Oh, yeah. The big bad. Manufactured by Cranszold from 1971-1990, the S.E.W.E.R., or Sewage, Evacuation, Water, Effluence, & Reservoir Tube was, and still is in many respects, the standard for sewer systems and doomsday bunker tunnels. Over 70% of those placed into service are still in use today, but are slowly being replaced by the Makra One-Vs.
