The document discusses ensuring long-term water security for Mega Manila through improved water governance, infrastructure investments, and exploring synergies. It notes that 60% of the world's population lives in Asia, including Manila which ranks 15th largest city globally. While population grows at 2% annually, water availability and access are threatened without action. The Metropolitan Waterworks and Sewerage System has expanded service through public-private partnerships, serving over 13.8 million people with 24/7 water compared to 5.84 million with only 16 hours previously. Future plans include over $2.2 billion for dams, aqueducts and water treatment to ensure supply through 2037. Exploring synergies between water, power and flood management
