Wastewater recycling in the City of Riyadh, Saudi Arabia
Due to the huge growth of the Saudi Arabian capital, fresh water resources have become scarce. Fichtner has therefore been awarded a contract to prepare a master plan for the City of Riyadh with the aim of ensuring an effective and sustainable use of treated effluent and other sources of reclaimed water. Investigations were underway for reuse of this water primarily for agriculture, but for other purposes, too, like in industry or for irrigating greened areas. Also being studied was how groundwater reserves can be recharged with the treated wastewater.
