Why Water Saving Matters in Singapore
Singapore’s amount of water available for daily life is limited. The country relies on desalination, imported water, and recycling, making water in the home a precious resource. The Public Utilities Board (PUB) encourages every person to practise water efficiency through its Water Efficiency Labelling Scheme (WELS) — a system that rates products from zero to three ticks based on how much water they use per minute.
By choosing PUB-approved devices, you’re not just cutting your water consumption and energy bill, but also helping the planet by reducing your carbon footprint.
Understanding PUB’s Water Efficiency Labelling Scheme (WELS)
WELS is a national water conservation program that helps homeowners identify water saving fixtures. The more ticks a product has, the better it is at saving water.
| WELS Rating | Meaning | Example Flow Rate |
|---|---|---|
| 0 Tick | Non-efficient | Above 9 L/min |
| 1 Tick | Basic efficiency | 7–9 L/min |
| 2 Ticks | Good efficiency | 5–7 L/min |
| 3 Ticks | Excellent efficiency | Below 5 L/min |
PUB maintains a list of approved saving devices — from taps to toilet cisterns, shower heads, and washing machines — all tested for water flow and durability.
The Top 5 PUB-Recommended Water-Saving Devices
1. Low-Flow Shower Heads
A low-flow shower head mixes air with water to maintain pressure while using less water overall. Many modern hand showers feature a flow rate of just 4–6 litres of water per minute, compared to traditional heads that use up to 12.
That means you can save up to 50% of your water each time you shower, while still enjoying consistent water pressure and a comfortable water temperature.
To save water, look for shower heads with a 3-tick WELS label. Installing a shower timer can also help you save by encouraging shorter baths and quicker rinses — a simple way to reduce water usage and energy consumption for every person in the home.
2. Dual-Flush Toilet Cisterns
Older toilets can use up to 9 litres per flush, while modern dual-flush toilet cisterns use only 3–4.5 litres. The half-flush button is ideal for the times you don’t need a full flush, helping to reduce the amount of water used per day.
Switching to a PUB-approved dual-flush toilet is one of the most effective water saving devices in the bathroom. You can save up to 15,000 litres of water per year, which also means paying less on your water bill.
If you’re wondering how to make the upgrade, consider consulting a professional plumber for professional installation — ensuring proper sealing, minimal leaks, and optimal water flow.
3. Tap Aerators and Mixer Taps
A tap aerator or mixer tap attaches to your kitchen tap or basin taps to control water flow and mix air into the stream. This simple technology allows the tap to deliver less water without reducing efficiency.
Aerators can cut water use by up to 40% and are easy to install. Whether you’re hand washing dishes or rinsing produce, the difference in comfort is barely noticeable — but your amount of water waste drops significantly.
Aerators are also one of the cheapest devices to help you save both water and energy, since heating cold water less often means reducing your energy bill too.
4. Water-Saving Washing Machines
Modern washing machines are among the most impactful water conservation devices in a household. PUB-approved products can save up to 30% of the amount of water per cycle compared to older models.
These machines optimise water flow, adjust water temperature, and reuse rinse cycles where possible. That translates to lower water bills, lower energy consumption, and a smaller carbon footprint.
If you’re shopping for washing machines in Singapore, always look for the WELS label. Reputable water companies and appliance brands provide detailed pdf guides on flow rate, capacity, and energy efficiency ratings.
5. Water-Saving Thimbles and Flow Regulators
Small yet mighty, flow regulators or thimbles are water saving devices that can be fitted inside taps or hand showers. They work by controlling the flow rate of water and air, reducing output without compromising comfort.
Depending on the product, they can save up to 35% of the amount of water used daily in your home. This upgrade is cost-effective and takes less than ten minutes to install — perfect to help you save instantly.
If you suspect leaks or reduced water pressure, it’s best to have a professional plumber inspect the fittings. Fixing even minor leaks can prevent hundreds of litres of water from being wasted every month.
How to Check If a Product Is PUB-Approved
To ensure your saving devices meet Singapore standards, always check for the WELS label. You can verify a product by visiting PUB’s official website and searching by brand or model.
If you prefer printed resources, PUB also provides pdf product listings that include flow rate, category, and water efficiency ratings. Look for three ticks — the highest rating for water efficient products in Singapore.
How Much Water and Money Can You Save?
Here’s a quick summary of potential savings from installing these devices:
| Device | Average Flow Rate | Water Saved | Potential Bill Savings |
|---|---|---|---|
| Shower Head | 4–6 L/min | Up to 50% | $5–$10/month |
| Tap Aerator | 4–5 L/min | 30–40% | $3–$6/month |
| Dual-Flush Toilet | 3–4.5 L/flush | 40–60% | $4–$8/month |
| Washing Machine | Variable | 25–30% | $6–$12/month |
| Flow Regulator | 5–7 L/min | 30–35% | $2–$5/month |
By combining these water conservation devices, you can significantly reduce both your water and energy consumption while promoting sustainable living.
Remember, more water saved doesn’t just lower utility bills — it protects the planet and ensures clean water for the world to share.
Simple Ways to Save Even More Water at Home
Beyond upgrading products, there are easy tips you can follow in your home to help you save even more:
- Fix leaks quickly — a dripping tap can waste 10,000 litres of water yearly.
- Turn off the water while brushing teeth or shaving.
- Use a shower timer to shorten showers to under five minutes.
- Choose washing machines and dishwashers with full loads only.
- Collect cold water while waiting for hot water to arrive — use it for plants.
- Replace old mixer taps or kitchen taps with PUB-rated water efficiency models.
- Install shower heads and hand showers with adjustable water flow.
Each small step reduces water waste and helps you live more sustainably in the long run.
Maintenance and Installation Tips
If you’re replacing devices or upgrading in the bathroom, always hire a professional plumber. Proper installation prevents leaks, ensures consistent water pressure, and guarantees compliance with PUB’s water efficiency standards.
For best results:
- Clean aerators every few months to remove mineral buildup.
- Check seals on toilet cisterns to avoid slow leaks.
- Inspect mixer taps and hoses for cracks.
- Use professional plumbing services for concealed shower or kitchen tap fittings.
The Bigger Picture: Water and Energy for a Sustainable Singapore
Every litre of water we save reduces the energy needed for treatment and transport. This helps cut down on emissions and reduces the overall carbon footprint across the globe.
By using water saving technology, Singaporeans are contributing to a cleaner, greener future — where every drop counts. PUB’s campaigns remind us that to save water is also to save energy, money, and our planet’s future.
Conclusion
Singapore’s drive toward sustainability starts with every household. From shower heads to washing machines, water saving devices are practical tools to help you save both water and energy daily.
Upgrading your products not only reduces water bills and energy bills, but also supports PUB’s mission of sustainable water use for generations to come.
