Clean water rarely comes cheap in energy terms — pumping, aeration and filtration alone can account for a large share of a municipality's total power bill. As utilities face tighter budgets and stricter emissions targets at the same time, the pressure to treat water without wasting energy has never been higher.

The Training Course in Cutting Energy Costs at Water Treatment Facilities, delivered by the Arab British Fellowship Training Academy, is built around the plant's real energy consumers: pumps, motors, aeration and filtration systems. Participants also examine how energy audits, benchmarking and management systems such as ISO 50001 turn scattered efficiency efforts into a structured, ongoing programme.

The course closes by looking at how renewable sources — solar, wind, hydropower and biogas from the treatment process itself — along with smart grid integration and data analytics, are helping plants generate part of their own power and cut reliance on the grid.

Target Audience

• Water treatment engineers and plant managers responsible for the design, operation and maintenance of treatment systems.
• Energy managers and sustainability officers focused on optimising cost and environmental performance in municipal or industrial settings.
• Consultants and contractors advising on or implementing energy-saving technologies for water treatment plants.
• Policymakers and regulators who set standards for water treatment processes and energy use.

Course Objectives

• Identify the most energy-intensive processes in water treatment, from pumping and aeration to filtration and disinfection.
• Apply energy-efficient technologies such as variable frequency drives, high-efficiency motors and optimised aeration systems.
• Use energy audits and benchmarking tools to evaluate plant performance against industry standards.
• Build and manage an energy management system, including ISO 50001, to sustain efficiency gains over time.
• Assess the feasibility of solar, wind, hydropower and biogas as renewable sources for treatment plants.
• Apply smart grid integration and data analytics to monitor and continuously improve energy performance.
