The African Union Heads of State and Government Summit of July 2008, mandated the African Ministers’ Council on Water (AMCOW) to monitor progress and report annually on the status of water and sanitation sector in Africa. With financial support from Africa Water Facility through the Africa Development Bank, AMCOW mandated UNEP-DHI to develop a web-based reporting system, the Pan-African Water and Sanitation Sector Monitoring and Reporting System (WASSMO) in October 2015. 

 WASSMO is the first ever continent-wide automated web-based system that exclusively captures data on water and sanitation across the 55 Member States of the African Union using harmonised progress indicators. It allows AMCOW to monitor progress and report on the implementation of the African Union commitments expressed in the 2008 Sharm El-Sheikh Commitments on water and sanitation taking into account several international agreements, the Africa Water Vision 2025 and the Africa Agenda 2063, as well as Sustainable Development Goal 6 on clean water and sanitation. 

WASSMO for AMCOW is currently hosted by AMCOW and maintained with the support of UNEP-DHI. 

Following the successful implementation of WASSMO for AMCOW, UNEP-DHI was mandated in 2018 by ECOWAS to adapt WASSMO for the West Africa region. Together with Water Resources Coordination Centre of ECOWAS, UNEP-DHI implemented a regional version of WASSMO with specific indicators for the ECOWAS region.
