Sarah Abd El Motaleb

Sarah is a mechanical engineer specializing in district energy systems. Since joining KWL in 2018, she has contributed to all phases of district energy projects—from planning and conceptual design through detailed design, construction, and commissioning support.

Sarah was the project engineer for the piping design and stress analysis modelling for the Bioenergy Research and Demonstration Facility expansion at the University of British Columbia, the False Creek Energy Centre in Vancouver, and the Sapperton district energy system for the City of New Westminster. And she is currently the Engineer of Record for the detailed design, construction, and commissioning support for the Energy Centre at Metro Vancouver’s Waste-to-Energy facility and the Capstan Interim Energy Centre for Corix.

Sarah developed several screening studies to assess low carbon energy technologies/sources for the Southeast False Creek Energy Plant, UBC NDES, Sapperton District Energy System, River District Energy, and Waste-to-Energy for Metro Vancouver. These studies included sewage heat recovery, river water heat recovery, air source heat pumps, waste energy, biomass boilers, and geo-exchange. She also evaluated the greenhouse gas emission and network efficiencies for Canada’s Ottawa-Gatineau district energy system and prepared a study to assess the feasibility of steam-to-hot water conversion for Vancouver General Hospital district energy system.

Sarah is the project engineer for the peer review of building mechanical systems, energy transfer station designs, and construction supports for several new developments for River District Energy, Corix, and Lulu Island Energy Company to ensure the compatibility of connections to the DES.

Sarah is the Stress Analysis Skill Centre Lead at KWL and has developed piping stress analysis models for energy plants and energy transfer stations piping systems using CAESAR II and Start/Prof platforms, which covers the principles and applications for static and dynamic analysis.

In addition to designing models for new buried piping systems, Sarah has also evaluated the impact of vibration caused by construction and excavation on existing water mains, ensuring their structural integrity and reliability.
