Made in the USA, VPC septic tanks are manufactured by means of a rotational molding process which produces a 1-piece, seamless watertight tank. It's HDPE, ribbed design provides superior structural integrity and renders it unaffected by soil and sewage chemicals and gases, while remaining light weight enough for two people to transport it. VPC septic tanks are for underground use only, must be kept full at all times, and includes a 20 in. manhole opening.
