The sanitation sector in Brazil is undergoing a transformative phase, driven by ambitious government policies, private-sector participation, and a surge in infrastructure investments. For companies like Accionia, this represents a golden opportunity to capitalize on a high-growth emerging market. With Brazil's sanitation market projected to mobilize over R$95 billion in investments between 2025 and 2026, the stage is set for firms with long-term strategic vision to thrive, according to a Valor report.

A Market on the Brink of Transformation

Brazil's sanitation sector is being reshaped by the 2020 Sanitation Legal Framework, which mandates universal access to clean water for 99% of the population and sewage treatment for 90% by 2033. This policy has unlocked a pipeline of public-private partnerships (PPPs) and concessions, with 26 sanitation assets expected to go to auction in 2025 alone. These projects, including the Pará water and sewage concession (R$18.5 billion) and Pernambuco's R$18.2 billion initiative, are part of a broader R$70 billion investment wave in 2025.

Private-sector involvement has surged, rising from 15.7% in 2023 to 30% in 2024, with projections of 44% by year-end 2025. This growth is underpinned by predictable revenue streams, long-term contracts, and the sector's alignment with global sustainability goals. For instance, the cleaning and hygiene products market is forecast to grow at a 6.1% CAGR from 2025 to 2030, while water treatment chemicals are expected to expand at 5.2% annually, according to Grand View Research.

Accionia's Strategic Play in Brazil

Accionia has positioned itself as a key player in Brazil's sanitation revolution through a €324 million PPP in Paraná state, covering 48 municipalities. This 24-year contract, awarded by Sanepar, involves constructing and operating sewage networks, pumping stations, and wastewater treatment plants. The project aims to expand sanitation coverage from 25% to 100% by 2033 in the West microregion, benefiting over 323,800 people, in an ACCIONA announcement.

The company's approach emphasizes technological innovation and sustainability. Advanced tools like digital twins, IoT sensors, and predictive maintenance are deployed to optimize operations, while circular economy principles-such as sludge valorization and biogas generation-enhance resource efficiency. These strategies not only reduce costs but also align with global ESG (Environmental, Social, and Governance) standards, making Accionia's projects attractive to impact-focused investors.

Financial Implications and Long-Term Earnings Potential

While specific profitability metrics for Accionia's Brazil sanitation division in 2023–2025 remain undisclosed, the company's Infrastructure division reported €4.01 billion in revenue and €352 million in EBITDA in the first half of 2025, per ACCIONA results. This growth, coupled with the long-term nature of sanitation contracts (typically 20–30 years), suggests robust cash flow visibility.

The Paraná project, for example, spans 24 years, ensuring stable returns over a period when Brazil's sanitation market is expected to grow exponentially. With Abcon Sindcon forecasting R$95 billion in investments from 2025 to 2026, and the BNDES (Brazilian Development Bank) structuring additional projects for 2026, Accionia's foothold in this market is well-timed.

Risks and Considerations

Despite the optimism, challenges persist. Regulatory changes, inflationary pressures, and delays in project execution could impact returns. However, Accionia's experience in managing large-scale infrastructure projects-coupled with Brazil's legal certainty under the 2020 framework-mitigates many of these risks.

Include a line indicating the CAGR of the water treatment chemicals market (5.2%) and the cleaning/hygiene products market (6.1%) during the same period.

Conclusion

Accionia's strategic expansion in Brazil's sanitation sector is a masterclass in aligning with macroeconomic trends. By leveraging long-term PPPs, technological innovation, and sustainability, the company is well-positioned to capture a significant share of a market set to grow by over R$95 billion in the next two years. For investors, this represents a compelling opportunity to participate in a sector that is not only financially rewarding but also socially transformative.
