Dubai

City Water System

Dubai’s water system operates under arid conditions with negligible renewable freshwater and sustained urban, commercial and visitor demand. Desalination supplies the potable system, while digital distribution, wastewater reuse and large sewerage and drainage programmes shape the wider urban water cycle. Dubai Electricity and Water Authority leads water production and distribution, while municipal and regulatory institutions share responsibility for wastewater, drainage, development and environmental performance. Long-term resilience depends on coordinating these institutions with private infrastructure delivery.

Supply & Distribution

Demand for desalinated water reached 161.505 billion imperial gallons in 2025, with peak daily demand of 487 million imperial gallons. Reported production capacity was 531 MIGD, targeted to rise to 735 MIGD by 2030. Dubai is shifting new supply toward power-independent seawater reverse osmosis, including the Hassyan independent-water-producer model. Smart metering, supervisory control, leak detection and predictive maintenance support network performance; reported water loss of 4.4% indicates the operational value of that digital capability.

Wastewater, Reuse & Drainage

Treated wastewater is positioned as a substitute for desalinated water in suitable municipal, landscaping, industrial and district-cooling applications. The stated municipal ambition is to recycle all wastewater, but achievement depends on treatment, conveyance and dependable end-use demand. Sewerage and stormwater are receiving separate large-scale investment: the Strategic Sewerage Tunnels programme addresses long-term collection and treatment needs, while Tasreef is designed to strengthen drainage capacity after severe rainfall exposed urban flood vulnerability.

Investment & Resilience

Dubai’s delivery model combines public utility investment with long-term private concessions and offtake arrangements. The AED 80 billion Strategic Sewerage Tunnels and AED 30 billion Tasreef values represent distinct programmes and are not treated as annual expenditure. Water security investment also includes the Hassyan desalination project and aquifer storage and recovery designed to provide an emergency reserve. The key test is whether capital scale is matched by institutional coordination, operating capability, lower-carbon production and resilience to extreme heat and intense rainfall.

Key Challenges

1. Meeting rapid residential, visitor and industrial demand growth in a water-scarce environment.
2. Reducing the energy and emissions exposure of desalination while expanding capacity.
3. Scaling wastewater reuse through treatment, distribution and durable end-use demand.
4. Delivering sewerage and stormwater megaprojects with clear risk allocation and coordinated oversight.
