Integration usage of statistical and spatial data for modeling household water needs and water access in Bandung city, Indonesia

Clean water is a basic human need. Ensuring communities achieve universal and equitable clean water access is the sixth of Sustainable Development Goals (SDGs) and National Medium-Term Development Plan (RPJMN). However, not all households already have access to piped water. There are still many households that use groundwater and other water sources to meet daily water needs. The lack of reliable water services in Bandung City will lead to excessive groundwater intake, which can lead to land subsidence problems. In 2017, achievement of new water access services was around 72% or only up slightly from 2014 which should be targeted in 2019 according to National Medium-Term Development Plan (RPJMN). Plan to meet clean water access can’t be done optimally caused there hasn’t been much development of analysis on water access in detail. This study attempts to develop spatial modeling of household water need and water access in Bandung City. Integration of statistics and spatial data expected to water needs model and provide convenience to improve equitable clean water access.
