SYNOPSIS

Over the past two (2) decades, Malaysia has seen tremendous improvements in sanitation provisions to secure public health and protect the environmental resources. To date basic sanitation coverage for Malaysia is more than 95%. This progress was achieved primarily as a result of the Government’s decision in 1993 to federalize and private sewerage services. Since then, Malaysia’s sewerage system and industry had evolved and transformed to provide efficient and effective delivery of sewerage services to the public. Sewerage services in Malaysia is largely provided by Indah Water Konsortium Sdn Bhd (IWK) which is entrusted to develop and maintain a modern and efficient sewerage system in Malaysia. IWK provides services to more than 23.5 million population in 87 Local Authority areas in Peninsular Malaysia, including WP Labuan. IWK’s sewerage services covers the operation and maintenance of over 6609 public sewage treatment plants and more than 18,743 km of sewerage network.

This paper intends to share experiences of IWK, in managing sewer system nationwide and also challenges faced by IWK, in its effort to improve health, water resources and environment, including escalating costs, aging infrastructure, and increasingly stringent regulatory requirements. The extensive coverage of sewer network comes with its own challenges and not limited to the wide range in pipe size, type, and age and the large length of sewer to be operated and maintained. This paper will also discuss open cut method versus trenchless method with various technology and experiences by IWK. The extent in use of trenchless technologies for the last few years in Malaysia will also be highlighted. With new innovation and automation, repairing and rehabilitation method of sewer network has been changed to suit rapid developments especially in urban area. These changes is required to enhance the operation and maintenance of sewer systems that meet the nation’s needs for sustainable sewerage development
