Entering The Rainy Season, ITDC Ensures That The Mandalika Drainage System Functions Optimally

JAKARTA - InJourney Tourism Development Corporation (ITDC), a member of the InJourney Group, ensures that drainage channels in all operational areas of the Mandalika Special Economic Zone (SEZ) function optimally in anticipation of entering the rainy season.

Cleaning drainage channels in all area operational areas is also carried out as an effort by ITDC to ensure that the water system functions optimally, reduces the risk of inundation, potential sedimentation, maintains area cleanliness, and ensures the sustainability of tourism destination supporting infrastructure.

PGS. General Manager of The Mandalika, Agus Setiawan, said that the main focus of cleaning is in the West Zone of The Mandalika SEZ, which has the longest drainage network and is the main route for water flow from the area to the final disposal point.

Agus said the normalization was carried out by cleaning channels from garbage, silting, and bushes that could potentially block the flow of water, using heavy equipment and support fleets.

Based on field monitoring, during October 2025, the volume of silt deposits and garbage rose by about 10 percent compared to the previous month.

This increase is due to increased intensity of rain and changes in land conversion in the upstream and surrounding areas, which have an impact on high sedimentation in drainage channels.

ITDC then accelerated drainage normalization at a number of priority points, involving 89 joint personnel from the gardener team, cleaning teams, operational teams, firefighters, assisted by an operational truck fleet for transportation.

"We ensure that all regional supporting infrastructure, including drainage channels, is in prime condition so that the water management function continues to run well even though rainfall increases. This step is a form of ITDC's operational readiness in minimizing the risk of puddles and supporting the application of the principle of sustainability in tourism destinations," Agus said in an official statement, Thursday, November 6.

Agus said the drainage system in the Mandalika SEZ was designed with an open pattern connected to several catchment areas (water catchment areas) and the final disposal route in the southern part of the area.

"This design allows rainwater flow to be channeled efficiently to the disposal point, as well as serves as a surface runoff control system," he explained.

To maintain system performance, ITDC routinely maintains and cleans channels to ensure water capacity remains stable and prevent sedimentation that can hinder flow.

"Cleaning drainage is the implementation of the ITDC Environmental Management program which is carried out continuously," he said.

This program includes various initiatives such as reforestation of the region, integrated waste management, and control of erosion in the area around the tourism area. This is in line with information from the Meteorology, Climatology and Geophysics Agency (BMKG) which states that the West Nusa Tenggara region has entered the beginning of the rainy season from late October to early November 2025, with an intensity of intermediate rainfall in the southern region of Lombok Island.

Through environmental management measures, ITDC contributes to the achievement of the Sustainable Development Goals (SDGs), particularly in supporting the management of clean water and sustainable sanitation (SDGs 6), development of resilient areas for climate change (SDGs 11), and mitigation of environmental impact (SDGs 13).

Kata Agus, pendekatan ini menegaskan peran ITDC sebagai sustainable tourism developer yang konsisten mengintegrasikan aspek lingkungan ke dalam setiap kebijakan operasional kawasan.

Agus said, this approach confirms the role of ITDC as a sustainable tourism developer that consistently integrates environmental aspects into every regional operational policy.

"Through this effort, ITDC is committed to keeping the Mandalika SEZ not only a leading tourist destination, but also an example of a sustainable tourism area that is adaptive to environmental change. We want to ensure that every operational step in this area is always in line with the principles of ecosystem sustainability around it," concluded Agus.
