Asia and Pacific

In the Asia-Pacific region, GWOPA works in close cooperation with a number of regional and national platforms. 


Established in 2008, WaterLinks is a fully independent, non-profit organization operating across Asia. Principal WaterLinks activities are:

  • WOPs support and facilitation (over 70 WOPs to date);
  • Regional capacity building program development (e.g. training, toolkits, manuals, studies); and
  • Knowledge management and networking.

GWOPA collaborates with Waterlinks to facilitate WOPs and develop thematic materials.

In the Pacific region, GWOPA has been working in collaboration with the Pacific Water and Waste Association (PWWA) to respond to demand by the water and sanitation utilities of these small island developing states for increased regional exchange and cooperation. PWWA is a member of GWOPA’s International Steering Committee Meeting since 2009.

The platform was launched in September 2010 at the Pacific Water Conference in Port Moresby, Papua New Guinea. The platform’s secretariat is hosted by PWWA, the regional association of organisations operating in the water and wastewater sectors whose mission is the delivery of quality water-related services that enhance the wellbeing of people throughout the region.

The Pacific Water and Wastewater Association (PWWA) is a not for profit organization and was established in 1994 to support the Pacific region in meeting all water challenges both at the national and regional level.  From voluntary membership that brought together utilities and people dedicated to bringing Pacific water issues to the fore, PWWA grew over time to an established regional organization with its permanent Secretariat established and recognized in 2017, following some dynamic reforms.  Its headquarters is in Samoa with 4 full time staff including the Chief Executive Officer.

PERPAMSI (Indonesia)

The national platform for WOPs in Indonesia is PERPAMSI, an independent water supply association founded in 1972. As of 2019, PERPAMSI’s members have reached 438 water utilities, most of which are public water utilities belonging to the local/regional governments.

The main role of PERPAMSI is to assist the government of Indonesia and support capacity development of its members in providing better services to customers. Water Operators’ Partnerships (WOPs) are a tool used by PERPAMSI to support its members’ performance improvement. As a WOP facilitator, PERPAMSI encourages its members to help one another in building their capacity based on the spirit of solidarity, having organized 59 national WOPs since 2011 as of today.
