Your water,
made clear.

Both are printed on your water bill or rates notice. The Property ID (sometimes shown as PID) identifies your connection, and the Meter number is printed on the meter itself and on your bill. Enter them on the Claim a meter screen to link your property.

You claim your meter the same way as everyone else – enter your Property ID and Meter number on the Claim a meter screen. WaterWatch then shows you your share of that meter’s usage and cost, not the whole connection. Your neighbours on the same shared meter each claim it too, using their own Property ID – everyone sharing has a different PID. The total is split between the properties sharing the meter; how it’s divided depends on your council’s arrangement, so your figures reflect the split that applies to your connection.

WaterWatch watches your meter for unusual, continuous flow – the kind that often signals a leaking toilet, dripping fitting or underground pipe. When the Home tab shows anything other than No leak detected, it's worth checking your taps and toilets, and contacting a plumber if you can't find an obvious cause. Catching it early keeps both water and your bill down.

The comparison gives your numbers context. On its own, "1,568 litres a day" is hard to judge – seeing it against the previous quarter and against similar households nearby tells you whether you're tracking high, low or about normal. It's a guide, not a target: a big garden, a pool or a larger household will naturally use more.

Flat-rate means you pay a fixed charge each quarter regardless of how much you use. Volumetric means you pay for the actual volume of water you use, usually per cubic metre (m³). The Billing tab shows both side by side for your connection so you can see how they compare for your usage. Your actual charging method is set by your water utility.

The line chart on Readings shows cumulative meter readings – so it always climbs; a steeper slope means heavier use over that stretch. Switch between 7 days, 30 days and 12 months to zoom in or out. The bar chart below shows how much you used in each month, quarter by quarter.

Yes. On the Readings tab, tap Export CSV to download your readings and billing data as a spreadsheet file you can open in Excel, Numbers or Google Sheets.

Open the Profile tab and tap Claim a meter, then enter the Property ID and Meter number for the other connection. You can link several meters to one account – handy if you own a rental or more than one property – and switch between them in the app.

Use the Moving option in your Profile to let your water utility know about a change of address. At your new place, claim that property's meter to start tracking it.

Costs shown in the app are estimates including GST, based on your meter readings and your connection's rate. They're there to help you plan – your actual bill from your water utility is the final word.
