Overview
ISO 22524:2020 - "Pilot plan for industrial wastewater treatment facilities in the objective of water reuse" provides principles and guidelines for planning, executing and reporting pilot studies of industrial wastewater treatment technologies intended to enable water reuse. The standard applies to a wide range of industrial water treatment systems but explicitly excludes laboratory R&D and downstream reuse operations (for example irrigation). ISO 22524:2020 guides the full pilot lifecycle from goal setting and design through commissioning, operation, sampling and decommissioning.
Key topics
The standard addresses practical, project-level requirements and management topics, including:
- Pilot plan lifecycle: phases such as statement of goals, pilot study programme, plant design and construction, commissioning, operation, shutdown and decommissioning.
- Programme and project management: oversight committee, pilot study team roles, leadership, schedule planning, risk management and quality management system considerations.
- Design and construction: Basis of Design (BoD), conceptual and detailed engineering, contracting, acceptance testing and handover.
- Operational framework: procedure manuals, operation & maintenance protocols, sampling and measurement planning, analyzers, sampling frequency and validation.
- Commissioning and testing: staged commissioning, ‘dry’ and ‘wet’ runs, acceptance criteria.
- Performance regimes: guidance for reduced-loading (best case), normal-loading (typical) and stressed-loading (worst case) pilot operations.
- Data and reporting: statistical tools, sample collection plans, study summary and reporting, success/failure criteria and post-pilot recommendations.
Practical applications
ISO 22524:2020 is designed for organizations planning to evaluate full-scale or pre-commercial industrial wastewater treatment solutions for water reuse. Typical users include:
- Process and environmental engineers running pilot plants to validate treatment trains for reuse quality objectives.
- Water reuse project managers and plant owners coordinating pilot programmes, contractors and technical teams.
- Technology providers and integrators demonstrating treatment performance under site-specific conditions.
- Regulators and compliance teams assessing pilot study robustness, sampling protocols and reporting.
Benefits include clearer pilot objectives, structured commissioning and sampling procedures, risk reduction, and higher confidence in scalability to full-scale reuse systems.
Related standards
ISO 22524:2020 sits within ISO/TC 282 (Water reuse) work. Complementary standards and management frameworks often used with pilot studies include ISO 9001 (quality management) and ISO 14001 (environmental management), as well as sector-specific water reuse guidance.
