Jakarta water supply provision strategy based on supply and demand analysis

Abstract

Robust water service delivery systems require an understanding of resource dynamics as a basis for planning sustainable solutions for Jakarta, the capital with challenging water service provision performance. A significant gap needed to be closed with a service coverage of 64.06% and non-revenue for water at 45.06%. However, there is no detailed information on Jakarta's water supply and demand, which is essential to understand the resources situation. This study estimates Jakarta's total water supply and demand for 5 years. Furthermore, we analyze the natural and socio-economic factors shaping the current supply and demand using thematic analysis based on the DPSIR (Driver, Pressure, Status, Impact, and Response) framework. This paper contributes to two building blocks in the system strengthening approach to water and sanitation, i.e., (1) the sector policy strategy and (2) planning, monitoring, and review. Key drivers, pressures, status, impacts, and responses were critical to informing the system-wide understanding of the problem and suggesting evidence-informed explanations for a better water supply provision strategy in Jakarta. HIGHLIGHTS Jakarta does not have a thorough supply and demand analysis available for the public.; DPSIR (Driver, Pressure, Status, Impact, and Response) analysis to show the ways in which water and society are interlinked.;
