sq-engine2Purchased energy (electricity and natural gas) costs are a major expense for the Encina Water Pollution Control Facility (EWPCF). In 2011 EWA developed an Energy and Emissions Strategic Plan, that focuses on increasing the production and use of self-generated energy, with a goal of being energy independent. This plan will be updated in 2018.

Long-Term Goal: Energy Independence

EWA has a long term goal that calls for the facility to work toward independence from purchased energy. While it is not expected that the facility will be able to achieve complete independence, approaching that target is beneficial. The current Energy Strategic Plan includes the following elements to help EWA work towards that goal.

  • Reducing energy consumption
  • Increasing self-generated biogas
  • Increasing self-generated electricity
  • Expanding EWA’s cogeneration facility
  • Reducing air emissions from the cogeneration engines to remove run-time constraints imposed by air permits

As an environmental leader, EWA provides reliable and fiscally responsible wastewater services to the communities we serve while optimizing the use of renewable resources.

Together, we are a model of excellence and innovation.
