Industrial Cities in KSA Number of cities increasing Modon overseas 30 existing and developing cities Cities located near natural resources – locations can be very remote More than 3,00 factories in existing cities Courtesy of Fujitsu and MODON

Water Challenges in KSA Over 80% of water is withdrawn from non-renewable groundwater aquifers, estimated to contain only a 15-25 year supply of water

Water Challenges in KSA Only 65% of wastewater generate in the Arabian Peninsula is treated KSA target - by 2025, cities over 5,000 people should be reclaiming nearly 100 percent of their water Water currently is mainly reused for irrigation

Wastewater production, treatment and reuse in Saudi Arabia, 2009 Kajenthira, Arani, Laura Diaz Anadon, and Afreen Siddiqi.

Challenges for Industrial Cities high water demand for industrial processes secure supply required remote locations not connected to supply and distribution systems

Water Supply for Industrial Cities Options: Piped desalinated water Groundwater source Supply by tankers Challenges: Cost Lack of infrastructure Security of supply - essential

Water Supply for Industrial Cities Desalination options: - Reverse Osmosis Thermal Desalination Costs/challenges: Oil/gas use – water costs linked to commodity price Transportation – infrastructure and costs Feed water quality in Arabian Gulf

Wastewater Treatment for Industrial Cities Challenges: Cost Lack of infrastructure Final effluent and pollution of receiving waters (desalination concern)

Efficient Waste Solutions

Water Reuse Systems

Process Optimisation Options studies for industrial processes to improve potential for water reuse Close collaboration with operator to identify process change possibilities

Economic and Environmental Factors Kajenthira, Arani, Laura Diaz Anadon, and Afreen Siddiqi. "A New Case for Wastewater Reuse in Saudi Arabia: Bringing Energy into the Water Equation." Policy Brief, Belfer Center for Science and International Affairs, Harvard Kennedy School, June 2011.

Economic and Environmental Observations Typically for inland cities, the provision of desalinated water is more energy-intensive than the secondary or tertiary treatment of local wastewater Kajenthira, Arani, Laura Diaz Anadon, and Afreen Siddiqi.

Economic and Environmental Observations Thermal desalination, using fossil fuels, without cogeneration is never as economically competitive as Reverse Osmosis Kajenthira, Arani, Laura Diaz Anadon, and Afreen Siddiqi. "A New Case for Wastewater Reuse in Saudi Arabia: Bringing Energy into the Water Equation." Policy Brief, Belfer Center for Science and International Affairs, Harvard Kennedy School, June 2011.

Economic and Environmental Observations It is estimated that 29% of total industrial water withdrawls could be saved through water reuse, recycling and conservation methods Kajenthira, Arani, Laura Diaz Anadon, and Afreen Siddiqi. "A New Case for Wastewater Reuse in Saudi Arabia: Bringing Energy into the Water Equation." Policy Brief, Belfer Center for Science and International Affairs, Harvard Kennedy School, June 2011.

Economic and Environmental Observations It is estimated that 26% of urban water needs could be met by treated waste water Kajenthira, Arani, Laura Diaz Anadon, and Afreen Siddiqi.
