Types of Water Meters in Singapore
🌀 Analogue Water Meters
These are the most common meters in older HDB flats and some landed properties. They have rotating dials or a digital counter with black and red numbers.
📲 Digital / Smart Water Meters
Used in newer housing estates and condominiums, these meters display water usage on an LCD screen. PUB, as Singapore’s national water agency, is progressively rolling out the smart water meter system under its Smart Water Meter Programme as part of broader water conservation efforts.
How to Locate Your PUB Water Meter
Your meter’s location depends on your property type and address:
HDB flats: Inside a vertical riser along the corridor or outside the flat unit
Condos: Usually hidden in service ducts or meter cupboards along the hallway
Landed homes: Near the boundary wall or front gate, sometimes inside a box marked “Water Meter”
Tip: Look for a blue PUB logo and a meter box cover if you’re unsure. The deployment of smart meters has been ongoing across various locations, including Bukit Batok, Tampines North, and Jurong West, with each phase targeting different premises in the network.
Step-by-Step: How to Read Your PUB Water Meter
🔘 For Analogue Water Meters:
- Open the meter box or access panel.
- Find the black and white digits – these are in cubic metres (m³), which PUB uses for billing.
- Ignore the red digits – they are in litres and for internal tracking.
- Read from left to right. For example: 000315 = 315 m³ used.
📸 Tip: Take a photo each time you check to track changes easily and maintain accurate meter readings.
📟 For Digital / Smart Meters:
- Wake the screen (some models require a button press).
- Look for the main reading in cubic metres.
- Some smart meters show real-time usage, flow rate or alerts for abnormal consumption.
- Record the number displayed for your own log.
For customers with access to MySmartWaterMeter portal, users can see their consumption data online, making this process even more convenient for both households and business premises.
How to Calculate Your Water Usage
To estimate how much water your household is using, this is the way to track consumption:
Formula: Current reading – Previous reading = Water consumption (in m³)
🧾 Example: Previous: 315 m³ Current: 325 m³ Usage = 10 m³
This means you’ve used 10,000 litres of water during this period (since 1 m³ = 1,000 litres).
Troubleshooting High Water Bills
If your PUB water bill is unusually high, here are a few things to check with confidence:
✅ Test for Leaks:
- Turn off all taps and appliances in the house.
- Check the water meter—if the digits are moving, you may have a hidden leak.
- Common leak sources:
- Toilet flush system
- Water heater valves
- Outdoor taps
📞 Call a plumber for professional leak detection if needed, or contact a PUB officer if you notice irregularities that might indicate issues with the water supply network.
PUB’s Smart Water Meter Rollout (What You Should Know)
