When the world renowned gigantic Nagarjuna Sagar Dam was under construction, thousands of engineers and other employees settled down in Nagarjuna Sagar along with their families. These employees approached Sr.Ferdiando, JMJ the then provincial superior through Rt. Rev. Ignatius Mummadi, the Bishop of Guntur to extend their services. At their persistent request Sr. Ferdinando sent Mrs. Lily Swamy one of the teachers of St.Joseph's English Medium School, Guntur to start and manage the English Medium School at Nagarjuna Sagar as the province was short of sister personnel just then.

St. Joseph's upper primary English Medium school, Hill Colony was started in 1961-62 with classes I to VII, later they were recognised in 1969. This school building was inaugurated on 4th August, 1967 by our beloved Prime Minister, Late. Smt. Indira Gandhi and was blessed by Rt. Rev. Dr. A. Beretta Bishop of Warangal Diocese.
