Heavy rainfall on Wednesday 31 December caused siltation at the Alexandra surface water intake, prompting Paranaguá Saneamento to warn that supply in several local neighbourhoods would be affected. Residents in Alexandra, Toral, Tapera, Rio das Pedras and Ribeirão can expect either low pressure or temporary loss of water while crews carry out maintenance.
Company technicians began work at 14:45 and the maintenance was scheduled to finish by 18:00. Paranaguá Saneamento said that, once repairs are complete, service should return to normal within two hours as the network refills.
Paranaguá water supply restoration plan
The operator described the cause as an accumulation of sediment at the Alexandra intake after an episode of intense rain. Silt and debris can reduce the capacity of surface intakes and disrupt treatment and pumping operations. Field teams focused on clearing the intake and restoring normal flow to the affected mains.
To limit the impact on households, the company advised users to keep the stopcock at the cavalet closed during the repair period. That simple precaution helps households avoid sudden surges that could cause damage or waste water when pressure returns.
Paranaguá Saneamento also reminded the public of existing legal obligations that support resilience to intermittent supply. Municipal and federal regulations require each property to maintain a water tank sized to provide a minimum 24 hours of storage based on the number of occupants. The company noted that those who comply with this requirement are unlikely to see their daily routines disrupted, provided they practice conscious consumption while the system recovers.
The operator expressed regret for the inconvenience and urged the community to avoid unnecessary use of water during the restoration window. Conserving water helps the network recover more quickly and reduces strain on pumping equipment.

Local water networks remain vulnerable to extreme weather events that mobilise sediment and debris. Operators and residents alike are encouraged to maintain preparedness measures, including adequate household storage and prompt reporting of supply problems, to reduce disruption when incidents occur.
