The site we now know as the filling station started first as a fuel reservoir, which came out of necessity. In the late 1970s, Enugu region of Nigeria witnessed great scarcity of fuel which as a result impaired many activities both in the seminary and the wider society. At the death of the then Bishop of Enugu Diocese, Most Rev. Godfrey Mary Paul Okoye C.S.Sp on March 17, 1977, the Bishops who needed to attend the burial had to make arrangements for fuel to serve them through the journey and back to their various destinations; this, therefore, necessitated the establishment of the reservoir.
Progressively, in 1994, under the rectorship of Msgr. John Bosco Akam, the Seminary officially developed and commissioned the reservoir into a filling station with a capacity of 9,080 litres of fuel. This filling station served the seminary during those periods of fuel scarcity, which was evidently unfavorable to the Nigerian transport system; hence the filling station was beneficial to the formators and for domestic usage. This continued to serve its purpose until around 2004, when the then rector, Very Rev. Fr. Dr. John Okoye (presently, Bishop of Awgu Diocese), closed down the filling station as a result of abuses.
