In 2023, Air Selangor recorded RM2.82 billion in total revenue, an increase of 15.1% from RM2.45 billion recorded in the previous year. This increase is the result of various operational incomes of Air Selangor. Air Selangor will continue to invest in the long-term management and administration of water supply for its 9.3 million users in Selangor, Kuala Lumpur, and Putrajaya, where appropriate and holistic tariff adjustments can ensure continuous service quality improvement.


Air Selangor incurred CAPEX expenditure of RM0.56 billion billion in 2023, compared to RM2.68 billion in 2022, most of which was spent on the Rasau Water Supply Scheme Stage 1 project in 2022 (RM1.97 billion).

These Sustainability Sukuk are allocated for water supply projects, sustainable water management, and renewable energy initiatives. This includes the development of new water treatment facilities, maintenance of existing facilities, pipe replacement programmes, and the Renewable Energy for Water (RENEW) project.


Additionally, the NRW Reduction Becoming Mainstream programme launched in July 2023 reflects our proactive step in encouraging the involvement of consumers and employees of Air Selangor to reduce the rate of Non-Revenue Water (NRW). Through the Air Selangor app, consumers can now report pipe leaks, broken pipes, meter leaks, or illegal pipe installation easily and directly assist Air Selangor in our commitment to ensure sustainable and efficient water distribution management.


Air Selangor remains committed in driving all efforts to realising its aspirations to become the leading water services provider in Asia by 2030.
