A federal court in Campo Grande has ordered the Brazilian Union to guarantee a continuous supply of treated, potable water to indigenous communities across 19 municipalities in Mato Grosso do Sul. 

Following a civil public action initiated in 2021, the ruling mandates a minimum daily supply of 110 liters of water per person. To achieve this, the Union must collaborate with state and municipal governments to build permanent infrastructure, including reservoirs, distribution networks, and household connections. The court also requires bimonthly maintenance to prevent service interruptions. 

Authorities have 90 days to begin identifying communities lacking access and implementing these measures, with a daily fine of R$ 5,000 set for non-compliance.
