5 Theme of PKC Water Reclamation & Reuse The Development of Water Reuse Industry & the Innovation of Revolutionized Scientific & Practical Solutions for Efficient & Economic Utilization of Wastewater

6 PKC Vision Achieve National & International Leadership in the Research Realm of Advanced Wastewater Treatment Technologies & Water Reuse so as to Conserve & Develop the Kingdom Water Resources

7 PKC Mission The PKC has a threefold mission: Promote the reuse of wastewater for a wide variety of potential applications that suit our arid environment through education and scientific research on wastewater reuse, and disseminating awareness for the significance of reclaimed water as a strategic water resource. Development and implementation of innovative wastewater reclamation technologies that conform to local environment and resources. Build and maintain a broad and active network of local and international water-reuse researchers and professionals in academia, government, and the private sector.

21 Saudi Arabia Average Rainfall: 110 mm/ year Rainfall in south western region mm /year

22 Quantity of Reused Water In KSU 6,000,000 5,000,000 4,000,000 m 3 /day 3,000,000 2,000,000 1,000,000 24% 24% 0 Potable Water Collected & Treated Wastewater Reused Wastewater Quantity 6,000,000 2,800, ,000

23 Distribution of Wastewater Collected & Treated (2.8 million m 3 /day) According to Regions Eastern Region 34% Riyadh Region 26% 24% Other Regions (10) 18% Makkah Region 22%

24 Uses of Reclaimed Water in SA Other Purposes 25% Industrial (cooling, processing,...) Stream Flow Augmentation Irrigation 75% Agriculture Irrigation Landscape irrigation

25 Water Reuse for Agriculture Irrigation in Riyadh (200,000 m3/day)

26 Wadi Hanifa (Riyadh) Wadi Hanifah is the main drainage for the city. 120 km from the northwest to the southeast of Riyadh square km catchment basin. 60% of the developed area in city inside it catchment. Current Flow = 450,000 m3/day
