Malaysia Amends Regulations Concerning Sewerage Charges

In Malaysia, the Water Services Industry (Sewerage Services Charges) Regulations 2022 were promulgated on September 20, 2022. These regulations specify the charges for sewerage for each sector. The regulations shall come into force on October 1, 2022, and the existing Sewerage Services (Charges) Regulations 1994 and the 2018 Order partially amending them will become invalid.


The table below shows the scope of the regulations and the sewerage charges.

  • Domestic premises (First Schedule)
  • Commercial premises (Second Schedule)
  • Government premises (Third Schedule)
  • Industrial premises (Fourth Schedule)


Of these, the charges for industrial premises are shown below. The amount to be paid depends on the number of workers.

Category Charge per worker (RM/per month)
Connected services 2.50
Desludging services 2.00


Desludging services are implemented every 2 or 3 years for each premises based on the Water Services Industry (Desludging Services) Regulations 2021. However, companies who wish to implement additional desludging will need to pay RM192 per case as stipulated in Schedule 6 of the regulations. The Water Services Industry (Desludging Services) Regulations 2021 require sewage service providers such as Indah Water Konsortium Sdn Bhd (IWK), the national sewerage company, to periodically perform desludging work at premises that own septic tanks.


When selling or transferring a premises, the sewerage user must pay the above sewerage charges unless they notify the sewerage service provider in advance.
