Who is responsible for such city infrastructure in US?

In Russia it is mostly local state who owns reservoirs, pumping and filtering stations, pipes and all that stuff. That enterprises earn money from clients - citizens and businesses, but, if necessary state budget will provide finacial and administrative support. Of course there are some stealing and corruption, but I didn't recall any case when all money was stolen to the level of total infrastructure fall. Even most greedy and criminal mayors and governors are sane enough to not destroy basic infrastructures.
