The end of the "low-cost energy" era has been written in solid bold font back in 1924 in London’s first energy congress. Thus, though disregarded in Lebanon, power management was a key factor for all energy-wheeled sectors, specifically wastewater treatment facilities, to optimize control strategies and operations. The definition of BM values as a monitoring tool for continuous improvement is the main aim of this paper. Considering energy BM is the most influential tool to optimize WWTPs energetic performance consequently reduce prime & operational costs and GHG emissions; this paper involves many key indicators for future improvement including data collection, data handling and sharing, data validation. WWTPs were benchmarked, incorporating preliminary, secondary (Aerobic Activated sludge), and tertiary treatment processes without sludge treatment. This paper summarizes the results of the first Lebanese WWTPs' energy BM. Data were collected from grouping of 96 WWTPs spread across all Lebanese territories based on: (a) treatment type, (b) designed & implemented size class, (c) weather, and (d) inhabitant population equivalent. The approach to energy BM selected for this study referenced methodology developed and applied for WWTPs worldwide and adopted the stepwise regression as statistical arithmetical method. The results indicated that specific energy demand varies in Lebanon WWTPs between 0.5kWh/m3 and 1.95kWh/m3 according to the most influential KPI's. Aeration consumed the highest energy consumption for all plants. No renewable energy, predominantly co-generation from biogas, or any other alternatives were used except diesel generators as an adjunct for EDL, Official Electrical Network Provider, shortfall. Simulation models are generated for the resulting energy benchmarks.
