These are natural monopolies, and require government regulation (but not ownership). These are industries where competition on a local scale just isn't practical. Imagine if there was more than one sewer system that you could pay for, or three different roads side by side that you could take to work. In these cases, the government has to make sure that the owners of these companies cannot just charge whatever they feel like, or else they would charge the people more than what they would really be willing to pay. Railroads are the classic example, but there are many others.
