The knowledge base, experience, the range of water treatment and distribution systems and an abundance of technical, commercial, financial and sociological data at NWSDB, provides a most conducive platform for multi disciplinary research for the progress of the Water & Sanitation sector.

The basis for our R&D; spurred by the objective of achieving outstanding outcomes such as publications in high index journals and conferences, improvements to products and processes; and subsequently, new inventions and patents.

Our Deliverables

  • Formulating mechanisms to create partnerships/ collaborations with national/ international government/ non-government universities, research institutions and manufacturers of products applied in the industry.

  • Creating a strategy for funding postgraduate research. Increasing support for early career researchers.

  • Creating a knowledge hub which provides best practices, research, laboratory services support and training for interested organizations, universities, innovators, educators across the multiple sectors of water and sanitation.

  • Promoting alternative sources such as rainwater harvesting at end user level for places with water scarcity.

  • Introducing modern technology, for example: Connected appliances and Valve operations through the Internet.
