Certificate in Greywater Management Systems

Greywater Management Systems provides learners with a comprehensive understanding of the principles, design considerations, installation, operation, and maintenance of systems used to collect, treat, reuse, and manage greywater. The programme covers greywater sources, collection systems, segregation from blackwater, filtration and treatment principles, storage, distribution, reuse applications, water quality, health and safety, maintenance, and environmental considerations. Learners will explore how appropriately designed greywater systems can support water conservation and reduce demand on potable water supplies. Emphasis is placed on safe system management, efficient operation, responsible reuse, and compliance with applicable technical and environmental requirements.
