About Sirsiya River

Sirsiya River
Source – Bihar Govt.
  • The Sirsiya river is a transboundary perennial river flowing from southern Nepal to India.
  • Origin: The river originates from the Ramban Jhadi forest in Jeetpur Simara Sub-metropolitan City of Bara district in Nepal.
  • Course: The river flows through the Bara–Parsa industrial corridor and crosses into India at Raxaul in Bihar.
  • Tributaries The two major tributaries of the Sirsiya river are Kiyasut and Vaudyi, which merge near Birgunj.
  • Merges into: After crossing into India, it flows southward, merging with the Bangari River before joining the Burhi Gandak River in Bihar, contributing to the broader Ganga River basin.
  • Cultural Importance: The riverbank is lined with numerous shrines and temples.
    • It is a central site for the Chhath festival for local communities.
  • Pollution crisis
    • Untreated industrial waste and sewage released by factories have turned the Sirsiya river black and highly toxic.
    • During the dry season, nearly 80% of the river’s flow consists of industrial wastewater, which has destroyed aquatic life and caused serious health problems and cultural decline among riverside communities.
