Urban Infrastructure Projects: Jakarta, Indonesia

Decentralized waste water management

In 2017, only 55.5% of Jakarta city residents had access to clean water. Only 26% of the population has access to clean, piped water, only 4% of Jakarta’s population has access to the sewerage system and, 470,000 households (14% of the city) still practice open defecation. The limited coverage of piped water means that 74% of households rely on ground water or river water which is frequently polluted. To improve the sewerage service, Jakarta has prepared a waste water master plan which, if fully implemented, will only ensure that 65% of Jakarta’s residents will be covered by the piped sewerage system by 2022.

Technologies have now evolved to a point where small odorless wastewater and recycled water treatment plants, based on biological processes, can be integrated into the dense urban fabric of cities. This kind of technological innovation has the potential to deliver multiple-benefits at the community scale (improved sanitation and access to clean water) and have wider benefits for Jakarta city as a whole (reduced health costs, improved sanitation infrastructure, reduced GHGs).

Jakarta City Government is investigating the management and operation of decentralized settlement scale wastewater treatment plants on government owned public space across Jakarta. This approach is an opportunity to meet the needs of the 8.5 million people who will still be without access to the sewerage system in 2020.

Investment/Partnership Opportunity:

An initial scoping study has identified potential pilot sites across Jakarta and reviewing opportunities, constraints and relevant technologies for each location.

Jakarta DKI expects to pilot one or two pilot sites in 2018. Following proposed pilots in 2018, there will be an opportunity to review, improve and scale up this approach across the city.
