Technical factsheet for pumps and motors

The document outlines energy efficiency (EE) strategies for pumps and motors in South African wastewater treatment works, noting that pumping can account for 4% to 30% of a facility's energy use. It categorizes interventions by payback period and energy savings potential, ranging from no-cost operational adjustments to capital-intensive retrofitting. Potential energy savings from these combined interventions can exceed 50%. The factsheet also details various financing options, including municipal budgets, grants, concessional loans, and energy performance contracts, to support the deployment of these technologies.

• Pumping operations in municipal water and wastewater treatment facilities can represent between 4% and 30% of the total energy consumption.
• Energy efficiency interventions for pumps and motors are categorized by their cost and impact; those requiring little or no equipment typically offer savings up to 10% with payback periods under two years, while retrofitting can achieve savings of 10% to 50% for pumps and 10% to 30% for motors with payback periods under three years.
• The combined implementation of various pump and motor energy efficiency interventions has the potential to yield energy savings greater than 50%.
• Financing for energy efficiency projects in municipalities can be sourced through municipal budgets, government or donor grants (such as the Green Fund or MIG), concessional loans from foreign funders (e.g., AFD, DBSA), commercial bank loans, and energy performance contracts via Energy Service Companies (ESCos).
