Philippines’ MMDA Unveils Bold 50-Year Master Plan for Integrated Metro Manila Drainage

The Metropolitan Manila Development Authority (MMDA) has announced an ambitious 50-year master plan to integrate and standardize drainage systems across the metropolis. Set to kick-start in the next year, the initiative aims to establish a design blueprint for the drainage infrastructure in the National Capital Region with a focus on consistent water flow and prevention of disruptions due to varying drainage system sizes.

As outlined by MMDA acting Chairman Romando Artes, the master plan will specify the necessary size and reach of the drainage infrastructure to ensure a free-flowing water system. The plan will also factor in the required depth for creeks and the potential resettlement of informal settlers residing along the waterways.

The 50-year timeline has been chosen to incorporate observations of weather patterns and rainfall volume over an extended period, facilitating comprehensive and effective planning. This long-term approach will enable the project to adapt and respond to changing climate patterns, thereby enhancing the city’s resilience.

The World Bank has confirmed funding for the project via a loan. This significant project is a crucial step towards improving Manila’s infrastructure and addressing water management issues. It also marks a considerable advance towards the city’s resilience to climate change impacts.

The primary objective of the master plan is to enable a consistent flow of water throughout the metropolis. Inconsistent drainage system sizes often cause disruptions, leading to water stagnation and subsequent issues. By standardizing the size and design of the drainage systems, MMDA aims to mitigate these issues and ensure a steady flow of water.

Preventing Future Disruptions

Another key aspect of the plan is to prevent future disruptions caused by irregularities in the drainage system. By identifying the necessary size and extent of drainage infrastructure, the plan will ensure that the systems are equipped to handle the city’s water flow efficiently. This will significantly reduce the chances of unforeseen disruptions and help maintain a steady flow of water.

Addressing the Challenge of Resettlement

The master plan also addresses the challenge of resettling informal settlers residing along the waterways. The MMDA recognizes the importance of ensuring the safety of these communities and will consider their resettlement as part of the plan. This consideration underscores the holistic and inclusive approach of the master plan.
