The project seeks to co-design, share experiences and innovate to prevent industrial and domestic discharges from collapsing sanitation and sewage networks, threatening the environment and socio-economic development. The project has 4 objectives: governance (obliging and sanctioning but also advising the industry), technology (pre-treatment systems in industries, sanitation and sewage networks), environment (minimizing damage from anomalous spills that block the biological processes of purification , with the risk of discharging insufficiently treated water) and sensitization of end users.
