Watershed Management


Manila Water recognizes that ensuring the sustainability of its water supply means protecting its source — the Ipo, La Mesa and Upper Marikina Watersheds. To ensure the productivity and sustainability of these watersheds, Manila Water has continuously implemented various watershed management initiatives in partnership with relevant key stakeholders. 

Healthy, well-managed watershed ecosystems will help secure water supply. Manila Water seeks to manage these critical watersheds by implementing sustainable forest management approaches, soil and water conservation techniques, and collaborating with stakeholders for effective forest protection. Watershed management will help reduce greenhouse gas emissions as a result of deforestation and forest degradation, increase carbon sink capacity, and improve water flow regulation. 

To date, a total of over 149 hectares in the Ipo watershed area has been reforested under Manila Water’s Adopt-a-Watershed program.

Toka Toka


Toka Toka is the first and only environmental movement in the country that advocates proper management of wastewater (used water) in every household as an important share (or Toka) in reviving our rivers and waterways. Toka Toka believes that if this value shift happens in each household or sector, and is upheld actively by individuals and institutions, rivers and waterways will be freed from the vicious cycle of pollution.

A joint project between Manila Water and founding partners, Asian Development Bank (ADB) and ABS-CBN Foundation, Toka Toka's goal is to move the people into embodying these four ownable acts:

  1. Encouraging solid waste management and segregation;
  2. Desludging of household septic tank every five years;
  3. Connecting all households to a proper sewer line; and
  4. Educating the community on proper wastewater management and the environment.

Since its inaugural partnership formation in 2012, there are now over 25 institutions and companies who have signed up as Toka Toka partners.
