Paranaguá Saneamento will introduce a revised printed water bill format from January 2026, the company announced. The change affects only the physical, paper version of invoices at this stage; the digital statement will remain as it is today.
Paranaguá water bill model changes
The redesigned invoice responds to new national tax rules tied to the planned roll‑out of the Electronic Water and Sanitation Invoice, a fiscal document that will become mandatory for water and sanitation concessionaires. The new layout adds dedicated fiscal fields, including a specific area reserved for the Electronic Water and Sanitation Invoice, allowing customers to identify and access the fiscal note issued by the utility.
Officials said the federal implementation date for the Electronic Water and Sanitation Invoice, originally expected in January 2026, has not yet been finalised. Until the electronic system is activated, the fields added to printed bills may remain blank. Paranaguá Saneamento has pledged to keep customers informed through its official communication channels about any timing updates.
The utility stressed that the revision is strictly cosmetic and administrative. Customers will see no change to due dates, tariff structure or available payment options. Email distribution of billing information will continue for customers whose contact details are up to date.
Customer guidance and fraud prevention
To avoid scams, Paranaguá Saneamento advises customers to be cautious if they receive invoices that do not match the new standard. If an invoice looks different or suspicious, customers should not make any payments and should contact the concessionaire through official channels for verification. The company also recommends that customers update or review their registration on the Digi Iguá platform via the Digi Iguá app or digiigua.igua.com.br to ensure they receive email notices.
