The Kaiduan Dam Project Aims to Secure Water Supply for Five Districts Until 2050

The Kaiduan dam construction, a key component of the third phase of the Kota Kinabalu water supply scheme, is projected to fulfil the clean water requirements for five districts until the year 2050. This substantial infrastructure project, first proposed in 2008 and valued at RM2.8 billion, is designed to address the growing demand for water in Kota Kinabalu, Penampang, Putatan, Papar, and Tuaran. The dam's capacity is intended to augment the current water supply, which is forecast to become insufficient in the near future.
Addressing Increasing Water Demand

The need for the Kaiduan dam is underscored by projected increases in both population and consumption. In Kota Kinabalu and its surrounding areas, the population is anticipated to rise to 1.2 million by 2020, a significant jump from the current 878,000. Concurrently, global trends indicate that water consumption in developing countries could increase by 50 percent by 2025 due to changing weather patterns and climate shifts. This dual pressure of population growth and increased per capita usage necessitates a more robust water infrastructure.
Overcoming Existing Supply Limitations

Current water supply infrastructure in the affected regions is nearing its capacity limit. The existing capacity stands at 439.5 million litres per day, a volume that is estimated to be adequate only until 2022. The Kaiduan dam is therefore a critical intervention to prevent future water shortages and ensure a continuous supply for the projected population growth and consumption levels beyond the immediate limitations of the current system.
Long-Term Water Security for Multiple Districts

The strategic objective of the Kaiduan dam is to provide a sustainable water source for Kota Kinabalu, Tuaran, Penampang, Putatan, and Papar districts for an extended period. The planning indicates that the dam's output will be crucial for meeting the water needs of these areas up to 2050. This long-term provision aims to support the continued development and well-being of the region by securing a fundamental resource.
Acknowledging Environmental Considerations

While the dam project is vital for water security, its implementation has also brought environmental concerns to the forefront. Specifically, there are apprehensions regarding the potential impact on the Sungai Papar ecosystem. This includes considerations for the local tagal system, a community-based fisheries management system practised by residents along the river, which could be affected by the dam's construction and operation.
