On New Year’s Eve, the Companhia de Saneamento do Paraná (Sanepar) adopted targeted reductions in distribution pressure across parts of the Paraná coast after an exponential surge in water consumption. The measure, introduced at around 15:00, affects Matinhos, Guaratuba and Pontal do Paraná and may cause short, localised interruptions as the operator prioritises broader supply continuity.

Sanepar said the decision was taken to restore reservoir levels while the treatment plants operate at their maximum production capacity. By lowering pressure during predictable peak periods, the utility aims to avoid larger and longer interruptions that would be necessary if reservoir volumes fell further.
The company identified peak demand windows such as lunchtime and the late afternoon, when many holidaymakers return from the beaches and household consumption of showers and taps rises sharply. Sanepar cautioned that some neighbourhoods may see temporary drops in supply, but described the approach as the least disruptive option under the circumstances.
Local authorities and the utility emphasised that 31 December is traditionally the day of highest water consumption on the coast. Sanepar noted that average demand in the preceding week was around 20% higher than the same period last year, and that the coastal region is expected to host more than three million visitors this season.
Operationally, the reduction in pressure is a standard demand-management technique. Lowering distribution pressure reduces flow rates to end points and helps conserve stored water in networks and reservoirs. Sanepar said treated water continues to be supplied at the plants’ maximum feasible rate while distribution is managed to balance supply and demand across municipalities.
For residents and visitors, the immediate impact may include brief periods without running water or noticeably reduced pressure when taps are opened. Sanepar recommended limiting non-essential use during peak hours, prioritising critical needs such as drinking, cooking and hygiene, and storing a small reserve of water when supply is available.
The company also urged customers to report outages or significant pressure loss through its usual channels so crews can assess local issues promptly. Sanepar indicated that teams remain on alert to respond to faults and adapt pressure-management measures as consumption patterns evolve through the evening.
Water utilities often face acute stress in coastal regions during holiday seasons when transient populations swell infrastructure demand. The utility’s measure seeks to provide an operational buffer that protects reservoirs from rapid depletion while maintaining service to the widest possible number of users.
Authorities expect normal pressure to be restored once peak demand subsides. Sanepar reaffirmed its commitment to monitor the situation closely and to communicate changes to the public through official updates. For those planning to stay in the affected municipalities, simple conservation steps and awareness of peak times will help reduce the likelihood of experiencing service interruptions.
Key Takeaways:
- Sanepar implemented a deliberate pressure reduction to manage record water demand on the Paraná coast.
- The measure aims to recover reservoir levels while treated water is supplied at maximum production.
- Sanepar water pressure reduction targets peak hours in Matinhos, Guaratuba and Pontal do Paraná to avoid larger interruptions.
- Residents are advised to limit non-essential use during peak times and report service issues through the company’s channels.
