​​As part of its ongoing efforts to contribute to achievement of the goals of the Saudi Green Initiative (SGI), the National Water Company's (NWC’s) Northwest Cluster finished planting more than 2.1 million trees in multiple locations in the Madinah Region. The SGI initiative aims to develop vegetation cover, combat desertification, promote environmental sustainability, and increase the efficiency of using the triple-treated water outcoming from environmental treatment plants.

 
The company explained that its afforestation work planted in the Madinah region exceeded 472,000 trees in 2025, bringing the total since the initiative's inception to over 2.1 million trees. The company indicated that the afforestation work is proceeding according to an implementation plan that optimizes the use of treated water for environmental and quality-of-life benefits.
 
NWC stated that the afforestation projects covered several sites in Madinah, Yanbu, Badr, Al-Mahd, Khaybar, Al-Hanakiyah, Al-Ula, and Waha Abar Al-Mashi, including areas around environmental treatment plants (STPs). The company noted that the projects included planting various types of trees suitable for the region, such as kurz, sidr, salam, coastal khabeez, Indian almond, lemon, jahnamiya, takuma, acacia, basil, qatifa, bakhta, zout, kuf Maryam, neem, arsin, and makhala.
 
The company confirmed that more than 10% of the previously planted trees, exceeding 200,000, have become self-sustaining, eliminating the need for care and irrigation. NWC confirmed that they will continue to implement more afforestation projects during the appropriate agricultural seasons. They will also support plant cultivation initiatives and enhance integration with relevant entities, foremost among which is the National Center for Vegetation Development and Combating Desertification (NCVC), is part of its expansion plans to utilize treated water and contribute to achieving the objectives of SGI, including improving air quality, increasing oxygen levels, supporting biodiversity, reducing harmful environmental emissions, and increasing vegetation cover.​
