The Regulasan Project is carried out under the Interáguas Program (of the Brazilian Water and Sanitation Agency - ANA), which is the result of international cooperation between the Brazilian Government and the World Bank - financing agent and technical partner of said Program. 
Also as a partnership via international cooperation is the Inter-American Institute for Cooperation on Agriculture (IICA), which also acted for the implementation of Regulasan.

The project deals directly with subnational public regulatory agencies, with the provision of selecting 5 agencies through public selection for participation in the project.

Regulatory Agencies for water supply and sewage services

Regional (five Brazilian states)

2015 to 2018

Public selection of 5 (five) agencies regulating water supply and sewage services, to be the beneficiaries of the contracted technical assistance, seeking, in the selection, the representation of the multiplicity of existing arrangements in the country by scope of action (State, Municipal and Consortium):
• State Agency for Regulation of Public Services of Mato Grosso do SUL – AGEPAN/MS (acronym in Portuguese);
• Tocantinense Regulatory Agency – ATR/TO;
• Municipal Agency for Regulation of Delegated Public Services of Cachoeira do Itapemirim/ES;
• Regulatory Agency for Sanitation Services of the Piracicaba, Capivari and Jundiaí Rivers Basins – ARES-PCJ/SP; and,
• Intermunicipal Sanitation Regulatory Agency – ARIS/SC.

Among the regional training, the Project comprises four activities, in the cities of Campo Grande-MS, Palmas-TO, Americana-SP and Florianópolis-SC, each with specific themes of interest to the regulation of basic sanitation.

The selection process was conducted through a public call for proposals published on the platforms of the project’s promoting entity: Public Call No. 33/2015.

The agencies that participated in adhering to the Program Contract and the proposal in the Regulasan Project, which it uses, provided for the use of indicators extracted from the SNIS (National Sanitation Information System, acronym in Portuguese) to measure the results achieved with the project. This information was presented by each agency in its annual management reports.

The Project is developed under the Water Sector Development Program – INTERÁGUAS, as a result of the loan agreement granted by the World Bank. For the implementation of the Program, the Ministry of Cities had a Technical Cooperation Project with IICA – Inter-American Institute for Cooperation on Agriculture (Project BRA/IICA/13/005), through which Regulasan was implemented.
