Sarwanam initiated street theatre in Nepal by performing two plays, "Hami Basanta Khojiraachau" (We are searching for the spring) and "Samapta Asamapta" (End unend) in A.D 1982. By breaking the strong conservative myth that theatre could not be performed without a stage, lights, curtains, props and all such technical equipments, Sarwanam marveled everyone by showcasing a heart touching play beneath the colossal sky. The play was performed in Tribhuwanm University, Kathmandu and was directed by Sarwanam's founder and director Ashesh Malla.

In A.D 2002, Sarwanam organized a poetry recitation program, "Sarwanam Poem 2002" by Nepal's 24 leading poets like Rastra Kabi (Nation's Poet) Madav Prashad Ghimire, Ishwor Ballav, Tulasi Diwas and Dwarika Shrestha. Theatre critic Abhi Subedi had critically spoken at the event.

SARWANAM is the pioneer of the street theatre in the country. With a view to bridge in the gap between the audience and actors and to deliver the essence of drama in the rural Nepal where Drama-infrastructure is lacking, it brought down the theatre to street. So, to commemorate the day when the street drama was first performed in the country by SARWANAM, it celebrates a Weeklong Street Drama Festival nation wide from Bhadra 20 to 27 annually.
