Area of Constructed Wetlands Required in 2030

The Green Open Space in Jakarta 2030 plan targeted at 30% of the Province area.

It's 196km²

The Required Wetlands Area is 13.83km²

It only account for 7% to GOS 2030.

There is great potential for this Natural-based approach to treat wastewater in 2030 Jakarta!!!

Located in west Jakarta, Kampung Kedaung Kali Angke suffers from serious water pollution and scarcity of clean water. According to the investigation, the current stormwater system is a “one-way flow” system where stormwater runoff goes straight into canals. There is no system to clean, to harvest and to store for heavy storms, which results in water pollution and scarcity of clean water.

This project aims to create a new ecological and sustainable stormwater “circular flow” system to filter, harvest and recycle rainwater in Kendaung Kali Angke. The proposal selects three open sites of different sizes focusing at the south-western corner of Kampung Kedaung Kali Angke for design interventions. The three sites are chosen from three perspectives: public, community and household, with different new stormwater treatment systems.

Site 1: Public habitat

(Total open space area: 9ha; Water storage capacity: 48000m3)

A new wetland water treatment system is established in this area to increase diversity, improve water quality and provide wildlife habitats. The treatment wetland will perform its ecological function differently in each season. For dry season, wetlands store clean water filtered by complex systems for agricultural irrigation. For rainy season, wetlands provide space for stormwater runoff to gather and mitigate the effects of pollution.

Site 2: Community mixed-use

(Total open space area: 2ha; Water storage capacity: 6750m3)

The rainwater collected from the roof of the factories is filtered through a complex stormwater treatment system to obtain clean water. Clean water is then pumped to the households and factories. In the meanwhile, stormwater runoff from the roads will be collected and diverted to a newly designed terraced raingarden, with the treated water being harvested for storage, irrigation and community-use.

Site 3: Local household

(Total open space area: 0.3ha; Water storage capacity: 840m3)

A model of shared water shop is proposed in this site. The rainwater is collected from individual households through the water pipe, and it is filtered and treated in the shared water shop to access clean water for household-use. The small raingarden is used to clean and filter stormwater runoff from roads naturally.

Additionally, a green corridor is built to connect the three sites and the surrounding communities so that people can interact with nature and enjoy recreation spaces. Depending on the size of the sites, the project can be applied to other parts of Kendaung Kali Angke as a model to address the issue of water pollution and provide clean water.
