Split water bill in Pittsburgh area?

[Michael D.]

I was thinking about splitting out the water meters on my 9-unit in the Pittsburgh area (PWSA) and called the water company about it. They explianed what I would need to do, but also suggested a much less expensive alternative: sub-metering.

I would install my own meters on each line, and simply divide up my water bill accordingly.

Since the idea came from the water company, I have to assume that this is legal, but how can I find out with certainty? My manager isn't sure about it.

Thanks!
