Q. 1. What is the purpose of the Sacrarium in the Catholic Church?

A. 1. The Sacrarium (synonym to "Piscina") is a special sink located in the Sacristy of the Church. It purpose is to receive the water from the washing of the sacred vessels and linens. While ordinary sinks drain into the sewer system, the Sacrarium or basin, drains directly into the earth, thus displaying reverence for what is holy and sacred.

Also disposed in the Sacrarium are the ashes from burned religious objects and the holy oils of the previous year.
