Why the spat over differential water rates
within the City of Pittsburgh? It is a tempest that comes in city council on a pretty recurrent cycle
.... really, really
(read 2nd link there for a most thorough history of whole boring mess... you're welcome Tim). Someone may want to work out whether a few Homewood residents deserve a subsidy as well. Just saying is all....
But why? Well, the city's southern neighborhoods were effectively the last geographies added to the city of Pittsburgh... so generally they were annexed by the city after the era of water provision. Thus they probably had a pre-existing set of privatized pipes.
