Saudi Arabia, the world’s largest desert kingdom, faces a unique and urgent water challenge. With limited natural freshwater resources, a fast-growing population, and rapid industrialization, the effective treatment and reuse of wastewater is not just an environmental necessity-it’s a strategic imperative. As the nation pursues Vision 2030 and aims for sustainable development, advanced sewage treatment solutions are critical for protecting public health, conserving water, and supporting economic growth. This blog explores the sewage treatment landscape in Saudi Arabia, the pressing issues, and why the SUSBIO ECOTREAT IoT-enabled packaged STP is the most advanced, future-ready solution for the Kingdom.
The Sewage Treatment Scenario in Saudi Arabia
Water Scarcity and Urbanization
Saudi Arabia is one of the driest countries in the world, with minimal rainfall and scarce renewable water sources. The country relies heavily on desalinated water and non-renewable groundwater, both of which are costly and vulnerable to overuse. As cities expand and industries grow, the demand for water rises, putting further pressure on these limited resources.
Current Wastewater Infrastructure
- Centralized and Decentralized Systems: Saudi Arabia operates a mix of centralized and decentralized wastewater treatment plants (WWTPs), serving urban centers and isolated communities alike.
- Connectivity Gaps: Despite progress, about 40% of Saudi households are not directly connected to centralized WWTPs. In many cities, sewage is collected by tanker trucks and transported to plants, causing congestion and leaving significant volumes untreated.
- Treatment Capacity: As of 2021, there were 33 WWTPs with a capacity of 748 million cubic meters per year, with more under construction. Yet, the system struggles to keep pace with urban growth and regulatory targets.
Reuse and Reclamation Efforts
- Agricultural and Industrial Reuse: Treated wastewater is increasingly reused for irrigation, landscaping, and industrial applications, especially in major cities like Riyadh, Jeddah, and Dammam.
Aquifer Recharge: Managed aquifer recharge using treated wastewater is being adopted to combat groundwater depletion in rural valleys, offering a cost-effective alternative to desalinated water.
Key Issues in Saudi Sewage Treatment
- Untreated Wastewater and Environmental Risks
- A significant portion of sewage remains untreated due to infrastructure gaps, leading to contamination of water resources and damage to aquatic ecosystems.
- Untreated effluent poses public health risks and undermines environmental sustainability goals.
- High Costs and Energy Demands
- Desalination and conventional treatment are energy-intensive and expensive, with desalinated water costing up to $5/m³ compared to $0.25–0.50/m³ for aquifer recharge with treated wastewater.
- Traditional STPs require substantial land, skilled labor, and ongoing maintenance, making them less viable for many communities.
- Regulatory and Sustainability Pressures
- Saudi Arabia’s government aims to treat all wastewater by 2025 and increase daily treatment capacity to 6.8 million cubic meters by 2035.
- Stricter regulations demand advanced tertiary treatment, especially for water reuse in agriculture and industry.
The Importance of Advanced Sewage Treatment for Saudi Arabia
Water Conservation and Reuse
- Treated wastewater is a vital resource for irrigation, landscaping, and industrial use, reducing dependence on expensive desalinated water and overdrawn aquifers.
- Reuse supports food security, urban greening, and sustainable industrial growth.
Environmental and Public Health Protection
- Advanced treatment prevents pollution of scarce water sources, protects biodiversity, and reduces the risk of waterborne diseases.
Economic and Social Benefits
- Efficient wastewater management lowers operational costs, supports compliance with regulations, and fosters economic development.
- Recycled water reduces utility bills for municipalities and industries, while supporting job creation in the environmental sector.
