Details and speaker profiles: Saving energy in water networks

Join us for a lively discussion in the first of two free webinars exploring the potential for energy recovery in water networks. 

Our first event focuses on the state of the art in water networks and highlights the energy saving potential in such systems. We will also cover the concepts and applications of the latest technology in Pump-as-Turbines (PATs) and briefly present a database tool for selecting PATs.

The session will be led by Dr Kemi Adeyeye (WATEF network, University of Bath):


  • Opportunities for energy recovery with the latest PAT technology (Prof Armando Carravetta, UNINA)
  • Energy recovery potential in on-demand irrigation networks (Miguel Crespo Chacon, Trinity College Dublin)

The sessions will be translated for our international audience.

Opportunities for energy recovery with the latest PAT technology


  • Introduction: water and energy in water networks
  • New strategies for the reduction of the energy use by Ecodesign
  • Pressure reducing strategy by diffuse hydropower generation
  • PAT technology and diffuse hydropower design
  • Conclusions


The reduction of energy use in the industrial sector is one of the major challenges of this century. Water transportation for drinking water supply, irrigation and industry is one of the most energy intensive sectors. The international and European Community are acting to promote the energy efficiency of these systems by forcing different energy reduction strategies. All clear water pumps have been labelled according to new standards and minimum thresholds. Values for energy efficiency are now mandatory, and energy assessments are required for a perfect integration of the pumping systems with the water network. Considering the water-energy nexus, any reduction of water leakage reflects in a reduction of energy use. The pressure reducing strategy is nowadays a consolidated methodology for granting both; an optimal pressure distribution to the end users and the minimum use of natural resources for granting the water supply. The REDAWN project promotes the use of diffuse hydropower generation for recovering energy to be dissipated within the pressure reducing strategy.

The webinar offers an overview of PAT (Pump as Turbine) technology as the best available technology for diffuse hydropower generation in water supply networks. 

Energy recovery potential in on-demand irrigation networks.


  • Introduction: water and energy in irrigation
  • Energy saving measures in on-demand irrigation networks
  • Hydropower energy recovery in on-demand irrigation networks
  • REDAWN irrigation pilot plant
  • Conclusions


Energy consumption has dramatically increased in pressurised irrigation networks compared to traditional channel schemes. Different measures to counteract this effect have been studied during the last years. Cost effective micro hydropower solutions have gained interest due to the existing excess pressure in some locations within pressurised irrigation networks. The Bembezar Margen Derecha irrigation network is analysed under different pressure hypothesis. Pumps-as-Turbines (PATs) for energy recovery will be analysed, assessing their strengths and weaknesses. Insights about PATs design in irrigation will be presented, as well as the REDAWN real pilot plant and its benefits achieved during two years operation. 

There will be a live Q&A after the presentations with all of the speakers.
