1. Background

Dalit Jan Kalyan Yuba Club (DJKYC) is a local, non-profit and non-political organization based in Bastipur (Pradip Giri Ashram), Ward No. 14, Siraha, Nepal. Since its establishment in 2000, DJKYC has been working to eliminate discrimination and improve the well-being of women, children, and marginalized communities, while also contributing to Water, Sanitation, and Hygiene (WASH) improvements.

As part of this initiative, a model public toilet facility is proposed along the East-West Highway within Lahan Municipality. Architectural designs and 3D visualizations have already been prepared.
