39The environmental impacts resulting from sewer networks are best analysed from a life-cycle 40 perspective to integrate the energy requirements of the entire lifetime in the infrastructure 41 design. The energy requirements for pumping wastewater depend on the configuration of the 42 city (e.g., climate, population, length of the sewer, topography, etc.). This study analyses and 43 models the effect of such site-specific features on energy consumption and related effects in a 44
