Models and Values of Fees and Incentives for Financing Sustainable Urban Drainage

Challenges are observed worldwide in the cost of urban drainage through fees compromising the sustainability of its management. Strategies are needed for greater involvement of users of the drainage system, assuming their responsibility for the cost of this system and collaborating with the system on their properties through the containment and delay of the surface runoff of rainwater to the public network from sustainable technologies. Incentives for these users to implement technologies that minimize the outflow of their properties can be an essential strategy for implementing fees. Therefore, this work aimed to evaluate, through a systematic review (SR), the values and methods of drainage fees and incentives for urban environmental services provided by users of drainage systems. The SR was developed from a search on the Web of Science (WoS) and Scopus platforms, whose data were analyzed using the StArt system. Among the 199 articles studied and published between 2010 and 2021, it was possible to relate fees and incentives practiced. Concerning fee models, the ERU method (Equivalent Residential Unit) was predominant. Regarding the incentive models, the most used was tax reduction.
