The lifeblood of the region is the **Damanganga River**.
* **Damanganga River:** Flowing directly through Vapi, the river separates the town into distinct zones before continuing its journey westward to empty into the Arabian Sea at Daman. The riverbanks are focal points for the city's geography. * **Kolak River:** Located just to the north of Vapi, this is another significant waterway that contributes to the region's agricultural and industrial water supply.
