The Meteorology, Climatology, and Geophysics Agency (BMKG/Badan Meteorologi, Klimatologi, dan Geofisika) has announced the arrival of the rainy season. This information can be seen in the monthly bulletin at the end of November. You have experienced it in Jakarta too, right? Those heading home choose to take shelter, whilst those at music festivals willingly stand watching performances, wearing ponchos.

We all realise heavy rainfall has significant impacts on the environment, including the formation of puddles that may lead to flooding. To prevent this, several measures are taken by the Jakarta Provincial Government to ensure the safety of its residents.

 

Management of Water Flow

62 Reservoirs, Embankments, and Lakes in East Jakarta

As rainfall increases, water levels rise. Puddles in waterways such as rivers, reservoirs, embankments, and lakes need to be taken care of. East Jakarta is equipped with reservoirs, embankments, and lakes to regulate water flow through rivers or water channels. Construction of water channels is ongoing, and currently, there are 62 operational reservoirs, embankments, and lakes in East Jakarta. These water channels enhance water retention during the rainy season.

9 Excavators in the Ciliwung River

Sedimentation or mud deposition makes it hard for water to flow. Hence, the Provincial Government conducts mud dredging in water channels like the Ciliwung Riverin the Kebon Baru segment. Nine excavators are utilised for mud dredging, increasing water retention in the river and ensuring smooth channel connectivity.

Going Green

Open land needs to be organised to maintain the environment. Planting trees is one way to prevent flooding. So far, greening efforts in Jakarta include planting:

  • over 57,000 mangrove trees;

  • over 77,000 protective trees; and

  • over 4,000,000 ornamental plants.

Greening is crucial in areas like Jakarta, as planted trees absorb water from the soil, contributing to flood prevention.

Hundreds of Stationary Pump Units

Some areas in Jakarta are below sea level, making it hard for water to flow by gravity. Therefore, stationary pumps are essential infrastructure in Jakarta to redirect water and control flooding.

 

Flood prevention in Jakarta involves 549 stationary pump units at 195 locations and the construction of 799 water gates at 547 locations. Two additional pumps are also installed in Ancol, along with others in Gunung Sahari.

Dedication and Collaboration of All Jakartans

Jakarta continues to face various urban challenges. Without the participation of its residents, environmental sustainability is not possible. The Provincial Government continually urges everyone to participate in environmental conservation.

 

As a form of resident participation, the Bakti Kita untuk Jakarta event took place on 19 November 2023. Joko Agus Setyono, the Secretary of the Regional Secretariat of DKI Jakarta Province, along with assistant secretaries, heads of regional agencies, and regional-owned enterprises, gathered in the morning for a massive community service. Various layers of Jakarta's society also participated. Cleaning water channels, from front drains to canals or rivers, was done to anticipate flooding.
