Details of the Project
The Ras Mohaisen Desalination Plant will have a capacity of 300,000m³ per day, providing a vital source of drinking water to the Makkah Al-Mukarramah and Al-Baha regions, benefiting approximately one million people. This large-scale project will include:

This project is part of a broader effort to meet the growing demand for water in Saudi Arabia, particularly in the regions around Makkah. The desalination plant will play a pivotal role in addressing water scarcity issues in the country and contributing to its sustainable development goals.
Joint Venture and Project Significance
The contract is awarded as part of a joint venture between L&T and Lantania of Spain, with L&T acting as the lead partner. This project is especially significant as it is the second desalination order that L&T has secured in Saudi Arabia recently, solidifying its position as a leader in water treatment solutions in the Middle East. The project classification, deemed a large order, falls within the category of projects valued between ₹2,500 crores and ₹5,000 crores.
This strategic win underscores L&T’s expanding influence in international markets, particularly in the Middle East and other business-conducive geographies. The company is continuing its efforts to enhance its regional footprint and extend its leadership in the water treatment industry.

The Ras Mohaisen Desalination Plant project is a prime example of L&T’s strategic vision to lead in global water treatment and effluent treatment projects.
Impact on the Region
Once completed, the Ras Mohaisen Desalination Plant will provide a sustainable and reliable source of drinking water to the Makkah and Al-Baha regions, improving the quality of life for residents and addressing water scarcity in these areas. This initiative reflects the ongoing efforts of both L&T and ACWA Power to contribute to Saudi Arabia’s Vision 2030, a comprehensive plan aiming to enhance the kingdom’s infrastructure and diversify its economy.
