Don't pay a penny more than you have to

We use your meter readings to help calculate your water bill so you only pay for the water used. We recommend submitting meter readings every month.

Step 1

Find your water meter using interactive map on your online customer portal here.

Step 2

If your meter is safe to access, note your reading (we only need the black digits).

Step 3

Log in to the customer portal and submit the meter reading you took.

Keep an eye on your usage

Your meter reading data is tracked in the consumption dashboard in the portal, so you can keep an eye on things.
