Executive overview
Why this report matters
Summary Insight: PUB operates as a statutory whole-of-cycle water authority integrating supply planning, demand management, reuse, drainage, and operational oversight. Transformation is being delivered through full-cost pricing signals, industrial recycling obligations, smart metering, appliance standards, efficiency co-investment, and customer engagement. This integrated architecture helps decouple water-demand growth from economic expansion while protecting long-term supply independence.
This Our Future Water Intelligence report provides an independent assessment of PUB’s demand-management architecture, tariff policy, industrial compliance model, digital capability, investment incentives, and supply-security strategy.
Water Efficiency Fund per-project grant cap, raised from SGD 1 million in July 2023 to co-invest public capital in mandatory industrial recycling infrastructure compliance.

Decision scope
Questions answered
How does Singapore fund industrial water-demand management?
Singapore uses targeted public co-investment to reduce the upfront cost of industrial recycling and efficiency infrastructure. Funding support complements regulatory obligations and helps convert compliance requirements into implementable projects.
What is driving the shift from voluntary to mandatory demand management?
Industrial demand growth cannot be contained through voluntary conservation alone. Mandatory recycling, formal efficiency planning, and compliance oversight provide clearer obligations for high-consumption users.
How does smart metering contribute to demand management?
Smart metering converts customer consumption into timely operational data. It supports leak alerts, consumption feedback, demand analysis, more accurate billing, and targeted engagement with households and businesses.
How does demand management support supply independence?
Demand management limits the volume of new water production required as the economy and population grow. This reduces pressure on climate-independent but energy-intensive supplies and preserves flexibility across the national portfolio.

Inside the report
Analytical coverage
Architectures: Tariff and Pricing Reform
Full-cost pricing and conservation charges communicate the scarcity and production cost of water while supporting infrastructure recovery and encouraging efficient consumption.
Enablement: Mandatory Industrial Compliance
Industrial demand management is moving from voluntary efficiency toward enforceable recycling obligations, formal water-efficiency plans, and targeted co-investment support.
Resolution: Smart Metering and Digital Monitoring
Smart meters, centralised network oversight, pressure management, consumption feedback, and leak alerts improve visibility across customer demand and utility operations.
Alignment: Appliance Efficiency Standards
Mandatory efficiency labels and minimum performance requirements reduce household and commercial demand by embedding water conservation into fixtures, fittings, and appliances.
Capability Building: Behavioural and Communication Infrastructure
Public campaigns, school education, customer feedback, waterway programmes, and professional knowledge exchange strengthen participation and institutional learning.
