Water and/or Wastewater Treatment Plants are equipped with aeration and digester blowers, raw sewage pumps, UV systems, pumps, motors and other equipment often operating non-stop throughout the year. This equipment is energy dependent and requires a steady supply. The energy demand that this equipment creates can provide an opportunity for new energy conservation measures.
This presentation aims to share OCWA’s experience with energy savings programs focused on the Water and Wastewater sector. Energy efficiency in water and wastewater facilities can be categorized into three types; capital upgrades (equipment and facility), operational changes and behavioral changes. The presentation provides information and results from projects in each category before and after the energy efficiency projects were implemented. It also provides some key metrics and highlights the lessons learnt.
