• As a result of collaborative efforts between Veolia Water Technologies Qatar and Katara Project, the first water reuse facility of its kind in Qatar was built with a fresh water-saving capacity between 5 000 to 15,000 cubic meters per day.
• As part of its GreenUp strategic plan, Veolia contributes to fulfilling the goals of the Qatar National Vision 2030 strategy by reducing reliance on fresh water through the reuse of water for irrigation and as make-up water for district cooling.

Veolia Water Technologies (VWT) collaborated with Katara Project, to provide an innovative Treated Sewage Effluent (TSE) Polishing Plant. This project is marked as an achievement of an important milestone, which is aiming to fulfill the Environmental Development goals for Qatar National Vision 2030 strategy by conserving freshwater resources and promoting sustainable water use. 

Katara, a major cultural and touristic destination in Doha, will now save between 5,000 to 15,000 cubic meters per day (CMD) of fresh water previously used for irrigation and district cooling (cooling towers make up) by utilizing treated sewage effluent instead of desalinated sea or brackish water.

The TSE Polishing Plant, provided by VWT Qatar, is specifically designed to optimize space and power supply constraints within the existing Katara Energy Centre. This innovative approach has led to a significant reduction in project costs. The plant, with a capacity of 15,000 cubic meters per day (CMD), is the first of its kind in the region. It efficiently converts treated sewage effluent into high-quality demineralized water suitable for cooling towers feed and irrigation of Katara’s green hills. 

By substituting fresh water from KAHRAMAA with treated sewage effluent, the project reduces water costs dramatically — from 9 QAR down to 1 QAR per cubic meter, and reduces the power needed for water production to just 20% of that required for other treatment solutions. It also reduces the quantity of water used to feed the cooling towers.

This project exemplifies sustainable wastewater reuse, preserving groundwater resources and   consuming less energy. Veolia’s inline design technology, employed in this plant, represents a groundbreaking solution for wastewater reuse in the region. 

In June 2024, Katara Project enlisted Veolia Water Technologies Qatar in the further support with supervising the operation & maintenance of the plant.
