So then naturally your going to get a higher dose closer to the water treatment plant and a lesser dose further from the plant, as chlorine parishes rather quickly.

Oh?

What kind of chlorinated compound is building up in the piping from the water company to my house?

Chlorine doesn’t buildup in pipes any more than mash wash builds up in your mouth.
