Orangeburg is a fiber pipe, essentially tarred wood pulp, installed heavily in the postwar decades and still present under older Golden neighborhoods. It does not crack like clay; it deforms, flattens, and delaminates with age and root pressure, which changes what maintenance can promise. A snake or jet can clear a round clay line for years; in a flattened Orangeburg section, clearing buys shorter intervals each time, and the honest scope says so. The camera distinguishes the two in one pass, which is why the inspection at $125 to $500 precedes any serious Golden sewer money: the material is the forecast.
