Diriyah Gate Sewage Treatment Plant (STP)
A 32 MLD sewage treatment plant in the heritage city of Diriyah, designed in the mandated Najdi architectural style.
Key figures
Overview
The project
Diriyah Gate STP in Saudi Arabia requires a sewage treatment facility with a nominal design capacity of 32,000 m³/day (32 MLD), plus an additional 10,000 m³/day (10 MLD) from tertiary polishing of district-cooling blowdown. The scope also includes five years of operation and maintenance after construction. WETICO is proposing FCR technology.
Diriyah is a heritage destination where the Najdi architectural style is mandated for every building in the city, including this project. The STP building design therefore follows the Najdi style, blended with the green aesthetic of the FCR technology.
