How is Riyadh using technology to strengthen water security?
Riyadh is transforming its water infrastructure by transitioning from thermal desalination to Reverse Osmosis (RO), which significantly reduces energy consumption. To ensure operational efficiency, the city utilizes a centralized SCADA platform for real-time monitoring and control of the distribution network. This is paired with an Advanced Metering Infrastructure (AMI) rollout that uses smart meters to identify leaks instantly, cutting Non-Revenue Water (NRW) and providing a reliable, data-driven water supply in line with Saudi Vision 2030.
Riyadh’s pursuit of water security relies on technological innovation to modernize its infrastructure and secure sustainable supply sources. In an arid climate where desalination provides the vast majority of municipal needs, the city is prioritizing technologies that decouple water production from high energy consumption.

A pivotal advancement in the Kingdom's strategy is the accelerated transition toward Reverse Osmosis (RO) technology. Unlike older thermal methods that rely on heat to evaporate seawater, RO uses high-pressure pumps to push water through semi-permeable membranes. This shift has markedly improved operational efficiency, reducing the energy intensity of production and positioning Riyadh as a leader in cost-effective desalination.
Real-Time Oversight with SCADA Systems
The operational backbone of Riyadh’s water network is the Supervisory Control and Data Acquisition (SCADA) system. This digital platform acts as a central nervous system for the city’s water infrastructure, providing:
- Remote Monitoring: Operators can survey production plants, pumping stations, and reservoirs across the region from a single control center.
- Predictive Maintenance: By analyzing real-time data on pressure and flow, the system can identify anomalies that suggest equipment wear or potential pipe bursts before they occur.
- Automated Load Management: SCADA allows the utility to balance the water load across the grid, ensuring consistent pressure and reducing the stress on aging infrastructure.
Smart Metering and Non-Revenue Water (NRW)
Reducing Non-Revenue Water (NRW)—water that is produced but lost due to leaks or measurement errors—is a critical goal for the National Water Company (NWC). The rollout of advanced smart meters is the primary tool for this effort:
- High-Frequency Data: Unlike traditional meters, smart meters provide granular usage data, allowing for more accurate billing and consumption tracking.
- Automated Leak Alerts: These devices can detect constant flows that indicate an internal leak, sending automated notifications to customers and the utility.
- Network Transparency: By comparing the water pumped into a zone with the total measured by smart meters, the utility can pinpoint exactly where physical leaks are occurring in the distribution pipes.

Frequently Asked Questions: Water Technology in Riyadh
What is Reverse Osmosis (RO) and why is it better?
RO is a method of removing salt from water by pushing it through a very fine filter (a membrane) at high pressure. It is considered better than older thermal methods because it uses much less electricity to produce the same amount of clean water.
How does SCADA help manage the city's water?
SCADA is a software system that gathers data from sensors all over the city. It lets engineers see exactly how much water is in the tanks and how fast it’s flowing through the pipes, allowing them to fix problems remotely and instantly.
What is 'Non-Revenue Water'?
NRW is water that is lost through leaks, bursts, or theft before it can be billed to a customer. Reducing NRW is vital for sustainability because it ensures that the energy used to desalinate the water isn't wasted on water that just leaks into the ground.
