Executive overview
Why this report matters
Summary Insight: Bahrain faces interconnected pressures arising from desalination dependence, dense urban development, sealed coastal surfaces, intense rainfall, sea-level rise, storm surges, groundwater degradation, and growing infrastructure demand. The report examines how conventional drainage and wastewater systems can be complemented by bioswales, detention basins, permeable pavements, wetlands, rain gardens, infiltration zones, green roofs, and green corridors supported by integrated planning, water-sector reform, and climate-aligned finance.
This Our Future Water Intelligence report provides an independent assessment of Bahrain’s urban and coastal flood exposure, stormwater and wastewater architecture, Blue-Green Infrastructure options, water governance, investment priorities, financing mechanisms, and institutional capability requirements.
Projected cumulative desalination expansion is expected to cost about USD 11 billion, consume 15.9 billion m³ of natural gas, and emit 78 million tonnes of carbon dioxide, while current tariffs recover only around 20% of supply costs and municipal water subsidies reached BHD 123 million. These pressures reinforce the case for tariff reform, wastewater charging, climate finance, and investment in Blue-Green Infrastructure.

Buyer relevance
Who the report is for
- City & National Planners: Assess how masterplans, building codes, zoning, streetscapes, public spaces, and development standards can embed Blue-Green Infrastructure across urban districts.
- Water Utilities & Regulators: Examine how drainage, wastewater reuse, desalination, groundwater protection, and demand management can be coordinated through integrated water-resources planning.
- Infrastructure Investors & Climate Financiers: Evaluate stormwater fees, retention incentives, Green and Blue Bonds, public-private partnerships, and blended-finance structures for resilience projects.

Decision scope
Questions answered
What does the Bahrain flood and stormwater infrastructure report assess?
The report evaluates urban and coastal flood risk, conventional drainage, wastewater systems, Blue-Green Infrastructure, groundwater protection, climate adaptation, water governance, infrastructure investment, sustainable finance, and institutional capability as connected parts of Bahrain’s resilience strategy.
How is Bahrain’s flood and stormwater transition funded?
Bahrain’s transition can be supported through public infrastructure investment, water and wastewater tariff reform, public-private partnerships, stormwater charges, climate funds, and sustainable finance instruments. Green and Blue Bonds and blended finance can support eligible adaptation, water-management, biodiversity, and resilience projects.
What defines Bahrain’s Blue-Green Infrastructure approach?
The approach integrates bioswales, detention and retention basins, permeable pavements, wetlands, rain gardens, green roofs, infiltration systems, and rainwater harvesting into existing and new urban development. These measures complement conventional drainage while restoring elements of the urban water cycle.
How do hybrid systems improve resilience compared with grey-only drainage?
Hybrid systems slow, retain, infiltrate, reuse, and filter runoff before it enters conventional networks. This can reduce peak discharges, protect groundwater and coastal waters, lower wastewater loads, defer some drainage upgrades, and provide additional cooling, biodiversity, and public-space benefits.
Who is the report designed for?
The report supports national and municipal planners, drainage operators, water utilities, regulators, environmental agencies, infrastructure investors, climate funds, engineering firms, and organisations evaluating flood-resilience and Blue-Green Infrastructure opportunities in island and coastal cities.

Inside the report
Analytical coverage
Architectures: Integrated stormwater, wastewater, and urban systems
Examines Bahrain’s infrastructure as a connected system of distribution networks, wastewater treatment, drainage openings, pumps, collection tanks, trunk infrastructure, coastal assets, and distributed Blue-Green Infrastructure.
Enablement: Climate-risk mapping and urban planning
Evaluates how rainfall monitoring, coastal-risk assessment, land-use planning, groundwater information, drainage modelling, and development controls can guide investment across densely urbanised and low-lying areas.
Resolution: Blue-Green stormwater management
Assesses bioswales, detention and retention basins, permeable pavements, rain gardens, green roofs, wetlands, infiltration zones, and rainwater-harvesting systems. These measures can slow, store, filter, reuse, and infiltrate runoff before it overwhelms conventional networks.
Alignment: Water security and climate-resilient development
Analyses the alignment of stormwater investment with national water strategy, climate-resilience programmes, water-sector legislation, product standards, integrated water-resources management, wastewater reuse, and regional coordination.
Capability Building: Institutional and operational readiness
Maps the planning, licensing, monitoring, procurement, emergency-response, asset-management, and maintenance capabilities required across water, environmental, municipal, and public-works institutions.
