Water Efficiency Fund
PUB co-funds businesses to audit, pilot and implement water-saving measures, from a 70%-funded water audit up to S$5 million for a full-scale water recycling plant. Aimed at heavier water users (from 1,000 cubic metres a month), it pays you either per cubic metre of water saved or a share of capital cost, whichever is lower.
S$30,000 (assessment), S$150,000 (pilot study), S$300,000 (water-efficient equipment), S$5 million (recycling / IWSDF projects)
Who qualifies
- ✓Premises using at least 1,000 m3 of water a month (smaller sites can apply collectively)
- ✓Manufacturers, hotels, F&B centrals and other water-intensive operations
- ✓Companies exploring water recycling or alternate water sources
- ✓Early adopters of innovative water tech (IWSDF track, 10,000 m3/month sites)
What it pays for
- Water efficiency assessment / audit costs (meters, instrumentation, lab tests)
- Small-scale pilot recycling plants to prove feasibility
- Full-scale recycling plants and alternate water sources
- Water-efficient equipment and process changes

Advisor's note
Payouts hinge on verified water savings - if you achieve less than 75% of what you declared, the back half of the grant is at risk, so declare conservatively. Rainwater harvesting and basic tap/cistern swaps are explicitly not fundable. Application pack verified (updated 2 Oct 2025; PUB press release Mar 2026 confirms fund active).

3R Fund · National Environment Agency (NEA)
3R Fund (Reduce, Reuse, Recycle)
NEA co-funds up to 80% of projects that reduce or recycle waste, capped at S$1 million, with the payout pegged to how many tonnes of waste you actually divert. Open to companies and organisations of any type, but the project must cut at least 100 tonnes of waste over its duration.
EEG · Enterprise Singapore / NEA
Energy Efficiency Grant
Co-funds up to 70% of pre-approved energy-efficient equipment (LED, aircon, refrigeration, cooking equipment and more) for SMEs in supported sectors like F&B, manufacturing, and retail.
REG(E) · Singapore Economic Development Board (EDB)
Resource Efficiency Grant for Emissions (REG(E))
EDB co-funds up to 50% of projects in manufacturing facilities and data centres that measurably cut carbon, such as energy-efficiency retrofits, non-CO2 greenhouse gas reduction or flare gas recovery. The scheme is open until end-FY2030 and the grant is sized by the carbon abatement your project actually delivers.
