The Low Down on Compost Toilets

19th November 2019 @ 6:00 pm - 8:00 pm

November 19th is World Toilet Day!

Everybody needs a safe toilet, but billions of people don’t have a one. Without adequate treatment, sewage pollutes waterways and drinking water supplies.

Come learn about different types of toilets- ecological toilets- that turn your poo into compost, don’t need water, and will work even during a disaster. Local experts will present on managing wastewater and biosolids, composting toilets, emergency preparedness, and how composting toilets became legal in Oregon.

There will be a toilet trivia game too, with prizes!

(This is a free event.)

Presentations include

  • Managing the waste of a quarter-million people: regional wastewater treatment and beneficial reuse. Todd Miller and Michelle Miranda from MWMC will present about Eugene/Springfield’s wastewater plan and nutrient recovery biosolid program.
  • Composting toilets: Laura Allen and Tao Orion will present on composting toilets: health and safety, types of toilets, and toilets for disaster preparedness.
  • How composting toilets became legal in Oregon. Composting toilet pioneer Ron Davis will present about the legalities of composting toilets.
