Bahrain Climate Resilience REPORT

Climate Resilient Water Resources Management in Bahrain

How Bahrain is securing a fully desalination-based water system while tackling deep subsidies, energy intensity, and climate-driven flood and heat risks.

Summary Insight: Bahrain has achieved a high degree of water security by shifting entirely to non-conventional water sources, with desalinated water providing 100% of the public supply since 2020 and reducing water stress from 195% of renewable resources in 2000 to 156% in 2021. At the same time, near-total dependence on gas-powered desalination, an emission factor of 13.13 kg of carbon dioxide per cubic metre, and a tariff structure where users pay only about 20% of full cost expose the system to financial and climate risks that demand integrated water–energy–finance reforms.

Target Audience

Utility & Ministry Leaders: Managing fully desalination-based public supply under fiscal and climate stress.
Policy & Regulators: Designing tariff, subsidy, and wastewater pricing reforms that support resilience and equity.
Investors & IFIs: Assessing long-term subsidy exposure, renewable integration, and smart metering opportunities in Bahrain.

Report Deliverables

System-wide assessment of desalination, storage redundancy, and drainage–flood risk linkages.
Roadmap for tariff and wastewater pricing reform to strengthen cost recovery and conservation incentives.
Options for scaling smart metering, renewables integration, and rainwater/greywater reuse guidelines.

The Five Strategic Pillars

Architectures: Operating a fully desalination-based public water system, backed by 679 million imperial gallons of storage—equivalent to more than four days of average national demand in 2022.

Enablement: Expanding the national Smart Water Meter Programme beyond 43% completion (June 2019) to cut losses, improve demand management, and sharpen visibility of consumer behaviour.

Resolution: Reducing system vulnerability to power disruption and extreme heat by integrating solar photovoltaics into desalination and pumping, and transitioning wastewater plants toward resource recovery hubs.

Alignment: Synchronising tariff reform, wastewater pricing, and renewable integration with long-term climate and energy strategies to cut emissions per cubic metre and stabilise public finances.

Capability Building: Equipping the Water Resources Management Unit and utilities to issue and enforce rainwater harvesting and greywater recycling guidelines, normalising decentralised resilience at building scale.

Operational Excellence & Resilience

Bahrain’s urban water system operates under compound climate and energy pressure, with 100% of public supply produced via electricity-intensive desalination in a tropical, dry climate exposed to extreme heat, sea-level rise, and intense rainfall. By improving storage redundancy, scaling smart metering, and integrating renewable energy, the Kingdom can mitigate projected freshwater reserve losses of 50–100 million cubic metres per year and reduce the strain on public finances created by deep water subsidies.

Subsidy Burden & Emissions ≈20% Cost Recovery

On average, customers cover only about one-fifth of full municipal water supply costs, while desalination emits roughly 13.13 kg of carbon dioxide per cubic metre, underscoring the need for tariff reform and renewable integration.

Expert Briefing: FAQs

How is Bahrain’s climate-resilient water management financed?
Bahrain’s system is largely funded through state budgets and deep operating subsidies, with current tariffs recovering only about 20% of costs; reforms around domestic and wastewater tariffs are critical to unlock future investment capacity.

What role do renewables play in Bahrain’s water–energy nexus?
Integrating solar photovoltaic systems into desalination and pumping can lower fossil fuel reliance, reduce the weighted emission rate of 13.13 kg/m³ of carbon dioxide, and strengthen resilience ahead of potential liquefied natural gas imports after 2030.

How are decentralised measures improving resilience?
National guidelines for rainwater harvesting and greywater recycling, combined with smart metering and improved drainage, diversify local supplies, reduce flood risk during intense storms, and limit demand growth on the desalination network.
