The effect of climate change is primarily manifested through water: melting glacier, raising sea-level, increasing frequency and intensity of droughts and floods, etc. The increasingly unpredictable water availability and contaminated water resources further exacerbate water scarcity around the world. In addition to affecting water supply, the changes in temperature and rainfall are also expected to impact water demand.
In this research seminar, we discuss the relationship between weather and residential water demand in Singapore. Using monthly water consumption data for all households from 2011 to 2020 and the hourly water consumption data for households with AMR, we evaluate both short-term and long-term relations between temperature, rainfall, extreme weather events and residential water use. We also aim at disentangling the effect of weather and other demand management initiatives on consumption behavior.
