The increase in the number of extreme events as a consequence of climate change has aggravated problems and disasters associated with urban drainage, especially in tropical climates and in locations where urbanization still follows the hygienist model. To deal with these problems, well-designed and executed planning is essential. In terms of legal instruments for urban drainage planning, the only requirement is that municipalities have municipal basic sanitation plans (PMSB), which in turn are often voluminous documents that hinder comparative and global analysis. In this sense, this study aimed to use content analysis to compare and achieve an overview of how urban drainage has been planned. Therefore, the textual analysis software Iramuteq was used to perform quantitative analyses of 280 plans grouped into four Corpora referring to the states of Mato Grosso, Amazonas, Bahia, and municipalities distributed throughout Brazil. The results showed that in the states of Mato Grosso and Amazonas, the plans did not contemplate urban drainage systems with the same relevance as the other sanitation services. Plans were found in which sections of the texts presented the same number of occurrences of terms with spelling mistakes. Among the most frequent terms, none associated with sustainable urban drainage terminologies were observed.
