> I hope in america public utilities are not only controlled by the government. Because where I am from public utilities can be publicly or privately controlled. As long as they are all playing by the same rules many private companies have made lots of money providing public utilities.

Water/Sewage and Trash are typically run by the city/county government, although it is common for the actual work to be handled by a contracted company.

Power, natural gas, phone, and most others is almost always a private company.
