Calumpang River
Calumpang River is a major river in eastern Batangas, Philippines, and is sometimes called the Nile of Batangas. It forms the southeastern boundary of Poblacion, Batangas City, and flows south into Batangas Bay about 2 kilometers east of Batangas Port.
The name may come from the Sterculia foetida tree, locally called calumpang or kalumpang. Local legends tell of logs floating in the river and of a Holy Infant Jesus statue found on a log after a storm; the statue’s discovery is remembered with a floral procession and boat races on January 16, Batangas City’s feast day.
The river is classified as Class D, meaning its water can be used for agriculture and manufacturing only after treatment. Pollution comes from direct disposal of household and livestock wastes and untreated sewage. Efforts to improve the river include the Calumpang River Rehabilitation Campaign.
Its source is in Rosario, Batangas, and its mouth is in Batangas Bay. The river drains a basin of about 472 square kilometers.
