Why I think "the Pipeline" thing is a BAD idea:

[MineralMan]

1. All plumbing requires maintenance.

They just relined all the sewer main lines in St. Paul, MN. Or, at least, they're doing it as an extended project. They did my street this year. The old main sewer lines in my 1950s subdivision was having problems. So, they relined the pipes with plastic liners that were installed and cured in place without digging up the street.

I don't know where you live, but there are pipelines everywhere. They supply you with water and sewage handling. They bring natural gas to your home and to businesses. There are pipelines throughout most cities. Yes, they require maintenance, but they give excellent service for many years. You don't see them. You don't even know most of them exist.

Properly installed and maintain pipelines cause very, very few problems, especially given the hundreds of miles of them under every city. We know how to build pipelines. We know how to maintain them. We just have to use that knowledge to create and maintain good pipelines.

Ever seen a train accident? Trains full of tank cars are the alternative to pipelines. You may remember the oil tanker train that exploded in the heart of a Canadian town. Trains need far more maintenance than pipelines, and are dangerous, as well.
