ESRISS is a Swiss State Secretariat for Economic Affairs (SECO) funded research project at Sandec that deals 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), aims at developing decision-making tools and strategies for the wide-scale replication of small-scale sanitation systems. As a parallel research component of the Integrated Sanitation & Sewerage Infrastructure Project (ISSIP), launched by the Government of Egypt in cooperation with the World Bank, it complements the establishment of centralised treatment plants in three Governorates of the Nile Delta region. ESRISS is coordinated by Philippe Reymond, who is based in Cairo.
The objective of ESRISS is to address the following research questions:
- What are the challenges and success factors of past decentralised sanitation approaches in the Egyptian context, and why?
- 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?
- What key features in the enabling environment are necessary to scale up small-scale sanitation in the Nile Delta? What are the ways forward?
- How economically viable is a decentralised treatment system compared to a traditional centralised system in terms of capital, operation and maintenance costs?
