In the heart of the Philippines lies a waterway of immense historical, cultural, and ecological significance—the Pasig River. Flowing through the bustling metropolis of Manila, this iconic river has been both a lifeline and a source of challenges for centuries. However, it wasn’t until relatively recently that concerted efforts were made to address the issues plaguing the Pasig River Basin. In this article, we delve into the timeline and milestones that marked the transformation of the Pasig River Basin into a focal point for environmental conservation and sustainable development.

The Pasig River Basin: A Brief Overview:

Before delving into the timeline of when the Pasig River Basin became a focus, let us first understand its geographical context. The Pasig River, originating from Laguna de Bay, meanders through Metro Manila before emptying into Manila Bay. Its major tributaries, the Marikina River and San Juan River, contribute to its flow and ecological diversity.

For centuries, the Pasig River served as a vital artery for trade, transportation, and livelihoods, shaping the development and growth of communities along its banks. However, rapid urbanization, industrialization, and population growth led to pollution, encroachment, and degradation of the river’s ecosystem.

Timeline of Focus on the Pasig River Basin:

  1. Pre-Colonial Era: Indigenous communities residing along the Pasig River Basin relied on its resources for sustenance and transportation. The river played a central role in the cultural and economic life of these communities, serving as a source of fish, water, and fertile land for agriculture.
  2. Spanish Colonial Period (16th to 19th centuries): With the arrival of Spanish colonizers, the Pasig River became a strategic waterway for trade and commerce. Manila, founded on the banks of the Pasig River, grew into a bustling port city, with the river serving as a conduit for goods and people.
  3. American Period (20th century): The early 20th century saw significant modifications to the Pasig River’s landscape, including the construction of bridges, roads, and flood control infrastructure. However, rapid urbanization and industrial expansion led to increased pollution and degradation of the river’s water quality.
  4. Post-World War II Era: The aftermath of World War II brought further challenges to the Pasig River Basin, as rapid population growth and urban sprawl intensified pressure on its ecosystem. The river became heavily polluted with industrial waste, untreated sewage, and solid waste, earning it the infamous title of one of the world’s most polluted rivers.
  5. 1990s: The 1990s marked a turning point in the focus on the Pasig River Basin, with the Philippine government and various stakeholders recognizing the urgent need for environmental rehabilitation. Initiatives such as the Pasig River Rehabilitation Program were launched to address pollution, improve water quality, and restore the river’s ecosystem.
  6. Early 2000s: In the early 2000s, efforts to rehabilitate the Pasig River Basin gained momentum, with the implementation of infrastructure projects, community-based initiatives, and public awareness campaigns. The construction of sewage treatment plants, riverbanks beautification programs, and solid waste management initiatives aimed to mitigate pollution and improve the river’s condition.
  7. Present Day: Today, the rehabilitation of the Pasig River Basin remains an ongoing endeavor, with various government agencies, non-governmental organizations, and community groups working collaboratively to sustain the progress made. While challenges persist, including illegal settlements, encroachment, and industrial pollution, there is a renewed commitment to safeguarding the ecological integrity of the Pasig River and its surrounding watershed.


The journey of the Pasig River Basin from neglect to focus is a testament to the resilience of nature and the power of collective action. While the challenges facing the river are daunting, the progress made in recent decades offers hope for its revitalization and restoration.

As we look to the future, let us continue to prioritize the protection and preservation of the Pasig River Basin, recognizing its intrinsic value as a natural and cultural heritage site. Through sustained efforts in environmental conservation, sustainable development, and community engagement, we can ensure that the Pasig River remains a source of pride and inspiration for generations to come.
