Indah Water Konsortium (IWK) Sdn Bhd advocates the need to enhance knowledge and skill of its staff and other workers and practitioners in the sewage sector to be effective and efficient in planning, operations and maintenance of its sewerage assets. For this, IWK’s ASTRICE was established at the Sg. Besi Regional Sewage Treatment Works, Bukit Jalil in February 2006. The training centre is a dedicated location for technical training on sewerage systems that focuses on theory and practical for IWK staff and the wider public (both local and international).

IWK's strategy on developing knowledge, skills and competencies to meet business and industry demands. Hence, its training and development program focuses on capacity building in areas of customer relations, health and safety, fundamentals of sewerage systems to new technology, processes and skills.
