ESRISS: Egyptian-Swiss Research on Innovations in Sustainable Sanitation

2010 - 2015 • Eawag


To develop decision-making tools and strategies for the scaling up of small-scale sanitation systems


ESRISS is a Swiss State Secretariat for Economic Affairs (SECO) funded research project at Sandec that dealt with the sanitation planning gap in Nile Delta villages which cannot be connected to large centralised treatment plants. The five-year research project (Mai 2010 - April 2015), in partnership with the Egyptian Holding Company for Water and Wastewater (HCWW), aimed at developing decision-making tools and strategies for the wide-scale replication of small-scale sanitation systems. ESRISS is coordinated by Philippe Reymond.

Countries of activity

Location of main activity


- Identify the challenges and success factors of past decentralised sanitation approaches in the Egyptian context

- Identify what technologies and/or combinations of technologies are the most appropriate for the Nile Delta region given the land use, water or wastewater usage and local environmental factors, and how do these affect nutrient recycling and resource recovery

- Develop recommendations to create an enabling environment for the scaling up of small-scale sanitation in Egypt

- Assess the economically viability of decentralised treatment systems compared to traditional centralised systems in terms of capital, operation and maintenance costs


Sanitation in the Nile delta

This video highlights the sanitation situation in the rural areas of the Nile delta and how small-scale sanitation systems can contribute to increase sanitation coverage in the region.
