| Abstract: | As a developing country, Brazil has to deal with a lack of basic sanitation. One of the major challenges is the treatment of wastewater. While 94% of Brazilian municipalities have stormwater systems, only 55% are connected to a wastewater system. To help improve the current situation, this study estimates the costs for implementing an intermediate solution, which is designed to ease the transition towards a separate wastewater treatment system. This solution utilizes a combined sewer system approach in areas where stormwater systems have already been implemented. A case study was carried out assessing two possible alternatives for a wastewater treatment system with data from the city of Joinville. Both alternatives are separate systems but one has a combined system as an intermediate solution. The results show that the alternative with an intermediate combined system will reduce the short‐term financial burden on governments in comparison to the separate sewer system approach. |
