3 quarter inch pipe going out of water meter, Is that enough for 2 or more apartments

[Jay Smith]

I am wondering if I should keep the water meters in my name and get rid of one water meter and let each meter service 2 apartments? It costs 75 dollars a month even if you dont use any water! How far would one water meter go as far as usage? If I did that I would have to just split the bill between two tenants I guess? Anybody have knowledge on these things?
