Tubig Para Sa Barangay (TPSB) is the flagship programme of Manila Water, providing sustainable water services to the urban poor. It created a win-win solution for the company and its customers by overcoming legal, technical and economic constraints previously considered insurmountable. As a way of communicating and addressing customer needs, public consultations were held with local community partners (fondly termed as kasangga) acting as communicators and influencers in behalf of Manila Water. In cases where pipelines cannot be laid due to narrow road networks, group metering or bulk meter schemes were provided to low-income communities, where kasanggas play a key role in establishing site-specific mechanisms for distributing water and billing. By providing access to water communities previously denied such service, Manila Water has empowered the poor at the bottom of the pyramid and manifested its commitment to inclusive growth.

Complementing the TPSB Programme is the Lingap Programme which improved water access in public service institutions frequently patronised by the urban poor, such as schools, hospitals, public markets, city jails and orphanages. This ensured that people from the urban poor would still have access to safe drinking water and promote proper sanitation even outside their homes. As of the end of 2014, 355 public service institutions have benefited from this programme.
