Seed Project: Informed Sanitation and System Choices for CWIS
Piloting SaniChoice and the Citywide Inclusive Sanitation Planning (CWIS-P) Guideline in Nepal
Today, half of the global population lack access to safe sanitation globally. Most of them in developing urban areas where conventional centralized sewer systems are not viable. Improved planning practices are urgently needed. Citywide Inclusive Sanitation is an framework for providing inclusive access to adequate and sustainable sanitation services, including the safe, effective, and sustainable management of all human waste along the whole sanitation service chain.
To develop a strategic CWIS plan requires a strategic multi-stakeholder planning process. One challenge remaining is the identification of sanitation technologies along the sanitation value chain combined with viable financing and operation models. Identifying a locally appropriate and sustainable combination of sanitation technologies and system configuration is a complex multi-criteria decision-making problem involving a growing number of technical solutions, multiple criteria, local conditions, and trade-offs. To enable practitioners to make a systematic and informed choice Eawag, with its partner in Nepal and Ethiopia, has developed SaniChoice, an open-source online tool for informed sanitation technology and system choice as an input into the decision process. In this project, we will test SaniChoice together with a locally developed draft guideline for CWIs planning. With this, we hope to learn more on how best to apply SaniChoice as well as to improve the existing guide with specific information for each step of its implementation.
The project is a strategic opportunity to contribute to the development of best practices in CWIS planning in Nepal. This contribution is made through the development of knowledge on how to implement CWIS planning including SaniChoice. This knowledge is directly transferrable to many other municipalities in the country and the region.
