So Mary, I see your post inquiring about Clivus Multrum is seven-years old. I'm just wondering what you finally did? We installed a Clivus when we built our year-round home on Key Largo in 1992/1993. No regrets. Though the local permitting system was unfamiliar with waterless composting toilets, and did not make it easy for us, it was allowed. Yet, no effort was made to learn from our experience so they would be more prepared next time. Jim Duquesnel (park_bio@yahoo.com)
