Sustainable Initiatives and Practices

  • In partnership with Marin Sanitary Service, the Agency transforms food waste into energy through the Food-2-Energy Progam.
  • Biogas, produced in the digesters during the treatment process, is used to fuel the Agency’s cogeneration system, thus lowering natural gas procurement costs.
  • The Fats, Oils, and Grease (FOG) facility receives FOG from restaurants and markets, which also generates biogas that is used for fuel to power the facility.
  • A portion of the plant’s treated wastewater is reclaimed and used for on-site landscape irrigation, cleaning of tanks and equipment, and chemical transport.
  • Recycled wastewater is sent to Remillard Pond to help maintain a habitat for an endangered species of turtle.
  • Biosolids are beneficially reused as alternate daily cover at the Redwood Landfill, and as land-applied fertilizer for feed crops for livestock.
  • Bicycles and electric carts are used for on-site transportation.
  • Hybrid vehicles are part of CMSA's fleet.
  • Many Agency personnel participate in the Agency's carpool/alternate commute program.


Green Activities


Residents are welcome to come to our office and exchange their mercury-containing thermometer for a new, safe, environmentally-friendly digital thermometer . 


The wastewater agencies of Marin County financially support this program, where residents can responsibly dispose of pharmaceuticals without polluting our waterways.
