Made in the USA, VPC cistern 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. VPC cistern tanks are FDA approved and BPA-free and are ideal for fresh water storage, especially when water needs to be hauled in or if a well does not meet consumption needs.
