Building infrastructure is one of the pillars of the organization's activities and one of the most important, as it provides an alternative to improving sanitary conditions in communities. SUSAMATI's constructions are user-oriented. Therefore, in the construction diagnosis and design of the project, we prioritize the involvement of local leaders and potential users of the infrastructure to understand their expectations about the outcome. In addition to user engagement, we always want to incorporate the core principles that are part of our building values, such as sustainability, community empowerment and innovation. To date, the organization has built more than 30 family toilets and 10 public toilets that have benefited more than 10,000 users.
