Extreme hydrological events have become increasingly frequent, causing disasters resulting from floods and landslides in important Brazilian cities. 

The need for investments in drainage infrastructure has guided decisions among public managers at the municipal, state and federal levels, as well as society as a whole, in the search for measures to offer safety and a better quality of life for the population. Drainage works, which generally involve high costs, require advanced methodologies to increase their efficiency and, consequently, guarantee results. Elgayer Engenharia, through a highly qualified team and by employing innovative technology with the use of computational tools for the analysis of hydraulic and hydrological scenarios, enables the development of efficient and cost-effective projects for drainage engineering solutions.
