In Porto Alegre, water supply in 21 neighborhoods may face total interruption or low pressure due to maintenance at the Moinhos de Vento Water Treatment Plant. The shutdown is necessary for CEEE Equatorial to complete a dual power supply project intended to increase energy security for the facility.

The R$ 18 million infrastructure project includes over 44 kilometers of work and 68 remote-controlled reclosers. This system is designed to provide automatic power switching between two distinct sources to prevent water shortages, sewage overflows, and flooding. Further planned interventions are scheduled for the Menino Deus and São João stations on September 9 and 15.
