The Indonesian Capital City Authority (OIKN) is building 24 water bodies in the form of reservoirs and water retention ponds with a total capacity of 2 million cubic meters, to ensure a sustainable water supply in the IKN and the surrounding areas.
"The construction of 24 water bodies with a capacity of 2 million cubic meters is to add to the 2 million cubic meters that we already have from the 30 existing reservoirs," said Head of OIKN Basuki Hadimuljono in Nusantara, East Kalimantan, on Friday.
He said that the construction of the reservoir and retention pond has a strategic function in supporting the Zero Delta Q or Sponge City concept promoted by Nusantara.
This infrastructure is designed to retain, absorb and control surface water flow, the hope is to reduce the risk of excessive water runoff, while also maintaining the hydrological balance of the area.
Through this mechanism, he continued, the development of this water body also supports a sustainable water conservation system and increases environmental resilience to climate change.
"In addition to their conservation function, the presence of all these water bodies also adds value to the aesthetics and quality of the space in the IKN's Central Government Core Area (KIPP)," he said.
Reservoirs and retention ponds play a role in beautifying the city landscape, creating green open spaces that enrich the character of the archipelago as a green, shady capital city oriented towards harmony between modern development and natural sustainability.
It is also believed that these spaces can become locations for social interaction, public recreation, and communal spaces that support the quality of life of the community.
"Another benefit is that it provides a secondary source of raw water that can be used for garden watering, incidental needs such as firefighting, and lowering the air temperature in the surrounding area," he said.
Including the function of controlling flooding on a micro and macro scale, so that the existence of reservoirs and retention ponds is an important part in building a safe, resilient, adaptive and sustainable basic infrastructure of the archipelago.
