Executive overview
Why this report matters
Summary Insight: PUB coordinates water supply, water catchments, drainage, wastewater collection, reclamation, and flood management under an integrated national mandate. This report examines how diversified sources, NEWater, desalination, deep-tunnel conveyance, demand management, digital monitoring, coastal protection, and resource recovery support long-term water security.
This Our Future Water Intelligence report provides an independent assessment of PUB’s governance model, capital strategy, supply resilience, water-reuse system, drainage responsibilities, digital capability, energy exposure, and long-term infrastructure planning.
The total capital program budget allocated for the deep-tunnel sewerage system, forming the primary infrastructure foundation for Singapore's closed-loop water recycling strategy over a multi-decade horizon.

Buyer relevance
Who the report is for
- Utility Executives & System Operators: Assess how PUB coordinates catchments, imported supply, reservoirs, treatment, distribution, wastewater conveyance, reclamation, desalination, drainage, and flood operations.
- Regulators & Policymakers: Examine how statutory integration, tariff policy, water-efficiency requirements, industrial demand management, environmental regulation, and land-use planning influence water security.
- Infrastructure Investors & Financiers: Evaluate public financing, tariff-supported revenue, project-delivery structures, energy exposure, asset resilience, and long-term infrastructure recovery.

Decision scope
Questions answered
How does PUB finance long-term water infrastructure?
Major investments are supported through public-sector capital planning, operating revenue, water charges, and approved financing arrangements. Funding decisions must balance national water security, project delivery, operating costs, affordability, and the long asset lives of treatment and conveyance infrastructure.
Why is the deep-tunnel sewerage system strategically important?
The system conveys used water through deep gravity tunnels to centralised reclamation facilities. This supports land efficiency, reduces reliance on distributed pumping, enables large-scale treatment, and strengthens the infrastructure foundation for water reuse.
How does digital technology improve PUB’s operations?
Smart meters, network sensors, process controls, weather monitoring, asset information, and operational analytics provide a clearer view of demand, leakage, treatment performance, drainage conditions, and equipment health. This visibility supports earlier intervention and predictive management.
How does PUB address the energy intensity of water security?
The agency combines process efficiency, energy recovery, solar deployment, research, advanced treatment, and operational optimisation to manage the energy requirements of water reuse and desalination. These measures help reduce exposure while preserving supply resilience.

Inside the report
Analytical coverage
Architectures: Integrated governance across the urban water cycle
Examines how PUB coordinates water resources, supply, distribution, wastewater collection, reclamation, drainage, and flood management within a unified institutional framework. This structure connects source planning, environmental management, customer policy, and infrastructure investment.
Enablement: NEWater and closed-loop resource management
Evaluates how advanced wastewater treatment and water reclamation convert used water into a strategic supply resource. The analysis considers industrial use, indirect potable applications, quality assurance, public confidence, conveyance, and integration with the wider supply system.
Resolution: Desalination and climate-resilient supply diversification
Assesses how desalination complements catchment water, imported supplies, and NEWater by providing a rainfall-independent source. The report evaluates energy exposure, treatment efficiency, plant integration, operational flexibility, and long-term supply resilience.
Alignment: Drainage, flood resilience, and coastal adaptation
Analyses how canals, drains, reservoirs, pumping assets, source controls, catchment planning, flood forecasting, and coastal protection work together. Infrastructure decisions must account for intense rainfall, urban density, sea-level exposure, and competing land uses.
Capability Building: Digital operations and demand management
Maps how smart meters, network telemetry, process controls, customer information, water-efficiency programmes, operational analytics, research, and workforce development strengthen institutional capability. These systems support earlier intervention and more efficient use of water and energy.
