Initiative for a water utility energy efficiency programme in Lesotho

To develop a national initiative for the reduction of energy consumption in water utilities in close cooperation with the Water and Sewerage Authority (WASA) of Lesotho.

Main activity and output: 
  • Analyse the barriers for improving energy efficiency in water treatment plants and reducing water consumption at end user level
  • Develop and implement a tailored energy efficiency management plan to generate energy savings in WASA facilities
  • Design a water efficiency awareness raising campaign for end users
  • Assist WASA in the implementation of initial demonstration projects
  • Design measurement and verification protocols for water and energy savings generated by these pilot projects
  • Scale up the project through energy performance contracting, developing a tender for ESCOs to encourage further investment, introducing the use of third party financing and if applicable, carbon finance
  • Organise a workshop to share best practices with Government and other public facilities in the country
Expected impact: 
  • A reduction of energy consumption at approximately 10 WASA water treatment plants through the initial implementation of the energy efficiency master plan and demonstration projects
  • Public awareness leading to a nation-wide reduction in end-user water wastage, thus reducing water treatment plant energy consumption
  • Reduction of carbon emissions
  • Reduction of the high maintenance costs of inefficient equipment and plants
  • Increased water availability for end users
  • Scale-up of similar approaches by other public organisations in Lesotho and other countries in the region
