Once the City Sanitation Plan (CSP) is ready, it is time to plan and implement specific interventions that are in line with the strategies defined in the CSP for the immediate, short, medium and long term. The interventions are not only the construction of infrastructure, but also the carrying out of programmes for the strengthening of the institutions, capacity development, awareness generation and behavioural change, developing monitoring and evaluation systems, among other. This module describe the role that the CSP should play during the planning and carrying out of intervention at the city level, as well as State Level.
