WATER is one of Sabah’s most precious natural assets. It sustains daily life, supports agriculture and industry, generates energy, protects communities from floods, and preserves the rivers and ecosystems that define Sabah’s natural heritage.
How water is managed therefore affects not only public safety and quality of life, but also economic growth, social stability, and environmental sustainability.
Recognising this, the Sabah Water Resources Master Plan (SWRMP) was developed in 1994 as a long-term and integrated framework for managing the state’s water resources.
Although the plan was prepared more than three decades ago, its relevance today is striking. Many of the challenges Sabah now faces such as flooding, water supply reliability, growing demand, and climate uncertainty which were already anticipated in the plan.
As Sabah advances under the Sabah Maju Jaya (SMJ) 2.0 development agenda, revisiting and strengthening the SWRMP is both timely and necessary.
At the heart of the SWRMP is the principle of integrated water resources management. This approach recognises that rivers, catchments, water supply, flood control, energy generation, and environmental protection are deeply interconnected.
Decisions made in one sector inevitably affect others. The plan therefore emphasised coordinated planning across agencies and balanced development that considers long-term impacts. This philosophy aligns closely with SMJ 2.0’s focus on resilience, sustainability, inclusiveness, and long-term value.
Flooding remains one of Sabah’s most visible and disruptive water-related challenges. Seasonal monsoon rains, combined with river basin characteristics and rapid development in some areas, continue to expose communities, infrastructure, and economic activities to flood risks.
The SWRMP 1994 proposed a comprehensive approach to flood management, including flood retention dams and reservoirs, improvements to river capacity and drainage systems, and better catchment and land-use planning to reduce risks over time.
These strategies remain highly relevant today. What has changed is the availability of technology to strengthen them. Real-time rainfall and river level monitoring, digital flood forecasting, and early warning systems can now provide earlier alerts and more accurate information.
When supported by clear emergency procedures and strong coordination among agencies, these tools can significantly reduce damage, disruption, and loss. Under SMJ 2.0, flood resilience is not just about responding to disasters, but about building confidence, safety, and stability for communities and investors.
Water security is equally important for Sabah’s future. As population growth, urban expansion, and economic activities continue, demand for clean and reliable water supply is increasing.
The SWRMP 1994 recognised this trend early and proposed strategic reservoirs to support supply during dry periods, integrated management of surface water and groundwater, and improvements in water treatment and distribution efficiency.
These measures remain central to SMJ 2.0’s emphasis on strengthening basic infrastructure and improving public services. Reliable water supply improves quality of life, supports economic productivity, and reduces vulnerability during droughts. It is also important that water planning addresses both urban and rural needs.
Rural communities, in particular, benefit from decentralised solutions such as small-scale reservoirs, rainwater harvesting, and community-based water systems, which improve resilience while supporting inclusive development.
Agriculture continues to play a vital role in Sabah’s economy and rural livelihoods. Reliable water supply is essential for crop productivity, income stability, and food security.
The SWRMP 1994 highlighted the importance of irrigation development and efficient water use, especially in areas with seasonal rainfall variation. Improving irrigation efficiency and water storage helps farmers achieve better yields while using water more sustainably.
Today, modern agricultural water solutions offer new opportunities. Solar-powered pumps, smart irrigation systems that respond to soil moisture, and small community reservoirs can help farmers cope with dry spells, reduce costs, and increase productivity.
These approaches support SMJ 2.0’s goals of rural upliftment, agricultural modernisation, and balanced regional development.
The SWRMP 1994 also recognised Sabah’s strong potential for hydropower. With its extensive river systems and suitable topography, the state has the capacity to generate renewable energy while supporting other water-related functions.
Well-planned hydropower projects can generate clean electricity, provide water storage, regulate river flows, and reduce downstream flood risks.
Under SMJ 2.0, multi-purpose water infrastructure can contribute to energy security and Sabah’s transition towards cleaner energy sources. Reduced reliance on fossil fuels supports long-term sustainability and aligns with national and global climate commitments.
At the same time, hydropower reservoirs can support eco-tourism, inland fisheries, and recreation, provided environmental protection and community interests are respected.
Strong governance and coordination are critical to effective water management. The SWRMP 1994 emphasised coordination among agencies, recognising that water-related responsibilities are often spread across multiple institutions.
SMJ 2.0 offers an opportunity to strengthen this integrated approach through river basin-based planning, shared data systems, and clearer roles and responsibilities. Digital tools can improve transparency, support evidence-based decisions, and enhance public trust.
Environmental protection and community well-being must remain central to water development. The SWRMP stressed the need to balance development with environmental stewardship, recognising that healthy rivers and ecosystems are essential for long-term sustainability.
Meaningful engagement with local and indigenous communities is equally important to ensure projects are inclusive, culturally respectful, and socially accepted.
In conclusion, the Sabah Water Resources Master Plan 1994 remains a valuable and forward-looking framework. Far from being outdated, it provides a strong foundation for addressing today’s challenges and future uncertainties.
By updating the plan with current data, modern technology, and stronger governance – while staying true to its integrated vision – Sabah can turn its water resources into a pillar of resilience, opportunity, and shared prosperity, in line with the Sabah Maju Jaya 2.0 vision.
