Klaas Schwartz PhD, MSc

Associate Professor of Urban Water Governance


Klaas Schwartz joined IHE Delft in 1998 where he is currently Associate Professor Urban Water Governance. His main research interests concern the reform of public water utilities, service provisioning to low-income areas (‘pro-poor services’) and informal water services provisioning. In his work on utility reform and water provisioning in low-income areas, a strong emphasis is placed on trying to understand the provisioning of services from the perspective of service provider (the utility or informal provider) and how these decisions impact access to water services by different users.

Klaas Schwartz has been involved in research, education and training activities in the field of water services management and governance in various countries in Asia, Africa, Europe and Latin America. In addition to his position at IHE Delft, he is a visiting researcher at the Amsterdam Institute for Social Science Research of the University of Amsterdam.

Other information


Performance Enhancement of Water utilities in Kenya through benchmarking, collective learning and innovative financing (PEWAK) – Within this project, the input of the Water Services Management group concerns the analysis of strategies that water service providers in Kenya design and implement to provide water services to low-income areas. As part of this activity, a benchmarking system to compare strategies and performance of water service providers in serving low-income areas is developed and implemented.


Boosting Effectiveness of Water Operator Partnerships (BEWOP) - This project aims at assisting and enhancing the knowledge transfer and change processes, and hence to foster the effectiveness of water operator partnerships (WOPs). The BEWOP project is a collaboration of the UN-Habitat Global Water Operators’ Partnerships Alliance (GWOPA) and UNESCO-IHE. BEWOP is targeted towards the development of guidelines, trainings and tools that allow water operators to develop more effective partnerships to improve provisioning of water services.
