Singapore Water Intelligence Report

This report evaluates how PUB is strengthening Singapore’s water security through the Four National Taps, NEWater, desalination, demand management, integrated wastewater infrastructure, and long-term climate adaptation.

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.

Target Audience

Utility Executives & System Operators: Evaluate how PUB integrates multiple water sources, treatment assets, distribution networks, wastewater systems, and digital operations within a single national utility model.
Regulators & Policymakers: Assess water pricing, conservation policy, industrial efficiency requirements, resource recovery, and long-term supply planning.
Infrastructure Investors & Financiers: Evaluate capital sequencing, delivery risks, energy requirements, asset resilience, and investment priorities across water, wastewater, drainage, and coastal infrastructure.

Report Deliverables

Water-Security Architecture: Examines the assets, networks, operating requirements, and supply balance of the Four National Taps.
Demand Management Assessment: Reviews tariffs, conservation incentives, industrial demand, internal recycling, and long-term consumption pressures.
Circular Infrastructure Assessment: Evaluates NEWater, Deep Tunnel Sewerage System (DTSS) Phase 2, Tuas Nexus, and integrated resource recovery.
Climate Risk Assessment: Reviews drought, intense rainfall, coastal exposure, drainage requirements, and the proposed Long Island project.
Operational Assessment: Assesses network losses, smart metering, automated plant control, treatment energy, asset monitoring, and system reliability.

The Five Strategic Pillars

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.
Enablement: Industrial demand and water pricing

Evaluates how PUB uses tariffs, conservation measures, efficiency requirements, and internal recycling to manage changing municipal and industrial demand.
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.
Alignment: Treatment efficiency and utility decarbonization

Reviews how PUB is reducing the energy and emissions requirements of water treatment through advanced membranes, process improvement, renewable electricity, and integrated infrastructure.
Capability Building: Coastal defence and climate adaptation

Explains how PUB is planning for drought, intense rainfall, sea-level rise, low-lying asset exposure, and the proposed Long Island coastal-protection project.

Operational Excellence & Resilience

PUB’s integrated operating model connects water supply, drainage, sewerage, wastewater treatment, reclamation, and coastal protection. Smart meters, real-time telemetry, automated plant control, and coordinated asset planning give operators detailed visibility across the complete urban water cycle.

DTSS Phase 2 and Tuas Nexus strengthen wastewater conveyance, treatment, reclamation, and resource recovery, while NEWater and desalination provide weather-independent supply. The report evaluates how these assets support reliable service, industrial water security, operational efficiency, and long-term resilience.

Expert Analysis: FAQs

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.
