Coordinated and completed in 2022 by the Municipality of Suzano (SP), the Municipal Plan for Drainage and Management of Rainwater of Suzano (PMDMAP) carries out an extensive mapping of the municipality, identifying everything from roads, properties and occupations to the type of ground cover, basins and areas at risk for human occupation.
The study covers 45 areas (divided into several sectors) and is an important municipal management tool in several aspects, such as: urban occupation, transport and road development, social programs and environmental education.
In addition, the PMDMAP identifies regions subject to flooding, flooding and landslides, helping the city hall to intervene in critical areas and thus prevent accidents.
Consisting of a diagnosis by sector, the plan provides specific recommendations for solving problems for each one of them.
These may include garbage and debris cleaning services, improvements to the surface drainage system (rainwater, wastewater and/or sewage); earthworks to adjust or reduce the slope, drainage works and surface protection; implementation of containment structures (gravity walls, curtains, etc.), earthmoving services; implementation of surface vegetation protection (grasses) on slopes with exposed soil; cleaning and desilting of the drainage channel and even definitive removal of houses in the sector.
The PMDMAP, started in 2017, was funded by FEHIDRO (State Water Resources Fund), through the CBH-AT (Alto Tietê Basin Committee), and carried out by the companies Ieme Brasil and Base for the Suzano City Hall.
