Instituto Água e Saneamento (IAS) is a nonprofit civil organization in Brazil with a mission to ensure universal access to water and sanitation throughout the country. Their focus is on increasing access to sewage treatment services, and they achieve this through research, mobilization, and coordination among various stakeholders from the social, public, and private sectors. The IAS works to elevate water and sanitation to the forefront of discussions on human rights, climate crisis, inequality reduction, and the provision of environmental services.

With a bottom-up approach, they collaborate with municipal governments, technical experts, companies, and civil society organizations to develop and disseminate solutions for water security in vulnerable places. The IAS also advocates for the human rights to water and sanitation and emphasizes the need for comprehensive, culturally sensitive, and environmentally conscious approaches tailored to each community and municipality. They strive to contribute to concrete policies that ensure more people have access to sewage treatment services, promoting scale and impact.

With a focus on climate crisis, the IAS recognizes the urgency of sanitation in guaranteeing water security and mitigating the impacts of extreme weather events
