Greeley and Hansen, A TYLin Company, is collaborating with the Carmel Area Wastewater District to relocate the wastewater treatment to address climate change.

The Carmel Area Wastewater District is preparing a long-term wastewater treatment and coastal hazards planning roadmap, which includes alternatives analysis of relocating the wastewater treatment plant to address expected seas level rise for the next 40 years. The goal of this project is to develop plant relocation concepts for the wastewater treatment plant in response to climate change and resulting sea level rise.  

The existing Carmel Area Wastewater District (CAWD) Wastewater Treatment Plant (WWTP) is a 3.0 million gallons per day (MGD) average annual permitted discharge flow facility that uses activated sludge for secondary treatment. The concepts developed for the new Carmel Area Wastewater District plant will be a Water Resource Recovery Facility (WRRF), and will take into consideration available treatment technologies and incorporating resource recovery to further serve the local community.  


Project Highlights: 

  • New water resource recovery facility, pumping station and equalization basin 
  • Address sea level rise expected to threaten the site of the existing plant 
  • Incorporation of water reclamation technology to mitigate higher frequency and duration of local drought conditions
