and planning

The Citywide Inclusive Sanitation Services Assessment and Planning (CWIS SAP) tool helps decision-makers compare the outcomes of different sanitation interventions or investments.

The tool analyzes and illustrates how each proposed intervention is likely to affect the equity, financial sustainability and safety of sanitation services in an urban area.

The CWIS SAP tool is designed in collaboration with regulators and service providers to assist in evaluating a variety of options and prioritizing those that cost-effectively and equitably expand access safely managed sanitation.

About CWIS

Citywide Inclusive Sanitation (CWIS) is a public service approach to planning and implementing urban sanitation systems to achieve outcomes of Sustainable Development Goal 6: Safe, Equitable, and Sustainable sanitation for everyone in an urban area, paying special attention to the needs of the poor, the marginalized, and women and girls.

Three core functions – Responsibility, Accountability, and Resource Planning and Management – are required of any effective sanitation service delivery system to achieve the outcomes of citywide Equity, Safety, and Sustainability. The CWIS framework allows for and encourages flexibility in how each of those functions are achieved in different contexts.

CWIS focuses on outcomes and system functions rather than specific system designs. Sanitation authorities may and must consider the range of possible technologies, service and business models to improve outcomes in their city. CWIS SAP is a tool to help them do so.

About the
CWIS SAP Project

The CWIS SAP tool is designed to help decision makers improve city-level equity, safety and sustainability outcomes in the context of limited resources and highly complex, often fragmented, governance and market dynamics. It facilitates effective resource planning by providing sanitation authorities with a means of systematically considering a range of scenarios, evaluating the tradeoffs associated with each of them and selecting the option(s) that cost-effectively promote universal access to safely managed sanitation.

The CWIS SAP project team has collaborated with national regulators and sanitation authorities to develop the tool and test it in Lusaka (Zambia), Nakuru (Kenya), and Khulna (Bangladesh). A second round of testing is ongoing in Dar es Salaam (Tanzania), Kampala (Uganda), and Trichy (India). These experiences have informed the design of the tool and shaped how it is expected to be used for regulatory, investment, and business plan decision-making. The testing process is also informing the need for and direction of investments in data collection and management systems.

Experiences from the six early adopter cities – which cover a range of planning needs, data ecosystems, and structures for sanitation service delivery – are being used to guide plans to scale up use of the tool and support its institutionalization in national decision-making processes. National partners are expected to facilitate replication with new cities and utilities, in their countries and at the regional level.

The Bill & Melinda Gates Foundation is supporting the work of the CWIS SAP project, and is developed by Athena Infonomics in collaboration with Eastern and Southern Africa Water and Sanitation Regulators Association (ESAWAS), and Aguaconsult.
