Riyadh Southern Ring Water Project Named Best Infrastructure Project of the Year

The Riyadh City Southern Ring Water Transmission System has been named Best Infrastructure Project of the Year at the Construction Innovation Awards KSA 2026. The award recognizes infrastructure that strengthens water security and supports the Saudi capital’s continued growth.

Delivered under the supervision of the Water Transmission Company (WTCO), the system spans nearly 300 kilometers and can convey approximately 1.7 million cubic meters of desalinated water per day. This capacity supports the needs of communities, businesses and strategic developments, including Qiddiya.

Water infrastructure for a growing capital

Riyadh’s expansion places increasing demands on the infrastructure serving its residents and economy. Meeting those needs requires the capacity to move water where it is needed, alongside planning for future demand.

The Southern Ring Water Transmission System forms a critical part of the capital’s water network. By enabling the transfer of desalinated water across the city, it helps provide the supply capacity needed for new neighborhoods and economic development.

Khatib & Alami (K&A) provided design review and construction supervision for WTCO under a design-build contract, helping coordinate technical requirements and construction activities across the extensive network.

Coordinating complex works safely

A dedicated engineering team reviewed design submissions and resolved technical issues through regular coordination meetings, helping reduce rework and keep construction moving. On site, inspectors checked pipeline welds, internal coatings and cleanliness to verify construction quality.

Across works involving more than 2,000 people, the project recorded 5.6 million safe man-hours without a Lost Time Injury, marking a significant health and safety milestone.

“This recognition reflects the dedication of the people behind the project, who worked together to overcome challenges and deliver excellence for our partners,” said Maher Kahil, Vice President – Riyadh.

The award recognizes both the project’s engineering achievements and the collective effort behind infrastructure that supports Riyadh’s long-term water needs.
