Water Runs on Power: The Energy Lever Utilities Can’t Ignore

Energy represents one of the largest and most manageable cost centers for water and wastewater utilities—accounting for 10%–40% of operating budgets. Unlike other operational expenditures like labor, utilities can modify the amount of energy used and how much it costs by choosing the right combination of technologies. As electricity demand in the global water sector is projected to reach 4%–8% of total global consumption by 2040, utilities face mounting pressure to reduce costs, manage volatility, and meet carbon reduction targets. In this episode, Bluefield senior analyst Maria Cardenal joins host Reese Tisdale to discuss findings from a new global report on energy optimization across water and wastewater operations. The conversation covers: Where the biggest savings lie: Pump optimization and aeration control represent 70%–80% of total energy consumption, with digital solutions delivering 15%–40% energy savings and payback periods as short as 2–3 months Regional adoption patterns: Why Europe is leading through regulatory mandates like the EU Urban Wastewater Treatment Directive, while North America remains ROI-driven with uneven uptake The technology shift: How utilities are moving from hardware-first approaches to software-led optimization built on AI, digital twins, and advanced analytics Hidden benefits beyond energy bills: Extended asset life, deferred capital expenditures, and reduced maintenance costs that often represent the largest financial returns If you enjoy listening to The Future of Water Podcast, please tell a friend or colleague, and if you haven’t already, please click to follow this podcast wherever you listen.
