The City of Saskatoon is considering buying smart meters.

The meters track exactly how much water or electricity is being used by a home. The meters then instantly transmit those numbers to city officials.

Kevin Hudson, Saskatoon Light and Power's metering and sustainable electricity manager, said there's an environmental argument to be made  in favour of the move.

"Our customers would have better information that would help them save energy, or to lower their water consumption, and that would help them save money and help the environment," Hudson said.

Switching to the smart meters would cost Saskatoon more than $20 million. However, the city said millions of dollars will be saved through more accurate readings.
