Composting Toilets

All standard (flushing) toilets at the Harris Center have been replaced with composting toilets — waterless, odorless systems that utilize aerobic bacteria to transform human waste into a rich, well-stabilized mulch. These systems require no water for flushing, thereby conserving both water and electricity.
