Sanitation and water infrastructure efforts in the Jundiaí region have focused on both localized network expansions and large-scale environmental recovery.

In the Ivoturucaia region, DAE Jundiaí initiated a water network extension project on Avenida José Mezzalira, investing R$ 119,000 to install 530 meters of network for approximately 50 families. This is part of broader sanitation works across various neighborhoods including Roseira, Traviú, and Jardim Planalto.

On a larger scale, the Rio Jundiaí has transitioned from a heavily polluted waterway to a national benchmark for river recovery. This transformation follows decades of integrated sanitation investments and collaborative municipal actions. A significant milestone occurred in 2017 when the river became the first watercourse in Brazil to have its entire length reclassified from Class 4 to Class 3.
