The successful pilot of a rehabilitation project for a tributary of Manila's main river is a step toward restoring its former glory.

Overview

Once a source of drinking water and fish, Manila's Pasig River was declared biologically dead in 1990 after decades of neglect. Numerous attempts by the Philippine government to rehabilitate the river in subsequent years failed. In 2009, the government launched a program to rehabilitate the Estero de Paco, one of the river's 50 tributaries. But despite these efforts, the water continued to smell and the water quality remained below the Class C standard, which is the minimum considered safe for aquatic life, recreation, and post-treatment manufacturing processes.

In 2012, the government sought Asian Development Bank (ADB) assistance to further rehabilitate the river. ADB responded with a technical assistance (TA) project that focused on wastewater treatment. It was a project ADB and the Pasig River Rehabilitation Commission (PRRC), the agency tasked to oversee the river's rehabilitation, hoped could be replicated to rehabilitate the entire river system.
