Heat island effect has been a significant factor contributing local climate change at the city level. As a necessary infrastructure in urban system, Wastewater Treatment Plants (WWTPs) have been recognized as a contributor to global climate change due to its greenhouse gas emissions and huge energy and resource consumption. But their impacts on local climate change have been hardly studied. Landsat TM/ETM+ images, infrared remote sensing imagery, were used to study heat island effect of nine WWTPs in Harbin by retrieving surface temperature during 2000-2013. Results showed that heat island intensity of nine WWTPs increase by 53% during the time. Principle Factor Analysis and multiple linear regressions showed that heat island intensity of WWTPs are positively correlated with treatment volumes, urban surface temperature and negatively correlated with discharge standards, construction condition and treatment process.
