CSRD Water: Meet regulations and exceed sustainability performance

At Paques, we believe protecting the planet is a shared responsibility. By helping companies align with CSRD and drive down water- and carbon-related impacts, we turn compliance into opportunity—for your business and the environment.” Our high-rate biological wastewater treatment solutions help companies:

	Ensure compliance with ESRS E3 & ESRS E2 – Our solutions align with the CSRD and support key disclosures on water use, pollution risks, and efficiency.
	Advance sustainability goals – Directly contribute to SDG6 (Clean Water), SDG7 (Clean Energy), and SDG9 (Sustainable Industry) by optimizing wastewater treatment.
	Enhance CSRD water metrics – Reduce water use, cut carbon emissions, and recover valuable resources from wastewater. This strengthens your reputation, so you can stay or become a preferred supply chain partner.
	Improve financial resilience – Prepare for increased loading rates, reduce operational costs and ensure long-term environmental compliance. Read more.

CSRD requires companies to report according to the European Sustainability Reporting Standards (ESRS), particularly:

1. ESRS E3 – Water and Marine Resources

• Total water withdrawals and consumption, especially in water-stressed regions.
• Water reuse and efficiency measures to reduce reliance on freshwater sources.
• Wastewater discharge impacts, including pollutant levels and treatment efficiency.
• Policies and investments in sustainable water management.
• Financial risks and mitigation strategies related to water usage and regulation.

2. ESRS E2 – Pollution of Water

• Disclosure of hazardous substances, pollutants, and contamination risks in wastewater discharge.
• Measures taken to prevent, reduce, or mitigate pollution from industrial activities.
• Alignment with Zero Pollution goals of the EU Green Deal.
• Compliance with REACH regulations for chemical safety.

To meet CSRD compliance and enhance sustainability performance, organizations – including manufacturers and public authorities – should take the following steps:

• Optimize wastewater treatmentto decrease pollution and improve water quality and recovery. Our expertise in high-efficiency treatment can help streamline compliance book a free consultation.
• Deploy biological treatment technologies to lower carbon emissions and minimize sludge production.
• Reduce water intake by integrating circular water management and reuse strategies
• Implement real-time water monitoring for accurate tracking of water use, pollution metrics, and efficiency improvements.
• Quantify financial risks associated with water resources and integrate them into financial disclosures.

• Conduct a double materiality assessment to determine both financial and environmental impacts of water management practices.

By proactively improving wastewater treatment infrastructure and aligning with CSRD reporting standards, organizations can reduce regulatory risks, enhance sustainability performance, and create long-term financial value.

• Operational savings – Lower water purchase and discharge fees.
• Compliance risk reduction – Avoid regulatory fines and penalties.
• New revenue streams – Generate value from recovered resources like phosphate, sulfide and metals and biogas.
• Increased competitiveness – Meet procurement sustainability requirements from multinational buyers.

CSRD (water) metrics are increasingly used to evaluate suppliers' environmental impact. This means you can show your (potential) customers you are a true sustainability leader via CSRD (water) reporting with tangible improvements in water use, carbon footprint, and resource recovery. Just apply the expert guidance on sustainable water management from the global leader in water treatment biotechnology.

The EU Water Reuse Regulation (EU 2020/741) establishes minimum water quality standards for the safe reuse of treated wastewater. Companies should:

• Align wastewater treatment strategies with regulatory water quality and monitoring requirements.
• Implement risk assessment frameworks to ensure compliance with water reuse projects.
• Demonstrate how water reuse contributes to sustainability goals and financial stability.

• Apply modular biological treatment solutions for compliance and efficiency improvements, such as BIOPAQ^® ICX, BIOPAQ^® UASBplus and BIOPAQ^® RISE
• Data-driven process optimization for real-time CSRD reporting enhancements.
• Integration of water reuse strategies to minimize environmental impact and meet CSRD standards.
• Investment in pollution control technologies, such as ANAMMOX®, PHOSPAQ™, or SULFATEQ™ to ensure compliance with ESRS E2 regulations.
