Does the state forbid competition with so-called natural monopolies?
<p>(I don't need information about specific country, so it's OK to post information about laws of country that you know, just remember to include the name of the country in your post).
For example, I heard that the state forbids competition with public utilities. So you can't have two water pipes systems in your house, even if you're willing to pay big money for it. You can't open new water-pipes company, it would be against the law.
Is it correct? I just can't find anything that would either support or disprove such information.
If it's correct, then I would want you to provide me few examples of this.</p>

<p>In the US it depends on state law.</p>

<p>According to <a href="http://docs.legis.wisconsin.gov/document/statutes/196.50" rel="nofollow noreferrer">Wisconsin law</a>:</p>

<blockquote>
  <p>(a) Except as provided in par. (am), the commission may not grant any person a license, permit or franchise to own, operate, manage or control any plant or equipment for the production, transmission, delivery or furnishing of heat, light, water or power in the municipality, if there is in operation under an indeterminate permit a public utility engaged in similar service in the municipality, unless the person seeking the license, permit or franchise secures from the commission a declaration, after a public hearing of any interested party, that public convenience and necessity require the delivery of service by the applicant. </p>
</blockquote>

<p>So it's not technically <em>prohibited</em> to have a second utility under Wisconsin law; it's just that you have to show a very good reason.</p>
