The DGDA – Samhan Heritage Hotel wastewater treatment project by GI Aqua Tech represents a perfect fusion of advanced environmental engineering and cultural preservation. Situated in the heart of historic Diriyah, this project required a discreet yet high-performance solution that would safeguard the area’s heritage character while delivering world-class wastewater management.

To achieve this, GI Aqua Tech designed and implemented a fully integrated, medium-sized underground treatment plant based on proprietary G.NANO technology. The system operates silently, with zero odor emissions, and produces 100% reusable water supporting irrigation, landscaping, and other non-potable uses in alignment with Saudi Vision 2030’s sustainability goals.

The plant’s underground configuration ensures it remains invisible to hotel guests and blends seamlessly into the surrounding architecture, preserving the authentic charm of the Samhan Heritage Hotel and its environment. Its modular, scalable design allows for future capacity upgrades without increasing land footprint, ensuring long-term adaptability to the hotel’s operational needs.

With low power consumption, minimal sludge generation, and full compliance with strict environmental regulations, this project sets a benchmark for sustainable hospitality infrastructure. It showcases how modern wastewater treatment can be implemented in culturally sensitive locations without compromise protecting natural resources, enhancing operational efficiency, and reinforcing Diriyah’s status as a world-class heritage destination.
