Abstract

Intense urbanization alters the water balance and impacts stormwater runoff, making Urban Stormwater Drainage and Management (USDM) services essential to mitigate the effects of heavy rainfall. This article analyzes the economic and financial situation of USDM services in Brazil based on data from the National Sanitation Information System (2015-2022) and addresses legal, institutional, and technical challenges for implementing an efficient charging system. A simplified financing model adaptable to various cities and regions is also proposed. The results show that of the 24 municipalities claiming to charge for USDM services, only one actually does. These services are mostly provided by direct public administration, with funding for maintenance, operation, and system expansion primarily coming from the general budget. While implementing charges could enhance service delivery, restructuring the institutions responsible for USDM is also necessary.
