Water and Wastewater in the Development of Industrial Cities
Sam Murdock, Director of Water Services, Byrne Looby Partners

Byrne Looby ExperienceInternational civil engineering consultants
Byrne Looby ExperienceDelivering 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
Mesaieed Industrial City – TSE system for Qatar Petroleum
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

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Over 80% of water is withdrawn from non-renewable groundwater aquifers,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

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 CitiesOptions:- Piped desalinated water- Groundwater source- Supply by tankers
Challenges:- Cost- Lack of infrastructure- Security of supply - essential
Water Supply for Industrial CitiesDesalination 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 CitiesChallenges:- 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 reuseClose collaboration with operator to identify process change possibilities
Economic and Environmental Factors

Typically for inland cities, the provision of desalinated water is more energy-intensive than the secondary or tertiary treatment of local wastewater

Thermal desalination, using fossil fuels, without cogeneration is never as economically competitive as Reverse Osmosis

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

It is estimated that 26% of urban water needs could be met by treated waste water
