Probably only makes sense if you have consistent pressure.
Why are you so invested in someone else water waste?

Can you explain this? My electric company just change the meter for a smart meter. Can I use rtl-sdr dongle to pick up the signal?
It depends on the protocol. Many of the newest are encrypted (so inaccessible in the utility has a program and a Home Area Network. Is it Xcel Energy by chance?
Most probably, yes. There's list of water meters which can work with rtl-sdr. 'rtlamr' software is designed to decrypt such signal and the list is on their github page.
Sorry, i sounded like it's very easy to achieve. But no, it does require little more extra work. You'll need 'home assistant' or some sort of smart home software kind of like google home. Then you'll need proper software to decode the signal you receive from your dongle, such as rtl-433 and rtl-tcp. These softwares will decode the signal and send it to 'mqtt' broker. You can then subscribe to a particular activity (aka topic) within mqtt broker and this subscription will alert you. I know, i sound like blabbering but actually easy to achieve. Please read more about all the 'softwates' i mentioned and see if this is something you can achieve. I did it once about 2 years ago, and still going strong.
I haven't used mine in a couple of years due to the batteries. I was wondering if the USB rechargeable AAs would work as a decent replacement, since they should output a constant 1.5v until 80-90% charge used.
The thing is with rechargeable lithiums, the cells stay at 1.5v until depleted. So the device will just die, giving no low battery warning.
Typical NiMH rechargeables are 1.2v, so they will give low battery warnings from the start.
I tried alkaline Duracells once (didn't want to go too cheap experimenting with the not-recommended normal AA batteries), and they worked fine for about a month, then started acting all wonky. Got constant low battery warnings, and a few dead warnings, yet the device would come back to life a few minutes later. They did last like 8 months before completely going out though lol
