The Safe Water Program Phase II is a 3-year project funded by the Swiss Agency for Development and Cooperation and Aqua for All, with the aim to increase access to safe water at global scale and to contribute to the human right to water through integration of the business models in the national regulation. Supported and documented businesses are ECCA and MinErgy in Nepal, PakoSwiss in Pakistan, Spring Health and TARA in India, Tinkisso in Guinea, and Hydrologic in Cambodia.

Desalination technologies typically require high energy inputs, as well as specialized maintenance procedures, to function sustainably – rendering them inappropriate for water production in low-income areas. The focus of this paper is the development of a ‘Road Map’ for scalable, low energy-input solutions for small-scale desalination.
