Practices and challenges :Environmental framework for wastewater planning

Bigger systems will have economies of scale, but smaller
systems are as efficient and effective.
Densely packed urban centers makes it challenging tofind a suitable site for WTP facilities.

ProgramConference on Watershed Management forControlling Municipal Wastewater in South East Asia

•July 28-29, 201621

From water quality mgt. to river basin. Revisiting the Philippine Water Code.

• Improved information on rivers and watersheds.
• Advocacy and capacity building: Inclusion of a blue environmental
framework to water service providers on wastewater and septage
planning• Creating an incentives mechanism : ‘benefits to host communities’• Developing the market of de-sludgers.
• Convergence of national-led programs
