... is Malaysia’s national sewerage company, owned by the Minister of Finance Incorporated to develop and maintain a modern and efficient sewerage system for all Malaysians.

In 1994, the Federal Government awarded the company the concession for nationwide sewerage services which prior to that, was under the responsibility of local authorities.

Since then, Indah Water has taken over the sewerage services from local authorities in all areas except Sabah and Sarawak.

A modern and efficient sewerage system is vital for the country so as to ensure that wastewater is treated before being discharged into our rivers. This will help preserve the country’s water resources, protect public health and provide a cleaner and safer environment.


In June 2000, as testimony of the Government's seriousness in ensuring that a proper and efficient sewerage system will be successfully put in place and maintained, the Government, through the Minister of Finance Incorporated, took over the entire equity in Indah Water from its previous private owners.

Indah Water is now well-positioned to undertake the vital task of ensuring that Malaysians today and in the future will be able to enjoy a clean and healthy environment through a proper and well-maintained sewerage system.
