Managing the Welang Floods in East Java

Partners for Water recently sat down with Fauzy Nasruddin, the Secretary at the Water Resources Agency of East Java Province (Indonesia) and spoke about the collaboration with the Netherlands on managing the floods in the Welang river basin in East Java.

Fauzy Nasruddin has significant expertise and experience in water management, and visited Delft in September to accompany his staff members on a short course at the Institute for Water Education (IHE) which also allowed him to join his wife’s graduation. Just like him, she studied at the Institute for Water Education (IHE).

Long-standing collaboration

For the last decades, Fauzy Nasruddin has been deeply involved in collaborative water management projects, including those funded by Partners for Water, predominantly addressing issues like flooding, drought, and water pollution in East Java. The challenges of having too much, too little, or too polluted water should eventually be replaced by the 3 Rs of sustainable water management: Recharge, Retention, and Reuse.

The partnership with the Dutch government formally began in 2020, but its roots date back to 2015. That year, the former Dutch minister Stef Blok came to East Java to visit the grave of his grandfather, an engineer who built a dam in the region during the colonial period. This dam still functions today, symbolizing the historical connection and shared expertise between the two countries.

Early dialogue and exploration

In 2018, a delegation from East Java, including Fauzy Nasruddin himself, visited the Netherlands. They travelled to Zeeland and were invited to the University of Applied Sciences to explore potential areas of collaboration and discuss cases of mutual interest, including flood and water quality issues in East Java. In 2020, the collaboration was strengthened during a royal visit to Indonesia.

The Minister of Infrastructure and Water Management visited Surabaya, where Nasruddin’s office is located. She decided that the Welang River could be a pilot project for further cooperation in water management. The river basin is experiencing great problems with flooding and has been the subject of various water management and flood control projects, including collaborative efforts between Indonesia and the Netherlands.

The Welang river’s challenges

The Welang River floods between eight and ten times a year during the rainy season, which lasts from December to March. These floods have significant impacts on local communities, especially the poorer populations who are more vulnerable to natural disasters. While past infrastructure projects, such as building levees and reinforcing riverbanks with stones and concrete (grey infrastructure), have been undertaken, these solutions proved temporary. The floods returned, indicating a need for more sustainable and integrated approaches.

A new approach: the Welang River Master Plan

As part of the collaboration with the Netherlands, a Master Plan for the Welang River has been developed, followed by several pilot projects that focus on integrated and participatory water management, design and implementation. The goal is to manage floods by slowing down and absorbing water in the watershed rather than simply diverting it as quickly as possible. In upstream areas, solutions that use local materials and labour are being found, so they are not only cost-effective but also sustainable and scalable, as local communities can maintain and replicate them, Nasruddin says.

“Early results indicate that these methods are effective at a pilot scale, but scaling them up across more locations, midstream and downstream, is still work in progress,” he adds. The collaboration in Welang is a showcase of integrated planning and implementation, involving a diverse set of local stakeholders. In the midstream and downstream locations, the collaboration is taking a participatory design approach to jointly identify and agree upon interventions that improve water management in critical flooding areas.

A concrete example of such a pilot project is the construction of simple water barriers in the upstream part of the Welang River. These structures, made of bamboo, wood, and local stones, retain water and reduce sedimentation. While some early attempts were unsuccessful – some bamboo structures collapsed during heavy floods – the project has provided valuable insights. It underscores the importance of designing structures that are strong enough to withstand extreme weather conditions while fitting the local context and capabilities.

Challenges

One of the biggest challenges Nasruddin mentions is the complexity of the administrative and political landscape in Indonesia. Political changes can lead to shifts in priorities and budgets, hindering the continuity of long-term projects. He compares this to the situation in the Netherlands, where a Delta Act and a fixed Delta Budget ensure consistent funding and planning, regardless of political changes. He sees the lack of a similar legal framework in Indonesia as an obstacle to sustainable water management initiatives.

Another issue is the involvement of multiple stakeholders with different interests. In the upstream area of the Welang River, for example, forestry agencies, water companies, environmental organizations, and local communities are all active. Each of these parties has its own priorities, making it difficult to arrive at a joint action plan. Nasruddin stresses the importance of stakeholder engagement and co-creation, where all involved parties are included in the process from the start. This not only promotes collaboration but also ensures that solutions better fit the needs and context of the local community.

The economic aspects are also a challenge. Investments in water infrastructure, especially in flood control and upstream conservation, are often seen as less profitable compared to projects like toll roads or commercial developments. This makes it harder to secure funding for crucial water management projects that may not provide immediate financial returns but are essential for the sustainability and safety of communities.

Personal motivation

Nasruddin’s personal motivation stems from his passion for water management and the realization that well-managed water can improve lives and make communities more resilient. He sees water as a common good that, when effectively managed, can have tremendous positive effects on society. His experience in the Netherlands has broadened his perspective, particularly in understanding the importance of process management and stakeholder involvement alongside technical solutions

Future hopes

In the future, he hopes that Indonesia can develop a legal framework similar to the Dutch Delta Act, enabling long-term and stable investments in water management. However, he acknowledges that this is a complex process, given the political dynamics and the diverse interests of stakeholders. Nonetheless, he remains committed to improvement and innovation in water management, with the ultimate goal of improving the quality of life for the people of East Java and making the region more resilient to the challenges of climate change and population growth.​
