What Sanepar does

Sanepar (Companhia de Saneamento do Paraná) is the state-owned water and sanitation utility of Paraná, Brazil, founded in 1963 and majority-controlled by the State of Paraná (60.08% of voting capital). The company operates under B3 Level 2 Corporate Governance (tickers SAPR3, SAPR4, SAPR11) and is regulated by AGEPAR, delivering treated water supply and sewage collection/treatment across municipalities in Paraná through direct concessions and a growing PPP network. Its core service territory is anchored by the SAIC (Integrated Water Supply System), which serves the Curitiba metropolitan area at 83.78% capacity, sourced from the Iraí, Passaúna, Piraquara I, and Piraquara II reservoirs.

Sanepar's technology stack combines conventional water/sewage treatment infrastructure with a notable proprietary R&D initiative: 3D-printed gyroid biocarriers (PLA/ABS/PP polymers) deployed in Moving Bed Biofilm Reactors (MBBRs) at the Mandacaru pilot plant in Maringá, achieving 87% BOD, 87% ammonia, 97% nitrate, and 96% suspended solids removal. Customer-facing operations run through the Minha Sanepar digital ecosystem — a web portal, iOS/Android apps, WhatsApp Business channel, Gov.br SSO, SOPAGUE-integrated payment portal, Digital Bill, tariff simulator, and ombudsman (Canal Íntegro) — supported by real-time reservoir data from INFOHIDRO/SIMEPAR.

The business model is regulated and subscription-based. Tariffs are set under Brazil's incentive-based regulation (Parcel A non-manageable costs / Parcel B manageable costs), adjusted via Periodic Tariff Review, Extraordinary Tariff Review, and the Tariff Adjustment Index, with a Social Tariff for low-income customers. Revenue is diversified across residential, commercial, and industrial customers plus municipal government contracts; the Municipality of Curitiba alone represents ~22.3% of revenue. The company monetizes sewage operations through PPPs with Acciona (West Lot 1, 48 municipalities), Iguá Saneamento (West Lot 2, 28 municipalities), and Saneamento Consultoria (Central-Coastal 16 and Central-East 36 municipalities) — Sanepar retains billing and customer service while private partners handle sewage construction and operations. Strategic adjacencies include the Sanebio biosolids program, industrial water reuse via the Hub de Novos Negócios (Resolution 758/2024-CA), organic waste treatment at ETE Belém, and a 2026 MoU with UK-based Firefly to convert biosolids into sustainable aviation fuel feedstock. FY2025 revenue was BRL 7.206 billion (+5.2% YoY) with a 41.1% EBITDA margin and BRL 2.080 billion net profit (+34.6% YoY), supported by a US$2.2 billion five-year investment plan and BRL 2.6 billion 2026 CapEx targeting 100% sewage universalization by 2029.
