Abstract:
Municipal services account for 4% of the total electricity consumption in India. In wastewater management value chain, 40% - 80% of the operational expenditure is on electricity. Conventionally, energy efficiency studies and interventions focus on electro-mechanical aspects of pumping assets. This research assesses and establishes empirical relationships between urban form parameters like built-up area, pumping station command area, ground coverage, topography etc. with energy consumption at sewage pumping stations in Ahmedabad city. This shall inform city planners in planning energy efficient wastewater systems while preparing spatial plans and simulating energy consumption for new areas based on urban form. Efficient energy consumption would result in cost saving. Research gives indications towards horizontal versus vertical expansion of cities to move towards sustainable development goals like clean water and sanitation, affordable and clean energy and climate action. This would certainly require inputs on other aspects of city planning like land costs, transportation networks.
