Executive overview
Why this report matters
Summary Insight: PUB manages Singapore’s complete urban water cycle through unified planning, asset ownership, regulation, and operations. The Four National Taps diversify supply across local catchments, imported water, NEWater, and desalination, while tariffs, digital systems, wastewater reclamation, and climate-resilience investment support long-term municipal and industrial water security.
This Our Future Water Intelligence report provides an independent assessment of PUB’s supply strategy, utility performance, demand-management policies, infrastructure risks, and long-term capital priorities ahead of the 2061 water-agreement horizon.
This target represents the share of demand Singapore intends to meet through weather-resilient water supplies.

Buyer relevance
Who the report is for
- Utility Executives & System Operators: Assess how national water resources, bulk supply, utilities, irrigation, wastewater, reuse, energy dependencies, service performance and operational monitoring interact across Singapore's water system.
- Regulators & Policymakers: Examine how national strategy, sector regulation, basin governance, environmental standards, tariff policy, institutional mandates and public accountability shape implementation.
- Infrastructure Investors & Financiers: Evaluate capital allocation, asset condition, project pipelines, climate exposure, delivery risk, operating capability and long-term infrastructure value across the national water portfolio.

Decision scope
Questions answered
What are Singapore’s Four National Taps?
The Four National Taps are local catchment water, imported water, NEWater, and desalinated water. The report evaluates how PUB manages these sources as an integrated portfolio to strengthen supply reliability and reduce exposure to any single source.
Why does the 2061 water-agreement horizon affect infrastructure planning?
The 2061 horizon creates a clear planning point for expanding domestic supply resilience. The report assesses how NEWater, desalination, demand management, storage, and infrastructure investment support Singapore’s long-term water-security strategy.
Why is industrial demand important to PUB’s strategy?
Industrial growth is increasing demand for reliable, high-quality water. The report evaluates how pricing, efficiency requirements, internal recycling, NEWater, and dedicated supply planning can manage industrial demand without weakening municipal resilience.
How is PUB responding to long-term climate risk?
PUB integrates drought management, drainage, flood protection, coastal defence, and water-supply planning. The report examines how these responsibilities shape infrastructure investment, operational coordination, and the proposed Long Island project.

Inside the report
Analytical coverage
Architectures: Four National Taps and supply diversification
Examines how PUB coordinates local catchments, imported water, NEWater, and desalination to manage supply risk and reduce dependence on any single source. The analysis connects source diversity, asset interdependence, service continuity, environmental performance and long-term resilience.
Enablement: Industrial demand and water pricing
Analyzes how PUB uses tariffs, conservation measures, efficiency requirements, and internal recycling to manage changing municipal and industrial demand. These capabilities determine whether operators can coordinate demand, asset performance, customer service and incident response.
Resolution: NEWater, DTSS Phase 2, and Tuas Nexus
Assesses how PUB integrates wastewater conveyance, treatment, NEWater production, energy recovery, and waste management through DTSS Phase 2 and Tuas Nexus. The assessment identifies where targeted controls, rehabilitation, preparedness and accountable evidence can close the most material gaps.
Alignment: Treatment efficiency and utility decarbonization
Evaluates how PUB is reducing the energy and emissions requirements of water treatment through advanced membranes, process improvement, renewable electricity, and integrated infrastructure. Effective alignment depends on clear mandates, investable priorities, coordinated delivery and transparent performance oversight.
Capability Building: Coastal defence and climate adaptation
Reviews how PUB is planning for drought, intense rainfall, sea-level rise, low-lying asset exposure, and the proposed Long Island coastal-protection project. Sustained capability depends on workforce skills, interoperable data, institutional learning and disciplined implementation.
