I received mail from a company that was selling insurance to cover gas and water/sewage lines that extend from the home to the public utilities' lines. I've been a homeowner for 15 years and this is the first I've heard of it. I thought it was a scam so I called the Better Business Bureau. The only information I acquired was that the business was legit. I reached out further and call the city water and found out that the service is indeed legit and they gave me the name and number of a company that they refer customers to. Though others may already know about it, I thought I might share what I found out. It is surely worth the investment when you think about a pipe bursting between your property and the city's.
