3. Byrne Looby Experience
Delivering municipal and industrial water and wastewater infrastructure projects across the Middle East
Industrial Developments
Jubail - Hydraulic Model for Water Reuse
Waad al Shamal – Water and Wastewater concept design

4. 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

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Over 80% of water is withdrawn from non-renewable groundwater aquifers, estimated to contain only a year supply of water

6. 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

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

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

10. 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

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

12. Efficient Waste Solutions

13. Water Reuse Systems

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

15. Economic and Environmental Factors

16. 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

17. Economic and Environmental Observations
Thermal desalination, using fossil fuels, without cogeneration is never as economically competitive as Reverse Osmosis

18. Economic and Environmental Observations
It is estimated that 29% of total industrial water withdrawls could be saved through water reuse, recycling and conservation methods

19. Economic and Environmental Observations
It is estimated that 26% of urban water needs could be met by treated waste water
