump chilled water through district networks, instead of every building running its own air-conditioning. Since September 2024 a command control centre at its West Bay plant uses SCADA and programmable logic controllers to monitor and control all its plants in both districts from one place, with real-time insight into plant efficiency, building operations and customer consumption. Customers are billed through thermal energy meters: smart metering at The Pearl goes back to a project begun in 2009, and in January 2023 Qatar Cool upgraded its Itron meter-data management system and contracted 25,000 more Itron meters. The water side is the unusual part: West Bay plants one and two were retrofitted in 2015 to run on 100% treated sewage effluent (TSE), the third West Bay plant has an in-house reverse-osmosis unit fed with TSE, and the two Pearl plants make their water from the sea by reverse osmosis.

📊 Impact

Qatar Cool reported in August 2017 that moving West Bay's two operating plants from potable water to TSE — blended in gradually over 1.5 years — had cut potable water use by 1.7 million cubic metres in 18 months. On energy there is no published measurement of this network: the figures are the regulator's general ones, with Kahramaa saying district cooling can cut electricity consumption by 30 to 40% compared with conventional air-conditioning and counting around 70 district cooling plants in Qatar. In 2026 the regulator added decisions designating district cooling service areas and governing network access to public land, and Qatar Cool continues to run both districts.

🎓 Lesson

In a desert city the binding constraint on district cooling is water as much as electricity, and it took the regulator to settle it: Qatar Cool says its West Bay plants switched to TSE in 2015 as part of a water scarcity resolution issued by Kahramaa, and Law No. 19 of 2024 now prohibits desalinated water for district cooling and makes a Kahramaa licence mandatory to operate a system. The energy case, by contrast, still rests on sector-wide percentages rather than a plant-level comparison anyone outside the operator can check.
