Why doesn't the Catholic Church serve Holy Water during Lent?

The Catholic Church does not 'serve' Holy Water at any time during the year. Holy Water is usually available at the entrance to a church so that a person can bless himself when entering or leaving. After the Eucharistic celebration on Holy Thursday evening, the Holy Water fonts are customarily emptied until the Holy Saturday Vigil Mass with the blessing of the new water.. Also, any adornments throughout the Church are either removed or covered with purple velvet. The Eucharist that was consecrated during the Mass is removed to an altar of reserve, usually apart from the sanctuary. This is a time of solemn mourning and any hint of celebration is removed.
