Detailed Standards Coverage

EN 12255-2:2026 – Storm Water Management in Wastewater Treatment Plants

Wastewater Treatment Plants – Part 2: Storm Water Management Systems

This European standard focuses on the design, implementation, and operation of storm water management systems within wastewater treatment plants. It clarifies requirements for the separation, storage, treatment, discharge, and return of storm water, ensuring systems are fit for purpose during both typical and extreme rainfall events. Coverage explicitly excludes storm water management for sewer networks, instead referencing their respective standards (EN 752, EN 16933).

Key requirements laid out in EN 12255-2:2026 include:

• Flow management systems: Separation of storm inflows, with explicit sizing and design criteria for storm tanks, control of return flows, and appropriate cleaning systems.
• Instrumentation and automation: Mandates for measurement, monitoring, and automation to ensure reliable control of flows during storm events.
• Storage and partial treatment: Storm tanks must provide sufficient volume for short-term events, prevent solids discharge via sedimentation/screening, and enable safe return of stored water for full treatment.

Who must comply? This standard is binding for wastewater engineering professionals, municipal authorities, treatment plant designers, and facility operators overseeing plants with inadequate upstream storm management.

Practical implications:

• Improved resilience and compliance with European regulatory targets for effluent quality and overflow control.
• Reduced environmental impact by preventing uncontrolled storm water discharges.
• Alignment with systems integration and digital monitoring trends.

Key highlights:

• Comprehensive requirements for storm tank sizing, design, and cleaning
• Integration with broader treatment plant automation and monitoring networks
• Reinforced best practices for overflow prevention and partial treatment

• Reporting and traceability: Structured templates for sampling site documentation, sample identity, and operational conditions.

Target audience: Water quality laboratories, environmental monitoring agencies, biodiversity researchers, and regulatory bodies requiring evidence-based aquatic ecosystem assessments.

Practical implications:

• Enhanced reliability and comparability of eDNA results across laboratories and jurisdictions.
• Lower risk of false negatives/positives through robust contamination avoidance.
• Streamlined compliance with regional biodiversity directives (e.g., EU Water Framework Directive).

Key highlights:

• End-to-end protocols for eDNA sample collection and preservation
• Emphasis on contamination avoidance and procedural reporting
• Applicable to freshwater and marine sampling, but excludes biofilms or sediments
