Demand and Supply Analysis as a Basis for Jakarta Water Provision Planning

Abstract

Water provision is a necessity to reduce the risk of coronavirus contamination. Delivering water and sanitation services is now more critical than ever; the hygiene requirements increased water need. It is expected to grow even after the pandemic as a healthier habit that will become a routine for most of the population. In addition, economic activity is predicted to expand once the pandemic is under control. To safeguard sustainable water provision, it is critical for Jakarta to have comprehensive planning based on careful calculation of demand and supply. This is especially valid as climate change adds the pressures to water availability that have long been experienced by the capital, such as pollution, high reliance on groundwater, huge water supply from outside the region, lack of infrastructure, land subsidence, floods, and land-use change. This study aims to estimate the demand and supply for Jakarta’s water comprehensively, cover all water sources inside and outside the capital, and develop a strategy based on the analysis produced. The strategy includes the need to focus on reducing, reusing and recycling approaches to local water available in Jakarta.
