Maynilad Water Services, Inc. (Maynilad) serves 9 million people in western Manila. Population growth outstripped the 130 year old infrastructure's capacity to effectively supply potable water.


About 3 million people lacked a connection to the municipal water system and millions suffered intermittent supply or very low pressure.


The non-revenue water (NRW) level before the project was about 67%, or more than 1,500 million liters per day (MLD).


Project Goal

The purpose of the project is to significantly reduce NRW levels, improve efficiency and increase billed volume.


Project Scope

Miya opened an office within Maynilad's newly appointed NRW Reduction Office to implement the ativities for this program including:


  • Water audit
  • Development of comprehensive NRW strategy
  • Establishment and commissioning of District Metered Areas (DMAs) throughout the service area
  • Meter management - meter selection, installation, calibration and maintenance
  • Large scale pressure management program
  • Establishment of leak detection unit and teams; active leak detection activity
  • NRW training for Maynilad personnel
  • Implementation of Netbase water distribution and NRW management software

Financial Highlights

US$ 17 million, out of which 20% are performance-based.


The scope of the project also involves capital improvement investments by Maynilad of around US$ 400 million.


Results (thru 2013)

  • NRW reduced from 1,572 MLD (67%) to 744 MLD (38.4%)
  • 2.5 million additional people connected
  • Maynilad's net income tripled
  • 24/7 water service increased from 65% to 96% of the population
  • The number of customer accounts increased from 730,000 to approximately 1,010,000
  • Over 650 km of flawed pipes were replaced
  • Local jobs were created - 450 engineers were trained and certified in NRW reduction work; local companies were contracted for all necessary work to support and supplement the project
