A composting toilet (M54W Trailhead) will be installed on the campus of Lewis & Clark College in Portland, OR. Composting toilet systems generally provide a lower cost, lower impact option for restroom locations lacking existing access to utilities or in areas where improving access would be prohibitively expensive. Composting toilets provide significant environmental benefits when compared to conventional flush systems. In Portland, this system has the added benefit of reducing impacts on an already taxed sanitary and storm system, reducing its contribution to combined sewer overflows to the Willamette River.
